I have 150 gallons of fresh water tanked. I have a Clearsource Premier RV Water Filter System and a HQUA-OWS-12T Ultraviolet Water Purifier Sterilizer Filter for my skoolie. Should I install them before water enters my holding tank or after the tank, before the pump?
 
Having seen the inside of some tanks, over time, I'd filter after the tank. But, ideally, you'd have some kind of basic sediment filter on the tank fill to minimize the junk that enters the tank.
 
I would run the filter before the tank and the sterilizer after the pump on the kitchen/sink lines, and I wouldn't worry about the shower lines or anything else.

But I also wouldn't be running a sterilizer on my water unless I was an AIDS patient or was otherwise immunocompromised because I had an organ transplant.
 
I have a sediment filter just before the pump, and my water filter is only on a single faucet in the kitchen sink (for drinking water, cooking etc.).

The rest of my faucets and shower etc are not purified.

That's what I did too and it's working well so far. My filter leaks sometimes, so I have it mounted in a shallow plywood box lined with shower pan liner material. I intend to put one of those leak detector alarms in the box, but haven't gotten around to it yet.

Just an aside...if you mount a micro switch above the bottom of your leak area, use the normally closed contacts and rest the actuation arm on an aspirin it makes a very reliable and inexpensive water leak detector. :smile:

Clever!

This idea led me down a brief internet search rabbit hole. An even cheaper version I saw was a DIY "switch" made by gripping the aspirin in a clothes pin between two wires. Along with the 12v air horn I have in the garage, I could have a working water detector tonight!

That's pretty clever, crude but effective :wink1:
 
filters work better after a pump.

the suction or head of most pumps would barely pull water through a coffee filter. im surprised you folks are saying you have good results like that.

there is no chance a little rv demand pump is going to pull water through multiple cartridges of your clearwater premier rv water filter. that thing will have to go after your pump.

most would have a prepump screen to catch bugs before they get in the pump, and then a cartidge filter after to clean the water. you'll want a big pump for multiple cartridges. try and find paper cartridges for it or pull one if your pump loses to much pressure with it.

You could install a sediment filter on the inlet to your water tank to keep junk from getting into the tank. Then the pump with suction screen followed by the cartridge filter then the UV sterilizer.

I would treat the water with chlorine when you fill the tank to keep things from growing in it provided that the cartridge filters remove chlorine.
