This is at about 4 years old. I think it has lightened up a bunch. But maybe that's from running the chlorine levels a little higher than I should have. Not sure.

Here are my full tests from today. Still trying to understand if chemistry caused my problem. I will update again when I pull the manifold.

That’s what I don’t get. My ph tends to run high from the spa waterfall and the swg. Every time I test it’s solid purple and then 1 acid demand drop gets it to 7.4 color so I add 4 -6 cups of acid. Usually about once a week for a 20k gallon pool. I am really struggling to understand the issue.

Thanks for the quick responses. This will be my protect over the next week. Then to decide if I should open up my rusty manifold or just leave it. I found a local heater that someone is selling and I may just swap my unit. I also have to check my TA a few times. I am wondering if running...

I have a pre 2/2021 master temp so no heater bypass on heater circuit board. I want to connect an auto heater bypass to my IntelliCenter. Does anyone have instructions for how to do that. I have the plumbing diagram so that part is a known. I am looking for the actual port to use on the...

Just the metal in the filter. Not really bad but shows rust. I have to pop off the manifold at some point. Probably will install an auto bypass since my intellicenter should handle it.

I wonder if adding stabilizer to the skimmer did this. I don’t use a skimmer sock and thought it was ok since it gets to filter first. This was usually once a season in the spring to get cya up. But maybe that caused an issue. I am beyond sad that this happened this quick as I thought I...

What type of chemical problems can cause it? My ph never gets really low. It may get a little high in the middle of winter but using the LSI calculations seem to suggest when water is cold that doesn't matter as much. I have been maintaining the pool and use all the tfp testing kits and try...

Do you have the specs on the bolts? Thanks for all your help!

I didn't see any water coming out of the bottom hole. I tried one further up (that still could be turned) and didn't see water there either. I was running in pool mode which is a slower RPM (2200) vs spa mode. Maybe my spa mode is turned up too high? I did have it set near max (3100) trying...

I took one of the bolts out and no water came out. Pump was off. Should that be done under pressure?

Any risk to waiting for it to fail by leaking without the bolts removed? Or should I be proactive in fixing it? I would still like to understand what is happening that caused it. I try to keep ph in check it always goes to 8 and then I dose with acid to about 7.4. My chlorine levels have...

If water comes out does that mean the exchanger has failed?

There isn’t a check valve between ic40 and the heater. Could that be an issue? It really looks like corrosion from chlorine to me. But I don’t know how it could be outside the manifold. The bolts are toast. I am going to have to drill them out likely. So not trying to remove unless I...

I think they just put a label up there. The real back wash line is on the bottom of the slide.

How long does that normally take? A few years ago in the Texas freeze my heater was accidentally on for a few days. I was debugging a HLS error and saw my bolts are all rusted on the manifold. Trying to figure out what happened.

It’s only 4 years old.

What causes this kinda corrosion on these outside bolts of Pentair heater manifold case?

If the board is upgraded can the new board be hooked up to intellicenter via the rs485 connections?

What did you end up doing? I know it’s an old thread but in a similar position with my pool. Hard to find people that have the prosoco OH100 consolidator. Will keep looking. Have some stain proof 40sk that I am going to try after the consolidator or maybe just by itself. Have used...

Here are some pics from over 2 years later... any recommendations for what I should replace these rock with? I am thinking about some rock look porcelain tiles but I am sure that might be a challenge. I have no idea if this is from the salt levels, just plain erosion or just really bad...

How long have you had the cleaner? What did you have before? I have a Pentair racer now and thinking of going the Polaris route... either the p280 which seems to be recommended a bunch. But these seem like they would do a great job.
