Plumbing question

68sting · 04/15/2009, 09:47 PM

I may have imagined reading this but I thought I read somewhere to have a little bigger pipe feeding the pump then the pump will take. So for instance I would have a 1.5" pipe from my sump then reduced to 1" at the pump.

On the other end I would come off the pump returning to the tank with 1" and would I reduce down to say 3/4" to the two returns to maintain pressure. Does this sound right?

Thanks

no
I would keep slightly larger diameter feeding the pump, than the pipe going from pump back to the pump

I would not restrict the flow feeding the pump, but you can control the flow by placing a valve on tube leving the pump, and only if you want slightly lower flow

I think we might be saying the same thing.

The input on my pump is 1". So I should come out of the sump in to the return pump with say 1.5".

The output is also 1" on this pump so your saying to keep it 1" all the way even though its being split off to two returns?

Thanks

Normal= 1" intake then 3/4" return

Normal= 1.5" intake then 1.25 return

No, if the return is 1" then drop it to 3/4" then you split it, that'll work.

thanks for the info on the return side.

How about the intake side? Should it be a little larger so the pump is easily fed enough water versus it being the exact same size as the intake on the pump?

It will reduce strain on the pump and allow it to have more head pressure. It may even reduce running temp....

Usually the intake you use what the pump suggests.

All products can be modified to increase performance. I believe in pushing performance to the limit..... But that is just me.

Thanks for the input again. Anybody else want to chime in???

No offense bro. Was just answering his question about the intake side.
