Autofill Canister Missing Liner?

[cookie.monster]

Hi All,

Since swapping my pool to salt a system I've been noticing I seem to need to add more salt person than I would expect which led me down the road of leak investigation. I went out to adjust the autofill valve for a lower water level today (this is why the float is below water level in the pictures) and now I'm starting to suspect this could be from the autofill canister. The canister is concrete and it doesn't have any liner on the inside and I can see where the concrete appears wet above the water level due to the concrete absorbing the water.

Is this a normal situation for an autofill? If not, any recommendations on how to proceed?

Thanks!

Welcome to TFP.

Looks like that builder installed the budget autofill and cut corners not buying a canister.

I think you will have a problem installing a liner in there.

I would waterproof the hole with a waterproof membrane like Basecrete...

Thanks, the other thing to note is the equalizer line does has a 3/4 female thread in the cement basin. Is there any smaller type of canister I could install instead?

I don't know. You are going to need to search around and see if you can find a canister that will fit the hole.

I seem to need to add more salt

In Phoenix, you should never have to add salt, unless you drain water from the pool and add fresh. Salt is added via fill water, acid, etc. Your salinity should rise over time, not fall.

I'm also on a sand filter and with regular backwashing expect to lose a bit but not to the extent that I'm needing to replace each year.
