I am re-plumbing my equipment before replastering my pool. Just want to make sure my pipes are adequate.
My pool is about 24000 gallons. It has a combined spa and pool. The spa has 2" pipes on both return and supply. The pool has 2 skimmers which are connected to 1.5" pipes. The two 1.5" pipes then join to become a 2" pipe which goes to the pump. However, the pool return is only 1.5" while the spa return is 2". See the attached file.
1. Does it improve the water flow if I convert the short section of 1.5" pool return to 2" before it branches out to 5 wall jets. All my pipes are exposed, so it is not hard to change.
2. Most of booster pumps have 3/4" in/out pipes. Hayward has 1.5" in/out pipes. Since the pressure side of the booster pump will eventually connect to 1.5" pipe in the wall. Is it better to use a booster pump that uses 1.5" pipes all round instead of converting between 3/4" and 1.5"? I am wondering about water flow efficiency.
