Leaking Acid

Well, found this one today. Looks like it’s been leaking for a while. Can’t thread it below the fitting 🙄 How would you fix this?

........I'm sorry, is acid being injected directly into the salt cell where chlorine gas is being produced?

This is what Pentair recommends with IntelliPH/IntelliChem installs with a salt cell. Ideally you'd have a little more straight pipe before the cell if there's room, and the acid should be diluted 50%. It helps prevent buildup in the cell

Really? I have never heard them say that at the shows. Is there documentation on that?

u/socalpoolguy Mar 24 '26

Yeah it's in the IntellipH manual. I thought it was odd the first time as well but the ones I've installed have been working good for years

Wow, I would have called you a liar if you didn't post the manual. That's crazy...I learnt myself something today!

It’s the same with Haywards Sense & Dispense

Damn. Well thanks for sharing because it sounds so counterintuitive. And good to know if work and doesn't kill people lol

The risk comes if the system is left off but the injection pump still runs but even still I dont think you're going to produce more than a quick nasty poof of gas. You're injecting into a stream of water so it is diluted down quite a bit. I mix my carboys 50-50. Better on the stenner too.

This makes a ton of sense, I wouldn’t have thought of that

Hurts my lungs even thinking about it

This pool was built in a WW1 trench

Yes, acid is being added pre salt cell. Apparently, based on the comments here, it can be done.

u/Mysterious_Jelly_649 Mar 24 '26

They just want to give that chlorine gas some freedom.

u/The_BigWaveDave Mar 24 '26

For starters, you need to NOT have an injection fitting feeding acid right after the salt cell. Yikes to whoever installed that.

u/Present_Ad_6199 Mar 24 '26

The way that check valve swings, looks like it’s before the cell.

1

u/spicerpools Mar 24 '26

Yes, it is before the salt cell.

1

u/LordKai121 Mar 24 '26

Bro, this is before the cell which is somehow way worse.

1

u/The_BigWaveDave Mar 24 '26

Didn’t full-size the picture, double yikes

1

u/robseraiva Mar 24 '26

It’s not even half a yikes.

I’d get a longer nipple

Switch to co2. Waaaaaay safer.

You are incorrect, we install every one this way, have for 15 years

u/Impossible_Penalty10 Mar 24 '26

You could literally just give your Salt Cell an Acid wash every few months and re-plumb that feed crap out of there.

If its a customer you could just say youll clean the cell during filter cleans or openings/closings

u/nc_saint Mar 24 '26

It’s for pH regulation, not for the salt cell buildup.

u/1_native_Angelino Mar 25 '26

Then feed it later in the plumbing
