Best Use of Shut-Off Valves

Now this could go horribly wrong Swimdaddy, so please take it as a discussion not a criticism.
With a 1.5hp pump and only an 18" filter a 90 deg in the return line may actually help slow down the flow a bit in your case which will aid the filter in removing the dirt etc better. I am all for saving electricity and therefore hard earned income so I try to avoid all 90 deg elbows, if an elbow is used I usually replace that with a 90 deg bend. I get away with using only 0.08 Hp to run a 12000 gallon pool.

Totally with you, purchased my pool BEFORE I knew anything about pools, and I still don't know much but am constantly learning. Until my pump wears out and I can look into getting a better one, I use a valve between my pump and filter to regulate the filter pressure for better filtration, which works pretty good. I am also "kinda" looking for a bigger filter tank that I can put my current hayward valve on.
