ok.. I just found out that my return pump runs about 600gph but my overflow only runs about 300gph..(I think) since it says PF-300 on the model.. anyways is there anyway I can balance this thing out?.. or is it ok that my pump is stronger... I have heard of people using valves but I read on most sites that its not a good idea to use it as it should always be fully open.. Thanks in Advance!!!!!
One thing about your pump is that it might be rated that but by the time you figure head pressure and any bends in your plumbing then you are not going to have that much pressure. You might find them to be close anyway.
I cant find that one but I`m thinking 600 GPH at a 4 ft head I would think it would be close to what your overflow is. Anybody else have any ideas. I`m not the most technical on the subject of pumps. Somebody correct me if I`m wrong.
anybody?... still scared to try it out.. and waiting for the U tube I ordered to make it work!... should I add more tubing to be safe? or is 4 ft fine... how much GPH should I have for a 300 gph flow? TIA
Put a plastic valve in after your pump. If the overflow can't keep up with the pump, you can close the valve a bit and slow down the return flow.
4' of tubing is fine, you just don't want lot of extra tubing for the water to flow thu and add to the head pressure.
