Plumbing Help

[Schnozz]

So, I'm ready to set up after my slab pour, equipment pad pour, wiring and my recent Pentair purchase. Kitchen remodel has dragged on a bit, but now we are ready for the pool.

I've attached a simple plumbing drawing. Does the set up look right? Did I forget any other components?

Thanks in advance......

S,

I suspect it is just a typo,

But the sequence is ... from the skimmer/drain to the input of the pump, then out of the pump to the filter, then out of the filter and back to the pool through your returns....

Make sure your pipes do NOT come up through the concrete...

Thanks,

Jim R.

I don't think you need a three-way on the returns, unless one leg feeds a pressure cleaner or a slide or waterfall.

 

[Schnozz]

JIMRAHBE: I've adjusted the image to reflect more accurately the flow of water

Richard320: You are correct....Do I need a two way at the pool or is the two way at the filter OK?

 

[Richard320]

It doesn't really matter. It's just to stop flow so you can open the pump basket. Wherever it fits best. You might lose less water on opening the basket if it's closer to the pump.

Do I need check valves anywhere in the supply or return piping? Would it be wise to add a coupler at the equipment end in case I had to remove a piece of equipment? Do I need two way valves at the pool end along with three way valves?

Is there anything I am overlooking?

thanks

Bob,

I see no reason for any check valves...

Personally I think it should be illegal to install a pump without using pump-unions...

They look like this and have an O-Ring on the threaded side..



I don't see a reason for the two-way valves as you already have a three-way valve on the same line.

Thanks,

Jim R.

Alright! Pool time! Nice to see you back in action.

 

[Schnozz]

Pooldv: Yep, I'm baaaaaaack. Here come the plumbing wuestions

JimR.: the connection on the Pentair pump/filter are 1 1/2" while the plumbing from the equipment to the pool is 2". Is there a union that will do that or do I use a reducer out of the union to the equipment?

bob,

I would get the 11/2" threaded unions that fit your pump and then add the adapter on the plumbing side..

Thanks,

Jim R.

 

[Schnozz]

Oh, so the union connects directly to the pump, the adapter comes after that. Vunderbah!!!
