HOW TO Clean A Durastill Water Distiller in 3 Easy Steps

how to clean a durastill water distiller

 

EASYCLEAN Step #1: Clean the distiller boiling chamber

EASYCLEAN Step #2: Clean the water storage tank

EASYCLEAN Step #3: Replace the filters

Note: You will find everything that we use in this video and guide in our Ultimate Durastill Cleaning & Maintenance Package. 

CAUTION: Before you service or clean your water distiller system ALWAYS UNPLUG your distiller from the electrical outlet as a safety precaution and make sure your distiller is COOLED DOWN and not hot. Never open the lid to the distiller while it is operating. Hot steam may cause severe burns.

Before you clean your distiller make sure you drain your water storage tank so that it is empty. Now you are ready to get started!

Step #1: Clean The Distiller Boiling Chamber

  1. Remove the boiling chamber lid and keep it off the entire time while you are cleaning the boiling chamber. You don't want any citric acid or any other vapors to go down the condenser coil during boiling chamber cleaning because it will stick to the condenser coil and change the taste and quality of the distilled water.
  2. Drain your boiling chamber using the side drain faucet. Look inside the boiling chamber and remove any large pieces or chunks of scale. Now you can drain out some of the smaller particles. Sometimes there is so much filth and buildup in the boiling chamber that the side drain will clog or plug up when you try to drain it. Usually the filth, scale, and deposits in my distiller boiling chamber looks actually kind of like white sand (that is the best way I can describe it, but the most common colors are white, brown, and black depending on your water source). Your goal here is to just remove any large chunks and drain out what you can. If it starts to drain and then gets plugged up, don't worry. Just get out what you can and then don't forget to close the side drain. 
  3. Fill up the boiling chamber so it is ¼ inch above the water fill line. This is easy to see because there is usually a mineral or scale line that goes around the boiling chamber. It kind of looks like a soap scum line in a bathtub or a mineral deposit line around a sink. We want the Durastill Still Clean to clean off this scale and buildup, that is why we want to fill it above this water line level. Basically the Still Clean will clean everything below the water level. Make sure you don't fill up the boiling chamber completely because you don't want the filthy water and still clean to go into the condenser coil tube at the top of the boiling chamber.  I like to use a pitcher of tap water and manually fill up the boiling chamber until I get the water line 1/4 inch above the fill line. 
  4. Add ¼ cup of Durastill Still Clean to the boiling chamber. Durastill Still Clean is made especially for cleaning Durastill Water Distillers! Still Clean has one simple ingredient: citric acid (found in lemons, limes and other citrus fruit).  This food grade citric acid distiller cleaner is used to clean inside the stainless steel boiling chamber and all of the components therein (heating element, float, etc.). Still Clean is the safest, fastest, easiest and most effective cleaner for Durastill Water Distillers! It does an excellent job of dissolving minerals, water scale and other boiling chamber water distiller residue.
  5. Plug in the Distiller and bring the water to a boil to "activate" the Still Clean. I timed my distiller and it took about 30 minutes to bring the water to a boil (it takes longer than normal to boil because the lid is off). Let the water boil for twenty minutes. And then, TURN OFF the distiller by unplugging it. We just want to heat the water up to help "activate" the Still Clean and improve the descaling and cleaning process.
  6. Let the still clean sit in the boiling chamber for 8 hours. Don’t forget to leave the LID OFF this entire time you are cleaning the boiling chamber of your distiller, even while the distiller is sitting and cooling down. After being turned off and sitting for 8 hours, your distiller will be nice and cool for you to work on it. I like to clean the boiling chamber in the evening and then just let it sit over night to maximize the cleaning power of the Still Clean. That way the Still Clean will keep cleaning and descaling for the next 8 hours overnight. Then I finish cleaning the boiling chamber the next morning.
  7. Drain the scale, residue, debris, and dirty water from the boiling chamber out of the side drain.  Now you will see the scale and buildup that was on the walls of the boiling chamber in the water (some of it floats on top of the water and some of it sinks to the bottom of the boiling chamber). Depending on the chemicals in your water this may look different in your distiller, but mine is brown or white colored and has a fine "sand-like texture". Next, open the side drain faucet of the boiling chamber and let it drain out. If the boiling chamber has not been cleaned in a long time or if you just have a lot of scale, buildup, and junk in your distiller, you may find that the drain gets clogged. If that is the case, then just take a spoon and scoop out the junk through the lid hole on top of the distiller.  Be careful with the spoon so you don't bend or damage the float, float rod or heating element.  Just be patient and take your time. I like to softly wipe down and scrub the side walls of the boiling chamber with a sponge. NOTE: If the boiling chamber is not as clean as you want it, then repeat the above cleaning process (REPEAT STEPS 3-7). For this distiller I am going to clean it again with Vinegar to show you how Ultimate TIP: As a good rule of thumb, if the scale on the heating element and boiling chamber walls are still the thickness of a credit card then clean it again! 
  8. After it's clean, fill-up the boiling chamber and flush it out.  Close the side drain faucet and fill up the boiling chamber with water again (slightly above the fill line).  Then open the drain valve and drain all the water out to flush out and empty the boiling chamber (I usually fill it up and drain it twice, just to make sure everything is flushed out).  
  9. Fill up boiling chamber and add 1 teaspoon of Durastill Still SWEET.  You MUST fill up the boiling chamber with water so you can steam-clean the water storage tank in STEP #2 below.  I just manually fill it with a water pitcher and add one teaspoon of Still SWEET. Why add Still SWEET? Adding one teaspoon of Still Sweet is optional (but highly recommended). Still SWEET keeps the minerals and scale soft and "putty-like" and prevents it from sticking to the heating element and boiling chamber. Still Sweet is basically a food grade water softener made of salts. Still SWEET will make it easier to clean and drain your boiling chamber the next time you clean it. Don't worry it DOES NOT distill across and it stays in the boiling chamber. You always want Still Sweet in your boiling chamber.  Ultimate TIP: Still SWEET is one of the secrets to extend the life of your Durastill Distiller up to 30 years!
  10. Tighten down the distiller lid to seal the boiling chamber. Congratulations! You just cleaned your boiling chamber! Now it's time to clean your tank. What if you have a manual water distiller and you don't have a stainless steel tank? Then you can skip Step #2 and go directly to Step #3.

Step #2: Clean the water storage tank

We are actually going to “steam clean” or “autoclave” the stainless steel water storage tank to clean and sterilize the tank at the same time.
  1. Remove the Durastill Post Filter and the line. You will need to loosen the C-clamp and remove the tube from the bottom of the condenser coil (this is where the water comes out of the bottom of your distiller). TIP: you will be connecting the steamer tube into the same hole that the post filter connects to on the tank. WARNING: You never run steam through your post carbon filter because that will ruin the filter, only run steam through the steamer tube!
  2. Connect the “steamer tube”. There are two types of steamer tubes depending on the size of your storage tank: Short and Long. Connect the "short steamer tube" directly from the end of the condenser coil to the tank (if you have the 4 or 10 gallon tank). Connect the "long steamer tube" directly from the end of the condenser coil to the tank (if you have the 25 gallon tank). You just attach the vinyl tube to the metal steamer tube, since the opening is at the front of the tank. Make sure you have a good enough seal to prevent steam from escaping.
  3. Plug in the water distiller system. You will hear the fan turn on and that is an easy way to tell if the distiller is on.
  4. TURN OFF the fan switch. Why turn the fan off? When the fan is on, it cools down the steam into water. When the fan switch is OFF the steam does not cool down. The hot steam goes directly into the water storage tank through the steamer tube and steam cleans or autoclaves the tank. This will sterilize your stainless steel Durastill Water Storage Tank. TIP: It will take about 20 minutes before the water will start boiling and build up enough pressure to force steam into the water storage tank.
  5. Steam Clean the tank for 20 minutes to Sterilize. After the water is boiling start your timer.  How do you know if the water has started to boil? You can hear it boil in the boiling chamber. You see steam coming out of the VOC vent on the top of the distiller and if you have the long steamer tube you'll see steam coming down it. WARNING: the stainless steel water storage tank will become very hot during this sterilization process. Do not touch the tank or you could get burned!
  6. After 20 minutes UNPLUG the distiller to turn everything OFF. Let the whole system cool completely before you continue (that includes the water distiller head and the storage tank). I would recommend you wait at least 2 hours. Congratulations you just cleaned your stainless steel water distiller storage tank! You're almost done.

Step #3: Replace The Filters

Some of you may have a manual fill Durastill Water Distiller (30H) or you may have an automatic water distiller system in “manual mode”. Either way if your water line is NOT hooked up through your pre-filter to your distiller then you have no pre-filter to replace, so you can skip that step. You just need to replace your Post-Filter.

For everyone else, our last step is to replace the Durastill Pre-Filter and the Durastill Post-Filter. 

  1. If you're changing the Pre-Filter, TURN OFF your water line from your pressurized source of water. You will have a water mess if you don't. (Skip this step if you have no Pre-Filter)
  2. Unscrew the Durastill Pre-Filter and replace it, then reconnect the "in-line" filter(Skip this step if you have no Pre-Filter) 
  3. Disconnect the Steamer Tube. To remove the short steamer tube, pull down to disconnect it from the condenser coil and then cock it off to the right or left and pull it up and out of the 4 or 10 gallon water storage tank. To remove the long steamer tube unscrew the c-clamp from the cooling coil and then pull the metal tip out of the 25 gallon tank.  
  4. Unscrew the Durastill Post-Filter and replace it, then reconnect the new post filter and line to the water storage tank. You can re-use the 90 degree elbows that screw into the post filter for many years, so don't lose them. Then screw in the 90 degree elbows into the new Durastill Post filter. There is one for each end of the filter. Connect the flexible tube to the condenser coil. Tighten the C-clamp and make sure you get a good seal. Then put the smooth 90 degree elbow into your water tank hole.
  5. TURN ON your Water Supply. If you turned off your water supply to replace your filters, Don't forget to turn it back on so that water will flow to your boiling chamber.
  6. TURN ON the fan switch. With the fan switch turned ON you will be making distilled water again because the fan will cool the steam back into water.
  7. PLUG IN your distiller and let it distill at least 1 gallon of water (this should take 2-3 hours depending on your distiller model).
  8. Then drain the water storage tank and discard this first gallon of water.

Congratulations You have just learned how to clean the inside of your Durastill Water Distiller!

How do you extend the life of your Durastill Water Distiller up to 30 years?

Here are the Ultimate Cleaning & Maintenance Guide TIPS to extend the life of your Durastill Water System up to 30 years:

You must keep your distiller clean to maximize the life of your water distiller.

  • You should drain your boiling chamber and then add Durastill Still Sweet to your boiling chamber at least once every month. Even better... the Durastill Engineers recommend draining your boiling chamber once per week and then add Still Sweet! Ideally you would drain it once per week, but I would rather have you drain once a month than not drain it at all. Draining your boiling chamber will keep your boiling chamber very clean and running optimally.  Don't forget to immediately fill up the boiling chamber. 
  • You should clean your water distiller system and replace your filters every 6 months (12 months maximum).
  • You should inspect and clean the condenser coil  and fan every 6 months. But you will first need to remove the front panel of your water distiller. It's easy, you just unscrew a few screws and then slide the panel off. Now you have access to clean the coil and the fan.
  • To clean the condenser coil you can either vacuum up any dirt, dust, and debris, or you can use an air compressor and just blow it off to clean in between the coil fins. When the condenser coil is clean it cools the steam into water most efficiently. 
  • To clean the fan (blades and motor), vacuum the fan blades and then wipe them off with a vinegar dampened sponge. You don't want to get the sponge dripping wet because you don't want any liquid going into the fan motor. Next vacuum out the motor coils to get any dust, dirt or debris off.
  • You should inspect the boiling chamber lid and opening every 6 months.  If it is dirty and you see scale buildup then clean it with white distilled vinegar. Scrub off any dirt or scale around the opening of the boiling chamber. Then clean the boiling chamber lid and cross bar. If the scale won't come off, you can soak the lid in white vinegar for about 20 minutes or use a more aggressive cleaner like lime-a-way to dissolve minerals and scale.
  • You should replace the "Float Gasket Set" and "Heating Element Seal Kit". These rubber gaskets wear out over time and should be replaced about every 5 years.
  • Good ventilation will ensure the most efficient operation.
  • For best performance, we suggest a room temperature between 40 degrees and 85 degrees Fahrenheit (4.4-29.4 Celsius).

How To Clean Water Distiller: Frequently Asked Cleaning & Maintenance Questions

Why do I need to drain my boiling chamber (AKA evaporator tank)?

During the distillation process, raw source water enters the boiling chamber. The water is boiled and turned to steam which will become the distilled water. Impurities, chemicals, dissolved minerals, and dead bacteria are left behind in the boiling water. Over time the concentration of these impurities will build up and cause foaming. If the foaming is severe enough, it will rise and spill into your distilled water reducing its quality. Draining the boiling chamber minimizes foaming and maintains the best purity of your distilled water.

How often should I drain the boiling chamber (aka evaporator tank)?

David the Durastill Engineer said, "Starting out, you should drain your evaporator tank once a week for average usage and water conditions.  If your distiller is running all day or if you have a high amount of impurities in your water or you have other special needs you should drain it more often if not daily."

The Durastill owner's manual actually recommends draining your boiling chamber after every 20 gallons of water you distill. To maximize the life of your distiller we recommend you drain the boiling chamber once a week.  But for most people it might not be practical to drain the boiling chamber every week, so we recommend you drain it at least once a month.

How often to clean water distiller?

We recommend you clean your Durastill Water Distiller every 6 months. It's a good idea to take the lid off the boiling chamber and inspect the boiling chamber once a month. You may notice a build up of scale and deposit forming on the walls and heating element. These deposits are the impurities the distiller has removed from your drinking water. If they are allowed to build up, the efficiency of the heating element is reduced and the corrosion resistance of the stainless steel is diminished. Ultimate TIP: A good rule of thumb is when the scale is about the thickness of a credit card it is time to clean your distiller! 

Why should I use Still SWEET?

Durastill Still SWEET is made especially for Durastill Water Distillers! Still Sweet makes flushing or draining your boiling chamber easier because the mineral deposits and scale remains soft (kind of like putty instead of like sand). The tagline is "Keeps Minerals In Solution to Minimize Scaling."  It prevents minerals and scale from becoming hard like a rock and sticking to the inside of the boiling chamber including the walls, heating element, float and other components. This is NOT A CLEANER. Still Sweet is basically a food grade water softener made of salts that stays in your boiling chamber while it operates.

Still SWEET is made with two simple ingredients (these are 2 types of salts): Sodium Hexametaphosphate, Sodium Tripolyphosphate.  It does NOT distill across with the water. The Still Sweet remains in the boiling chamber until it is drained out (hopefully every month when you drain it). Don't forget to add a new scoop of Still SWEET to the first new batch of water added after you drain the boiling chamber. This product makes draining your boiling chamber easy and extends the life of your distiller!  For optimal performance we recommend using factory supplied Still SWEET for Durastill Water Distillers.

How to clean stainless steel water distiller?

A Durastill Water Distiller is a stainless steel water distiller made in the USA of 316 surgical grade stainless steel.  To clean stainless steel water distiller inside: use Durastill Still Clean. To clean stainless steel water distiller outside: use white distilled vinegar. 

Do you recommend cleaning water distiller with vinegar?

Instead of using Durastill Still Clean you can use Distilled White Vinegar to clean the inside of your boiling chamber.  Costco or Walmart have great deals on white distilled vinegar.  I have cleaned my distiller with both white distilled vinegar and Still Clean, but Still Clean works much better at dissolving and descaling the minerals and build-up. Vinegar does a great job of shining and polishing the inside of the boiling chamber. The Vinegar will really stink up the room or area where the distiller is getting cleaning. As the Vinegar boils and releases fuses it creates a really strong vinegar smell the entire time you are boiling it and letting it cool down. In the how to clean video it make the whole garage smell like vinegar and we had to open the garage door to air it out. Now I prefer to use Still Clean, but vinegar is an option if you want. In the how to video I cleaned the boiling chamber the first time with Still Clean and the second time with Vinegar.

How do you clean the outside of your Durastill Stainless Steel Water Distiller?

I highly recommend using white distilled vinegar to clean the outside of your distiller and water storage tank. It does a great job! If you need something stronger to remove really stubborn scale or buildup you can use a more aggressive cleaner such as: Lime-A-Way or a Stainless Steel Cleaner (watch the video for more information and to see the results).

What is included in the Ultimate Cleaning & Maintenance Package?

-1 pound bottle of Still Clean to clean your boiling chamber (this should last about 3-5 years depending on how dirty your source water is)
