Adding a Second Return
I have an oval pool 33'x 18'. The problem I have is that my water doesn't fully circulate, I always have more dirt on the opposite end on the pool skimmer and jet and there is a big difference in temperature because the heat doesn't seem to be equally distributed inside the pool.
I have 1.5 hp pump with sand filter and gas heater. I was wondering if my solution should be to add another jet at the other end of the pool.
But will I lose water pressure and will I lose heat from having extended my outside plumbing by 33 feet making the heat escape in the plumbing. What is my best solution.
Hi Alan. You are correct that you need to add a second return. A 1.5 HP pump needs two returns to get the best performance.
When installing the second return use a 3-way valve in the line so you can set the flow to each return. That way your first return can act as the main one with the second one being a helper and never getting the full flow, thus limiting any flow loss over the long distance.
Another consideration would be not putting the return all the way at the other end. Installing it ten to fifteen feet down from your first one would probably give you all the additional flow you need to completely circulate the pool.
