Reverse Osmosis for Pool

Some folks use a RV water softener for their pool fill water.

^^^^This.

I have not seen a thread on RO in Nevada...maybe @mknauss knows. In Rancho Cucamonga, @Rancho Cost-a-Lotta says ~$600 is a good price (20K gallon pool).

Do you have a whole house softener? I also live in Vegas, and I am having mine connected to the pool auto fill this week

I've been contemplating something like this as well. We have very hard water in my area and am considering adding a softener dedicated to my pool in the pump room. In my case, the pump room is detached from the house so trenching & running a pipe from the residential softener would cost more than just adding a second softener for the pool.

I had an interesting thought this morning when thinking about this topic. Why drain the pool at all? Why not recirculate the existing pool water through a dedicated softener? Tap off the recirculation plumbing circuit after the filter and send some of the return water through the softener and back to the pool. Run that until the water in the pool reaches the desired CH levels, after that just run your auto fill water through the softener. In our area, we have pretty significant water use restrictions so this seems like a good idea and could save thousands of gallons of water as well as $$. I may change my mind as I think about it longer but for now the only thing I can see that might need a solution is the pressure of the circulation circuit vs. normal residential water supply pressure and if it will be high enough to operate a softener. If it's not in the acceptable range for a softener, a booster pump or regulator may be needed.

And that's why I'm just simple dirt engineer and not a chemical engineer. Thank you for pointing that out. I'll just set up a softener for the makeup water.

If you are on top of recharging your softener (to avoid calcium actually making it to the pool through autofill) you should in theory, never have to drain and refill again or it would climb so slowly than a partial drain and refill should do it.

I’m in Vegas as well and had the reverse osmosis process done on our pool last year…

The prices may have changed, but the quote I received was for pools 5k-18k gallons, $600…for pools 18k-30k, $650.

I used City Wide Pool Service.

It was a very simple process, but a trailer will need to be parked outside your house for 12-24 hours and a generator will be running that whole time. You may want to inform your neighbors!

Considering our location in the desert and our water consumption awareness, I feel the RO process is the more responsible choice as opposed to draining and refilling.

Good luck!

I understand that, but there’s still less waste being generated from the localized RO process as opposed to running it through the wider drain system.

To me, it’s the more responsible option.
