Before I start, thanks everyone for any suggestions and ideas you may share.
I am new here, new to owning a pool, and it wasn't the smooth start I expected.

This is the last 3 wks summary, but I will keep it short.
A local company opened our pool, shocked it really good but in about 2 days we lost 2 inches of water. Then the water loss stopped when multiple returns were still under water, one was half way (will later be identified as the leaking one) and below the skimmer line.

This is a salt water pool : vinyl, rectangular, with 2 steps to enter on the side. Hayward salt water filtration, with Hayward EcoStart variable pump. There are 4 returns in the pool. One on the deep end side, 2 where the steps are, 1 across from the steps (basically 3 on the shallow end).

Basically how it looks like. RF is where they said there is a leak and put a rubber end in it. One of those black ones.
Result : No more leak.

Then we notice : the jet (return) on the deep end doesn't work anymore, no water coming out of. When I put my hand I feel nothing.
Days later we notice : filter pressure gauge reads 0psi in low speed (1750 rpm), 4 psi in high speed (3750 rpm)
We still can see water sucked in from the skimmer and the pump seeming to work fine.
Now we have come to a point, we seem to have lost the return across from the steps as well. We don't feel any water coming out of it.
Pressure gauge is reading 6-8 psi on high speed. (we just recently tried to vacuum the deep end) - maybe we did something?

All in all, we seem to have an extremely low psi reading, only ONE return working.

Is that OK to cap a return like that? Should we expect the other returns to stop working?
is the low pressure reading due to a faulty gauge? (I ordered a new one, will install in a couple days when it arrives)

I am all ears.

Thank you everyone.
 
Show us some pics of your pool and your equipment pad...

Just for reference with a VS pump, running at a low speed, along with a large filter, can often result in very low filter pressure, which is not a bad thing...

We need to understand what you have and a few pics will be better than thousands of words...

Thanks,

Jim R.
 
Thanks for the pics.. I am somewhat confused by your post.. Let's see if we can figure this out, one problem at a time..

Please tell me just about the leak, who found it, what they said, and what do they plan to do about it, if anything.. At this point lets forget about the pump and filter pressure.. The picture of your pool shows the pool to be full...??

Please double check that you Multiport valve is in the Filter position and that no water is coming out of the waste line..

Thanks,

Jim R.
 
Water is full, yes.
the technician who came to open the pool mentioned he remembered a leak on that particular return. but didn't do anything about it. he called his office, had a chat for a while but left everything open. I didn't think much about it then.

in a day or two, we noticed we were really losing water, we called them up. Meanwhile, leak stopped (halfway through that return) they came back in about 5 days. When we werent home. put the rubber plug. not sure what else they did.

Then we added water. And since then it has maintained its level.
 
a bit more background :
- sand in the filter has been replaced couple years ago apparently.
- they backwashed during opening it was really clean. I also did again yesterday, and water was a cloudy looking, but not dark. after about 3 minutes and stopped and reverted to "Rinse", couple minutes then "Filter.

Last couple weeks we have also been trying to get water chemicals in check.
We did one round last week. got it tested. was still quite off, now just finished the 2nd round of chemicals.
 
Update this morning,

Last night as I was taking pictures for Jim, I was also reading the manual for the pump and I believe the area that you can reach in after removing the basket is where the impeller can collect debris. There WAS debris there which I removed with my finger as best I can. It is a small space anyways and I think I did an OK job there.

I was so frustrated I didn't run the pump last night.

When I started it this morning, the "one" return that was working spewed out dirt for about 15-20 seconds, and the other 2 that were dead came back to life. I put on a skimmer sock, started running the pool on high rpm for things to circulate and hopefully clean.

I forgot to check the pressure gauge though.

Could that be the end of our troubles?

(I still want to come back to that leak and see if it is right at the end of the return, similar to what is in this video :
)
 
So that accumulation before impeller was the culprit of 2 returns basically not getting enough water flow. Water pressure was so low I guess that It couldn't push it any further than the first return (assuming that one is the closest in how the pipes are built)

I am curious to see what the gauge is going to read...
