    What have I got myself into

    Hello all. I'm new to TFP and one year into pool ownership. And boy have I found myself in a bind. My pool is 13,000 gallons and has 1.5" plumbing with a sand filter.

    I needed to replace my pump (old one was making an aweful whine and was leaking) so I purchases a Hayward EcoStar Variable Speed Pump with SVRS. At the same time, I figured since I had to do new plumbing, I'd get a salt water conversion and purchased a Hayward Aqua-Rite T-15. After ordering this and receiving the Aqua-Rite, I was told that the pump was on "extreme backorder". So I then purchased a Pentair IntelliFlo VS pump. All of which is 2" piping, but I was told by the sales agents that I just needed a reducer and it would be good.

    So I had these items installed by a master plumber and all seemed well, but then I noticed a leak in my valve housing. So I ran down to the local poolstore and paid a fortune for a new valve. I got that installed and this one started leaking too. If these weren't professionally installed by a plumber I'd think I overtightened the threads. It seems that the pump creates too much pressure for the valve.

    So my thoughts are that maybe I should purchase a new cartridge filter, thus alleviating the need for a valve. And with 2" couplings it should be able to withstand the pressure from the pump.

    My ultimate goal is to run the pump 20 hours a day at 750 RPM with a 30 minute burst at 1400 RPM to capture the debris in the skimmer. This will turn over the pool a couple of times and create enough flow for the chlorinator to generate.

    Am I way off base? Am I just out right hosed?

    Any input is greatly appreciated.

    I've attached a photo for plumbing references (if needed).

    Thank you in advance for your help!

    If there is a leak, the plumber did something wrong or one of the parts is defective. The pump can not produce enough pressure to damage the plumbing or cause a leak.

    It is leaking from the actual seam on the valve where the top and bottom were connected from the factory. One valve leaking and I would agree that it was defective, but it has been two valves in the exact place. I know that I used to only have a 3/4 hp pump and this new one is up to a 3 hp. I have throttled it back by setting the max RPM's to 1900 instead of the 3450 default.

    Are you suggesting that I try a third valve?

    By the TOP do you mean where it is screwed together. If so remove the screws- apply some silicone lube to the O-ring and tighten back down. These valves should handle much more pressure.

    It's where the seam is in the plastic. Where the two plastic pieces were matched in the form from the factory.

    Can you show us a pic of the valves (or at least a brand and model number)....I don't see any in the pic you provided.

    It sounds to me like you are missing 0-rings but impossible to tell without some description of the valves.

    The valve is a Hayward SP0710X62 Pro-Series Vari-Flo Replacement 1-1/2-Inch Control Valve Assembly and it is leaking from the inlet valve that is fed directly from the pump.

    I've attached a pic showing where the leak is coming from. And yes, the sticker was "obeyed".

    It certainly looks cracked to me. If you look at the first pic you posted, it looks like the piping is in a bind against the salt cell. That will cause problems itself. Even to the point of cracking the inlet port as you show.
