Inline Water Purification System for Water Heater

Hey guys,

I use a tankless water heater for my honeypots, I want to install an inline water purifier to help prevent scaling issues. Something that could easily hook up to PEX lines. Would anyone have any suggestions?

Thank you,

The aqua-pure in-line descalant filters have worked for me before. I have not, however, ever used them on a tankless water heater system. Only on tanked systems and for aquaponics activities.

Here is an example.

You can also get similar filters that fit just about any configuration where you could put in a water filter cartridge. The ones that look a bit like this:

Where the first is like sediment, then carbon, then the last one you put in a softener/descalant/whatever the fuck else you want. They work with the PEX you are mentioning as well.

Good luck and let us know what you decide to use!

Thank you for that! I’m gonna hit up 3M, had no idea they make these.

I would just use RO or preferably distilled water instead of an entire filtration system just for honey pots. Just start with clean water the filters are unnecessary restrictions and will be more hassle in the long run

Keep in mind to ensure the filtration setup you use inline can handle the heat from the water over time and not burst seals or ruin membrane and or media from the filtration cartridges or columns. Get in depth with this and even think about the compounds present or the make up of your water after filtration. Not all water is filtered the same for the exact same uses. RO/DI water that is heated can be more corrosive to metals. Food for thought.

I always put the filters on the supply side when I do this. So the water is treated going into the heater, not coming out.

I have never used these for recirculating systems, although I did just learn there are people that are using RO and filtration for runoff and what not - which seems insane while simultaneously making me feel like I was so out of touch with the green movement! And I try to be as sustainable as possible - as it has multiple benefits beyond being good for the planet.

Most grows should be treating their runoff. I know the facility I worked at and built quite a bit for ended up doing water treatment for the 40k gallows of just waste water from their RO system & runoff to go back into the local supply and ducts. Given they pull from well water and treat it for thousands of ppms worth of impurities just to be able to use it for watering etc. they now have multiple buildings with 30-50k+ gal of mixing tanks in each setup. The amount of water they filter through and treat is crazy. Trying to be as green as possible for it all is the even bigger feat. The best thing I seen that they did while my father in law was working there still was a misting aromatic diffuser for the aromas from the grow using the waste water that was treated.
