My 20x40 roman-end, steel wall pool is currently under construction. My concern is that my pool is not being installed with the proper size PVC plumbing and appropriate equipment.
My pool will have the following features:
1) 10 ft. wide entry with 2 jets.
2) 2 cozy coves; each with 6 jets.
3) 3 wide mouth skimmers
4) 3 returns
5) 4 arcing fountains
He is using 1.5 inch plumbing, a 2 hp Hayward 2 speed pump and is also adding a 2 hp Hayward pump to run the cozy coves. Is the 1.5 inch plumbing adequate? What will happen if he uses the 1.5 in plumbing instead of the 2 inch plumbing?
He claims that the wide mouth skimmers used only accept 1.5 inch plumbing and even if he used 2 inch plumbing, it would need to be scaled down at the point of the skimmers. Is that true?
He is installing a Hayward DE 48 filter. I think this is undersized. If what I think is true, what size filter should he use given the two 2 hp pumps. What will happen if he sticks with the de48?
Other than that, I believe the other equipment (salt water generator, heat pump) is appropriate.
I've never had a pool and am really concerned, so any advice or input would be greatly appreciated.
I just want a trouble free pool that runs efficiently. Thanks in advance.
