Impeller and motor seem ok. Motor seems to turn fine.

I also noticed leaking from the top of the filter. The o-ring at the base of the multiport valve is visibly cracked. Do I need to take the MPV apart and check any other parts before I order replacements, or just order the o-ring? Will I need to re-pipe to remove and re-attach the MPV, or is...

I was finally able to get outside to take apart the pump. Here are some pictures. The blue liquid seal was probably applied over the gasket when the previous owner switched out the motor in 2020. Does this automatically mean I need to replace the seal plate also? Other than that (and for...

Stickers are numbered 1-4 from front to back. Sticker 1 is dated 2012 when pool was built, sticker 2 has a 2020 date, sticker 3 has a 2021 date. When we bought the place the previous owner provided receipts for replacing a Jandy Check Valve that failed due to a freeze and a pentair replacement...

Hi Jim, Thank you for your continued help. I was able to try the slow stream of water test today and none of the water was being sucked into the pump. I will keep looking for leaks in daylight hours. The one major difference I have noticed is when the pump is on there is air flowing out of...

Another test you can do is run a slow stream of water over the wet end of the pump when it is trying to prime. It is makes the pump prime, it means the lid is leaking. Do you mean keep the lid off and pour into the pump basket?

When POOL mode starts, the priming cycle starts but does not complete. It continues to run at high speed instead of slowing after a minute. Through the pump lid, instead of seeing turbulent gushing water, I see only a bit of water coming in; the chamber does not get full. There is no suction...

I appreciate the help so far. If anyone has suggestions on where to go from here, I would be grateful.

In case the info helps, looking through records, I just discovered the previous owner self-installed a new pump motor in 2021. My best guess is the previous pump was about a decade old.

Reached in around the impeller and could not feel any debris. Pump lid O-ring is good. Turned MPV to Recirc. Same trickle in the check valve window, no movement in the skimmers, and no movement at any jets this time. Ever since I noticed a problem, the area around the pump has been very...

When I say waterfall, I guess I just mean spillover. Sorry about my limited terminology. The label on that return pipe does say WATERFALL though, FWIW.

All four suction scenarios had the same result: - Noticeable return (water and air) out of pool jet closest to pump, no return out of other jets. - Small stream of water (stream about 1/4-1/2 diameter) seen passing through return check valve. - No movement of water in either skimmer in any...

Thank you for that explanation. Is the WATERFALL line (with its own valve) on the pool side after the return valve a make-up line? I have not paid attention to it and it has always stayed in the closed position as in the first set of pictures. I had family needs, but headed out to do some...

I will get out there in just a few minutes. Do you mind telling me about the design details that impact the return needing to be set at 50/50? If it was designed correctly, what would the return be set at?

No spa-side remote. Weir doors are down and water level in pool is very high due to rain (a bit coming out the overflow pipe). There is no sucking down the skimmers at all. In AUTO, POOL mode only shows the word POOL when the filter F is pushed; if filter is off, there is a blank below AUTO...
