I want to test my understanding about pump size and line size with some of the "forum experts" and get some feedback from others about this...

I just had an 18x36 IG vinyl liner pool installed and the pump and line size is different from what the sales person said...

What got installed is:
-- 1 hp sta-rite pump
-- 1.5" plumbing
-- 300 lb sta-rite sand filter
-- sta-rite heater
-- the filter/pump is about 35 feet from the water
-- 3 return lines (one deep for better heating)
-- 1 skimmer
-- 2 main drains

The sales person said we would get 2" plumbing & 1.5 hp pump (the contract says 1.5hp pump, but does not specify plumbing size). The guys that did the work said they always use 1.5" plumbing.

The question for the forum is, should I complain to them and if so, how much of a big deal should I make of it? They may offer to swap out the 1.0 hp pump for 1.5 hp, but I don't know if I would want that.

From what I've read in this forum it seems like what was installed is good and that going with a pump that is too big can waste electricity and force too much water through the filter making it less efficient. It just bugs me that what was installed is different from what the sales guy said. The company is a very reputable company and has been installing pools for 35 years.

Opinions please.

Thanks
