Pool Plumbing

[PSCel]

I assume the pipes leading into my pump at the front are the skimmer and spa return, but what is the pipe at the lower left with the blue closed valve (which has been closed since built)? My installer didn’t leave me any diagrams, didn’t label pipes, and gave me a cursory training sesh mostly focused on how to set things up for spa, pool, and cleaning. Thanks for your input!!

Tell us more about your pool and a couple of pictures of the complete equipment pad. It can be several things possibly a suction side cleaner but that's only guessing.

Sure thing, it’s a Pentair salt system, here are more pics. There isn’t anything that looks like a vacuum inlet but there is what looks like a regular 1” jet that doesn’t actually jet and isn’t marked on the original plan as a jet (or anything), which is part of the mystery I’m trying to solve.

Is there anything similar to this about 6" or so below the water level (or an open pipe)?

Do you have a suction side cleaner?

 

[PSCel]

Nope nothing like that, there is a curious jet that has never jetted but it looks like a jet with a directional screw in faceplate. I ran a snake up it and blew water via a garden hose thru, it dislodged some debris but it still has no output when the pool is running.

Open the valve - just a little - and CAREFULLY check for suction at that port.
How do you vacuum/clean the pool?

 

[PSCel]

I’ll give it a shot. We vacuum via the skimmer, remove the basket and plug the hose into the suction hole underneath.

Not safe if you don't have a catch basket in line. THIS

Hmm don’t want to mess anything up for sure. Judging by what I am seeing plumbing wise and finding on the internet pointing to initial installations leaving just a jet port where a vacuum port is intended to be placed, I have a sneaking suspicion that’s what the mystery piping and port are indeed. Thanks everyone!

Did you open the valve a little (with pump running) and check for suction at that port?
Easy less than 2 minute test.....
