Dual Speed or a Variable Speed for a plain Jane pool.

[Lip Out]

It looks like whomever plumbed the heater took some short cuts. You could fix this pretty easily by dropping the 3-way valve to the same the level as the heater exit so you could eliminate a 90 and the coupler but you would probably need a new 3-way valve to upsize the branch line. This could be a future project at some point since it is completely independent of the pump and I would only redo it if you plan on plumbing in the cleaner line.

As for the pump

Hey Mark, I have a few questions again. When you say they took short cuts and I should lower and remove the 90*, is that because (on the pressure side) the more 90*s you have you lose pressure? Or are the short cuts more extensive.

I went out and measured the pipe again. The suction side is 2". The pressure side to the spa (I believe it goes to the spa) is 2". The pressure side to the pool is 1.5". Maybe be vice/versa. Those are going in to the ground. Will the 1.5" be an issue when plumbing for the Intelliflo? Also, it has 1.5" going to the filter. I have never looked under there, will I be able to take 2" to the bottom of that type of DE filter?

When I re-plumb this I want to do this in one shot. So, I was looking around for some plumbing schematics, and I believe this one will work. I am correct in my thinking? If it is, what is the purpose of having 2 valves for the spa, especially the "Spa Make-up" valve before the check valve? What is the purpose of having the 2 directional valves for the Spa?

Thanks again for the help.
