Dolphin 3000, in and out different sizes?

[Anonymous]

I am going to add a Ampmaster 3000 I picked up to my system. The person I bought it from changed the 1.5 in and out to a 1 inch out and 1.25 in. Any reason besides reduced flow that I should leave it as is?

TIA

Sounds almost exactly like an option that Dolphin makes for their pumps.

You probably already know this, but just FYI, according to the manufacturer, going from 1.5" down to 1" plumbing results in like a 40% loss in flow.

That is true if you go to a single 1". I think if you tee off to (2) 1" pipes you only get the same reductions as with any fitting. I may be wrong.

I took it from Righty's post that the pump is setup as a single 1" outlet.

Doh, I read it wrong.

Louey,

Which option are you talking about?

Chris,
I know about the loss, but if I can get the water movement I want without having to spend money on new fittings for the pump I am happier!

I was referring to the one pictured below. It is basically a tee, which was what I thought a read in your original post. My bad.

You should able even happier if you know that the pump will also make your heater works less.
