Mak 4 and 1 1/2" stand pipe question

[kari]

Kelly;

I haven't tried that pump before and nothing beats trial an error experience. If you are in a scary situation, I can calculate the required ID of return pipe for you. However, I would need you to provide some plumbing info (eg. materials, fittings, lengths and sketch of plumbing with dims) and a copy of the flow diagram for the pump in question. The easiest method is refer to someone else's setup with the same pump and similar plumbing and apply a safety factor that you feel comfortable with. Or just apply a huge safety factor and be done with it. An over flow that is too large can not be a problem IMO yet the opposite can be painful.
Anyway, going beyond the Blah-Blah, it is better to overkill the overflow for future considerations such as added circulation. Don't undersize!
