Hi all.
New to the forums. looks like there is some good info here.

hope I'm posting this in the right place.

I am currently in the middle of building a new pool in Spain. The concrete base and the walls are complete. with 1.5" pipes in the walls for the 3 inlets & 1 Vac point, Skimmers also installed. main drain & light housing also installed.

Ive had a discussion with the pool shop in the local town. who did a rough sketch of the skimmer and inlet plumbing.

I have a couple of questions..

The inlet design by the shop looks correct to me as it should give equal flow to all inlets.
The design for skimmer also looks ok BUT I'm concerned that if I were to get a blockage in the single pipe. I would loose the use of both skimmers?

Would I be better to run 2 seperate skimmer pipes back to the 3 or 4 way manifold with a valves on each pipe?

Should the vacume pipe be run straight to the manifold isolated with a valve in the pump house or can i connect it via the skimmer?

I can't seem to add images here.
So a link to photobucket of the 5 days of pool construction so far.. ... ing%20Pool ... ool%20pics

Hello, if I may offer a suggestion. The following plumbing diagram shall give you the best of all worlds, enabling you to independently control each pipe going into the pump, or enable you to utilize all three lines into the pump at once. Whichever combination you fancy.

I do agree on the notion never to utilize a "T" connector underground where they both come into one pipe. That could open the door to complications. Utilizing this diagram, plumb the valves close to the pump and filter area. No manifold is necessary.
