      PVC Reducer

      I'd like to reduce pipe size but which is the better fitting to use? One must have less flow restrictions, otherwise it doesn't make sense in having two different fittings that serve the same purpose.

      I found a Fernco shaped just like one of them, but these can possibly fail in pressurized settings right? The line I'm reducing is sucking water from the pond to the pump rated at 3000gph

      I have fernco reducers on my lines from pond to pump. One has been there for 3 yrs and the other 6 yrs with no problems, both pumps are 4600 gph.

      Never use Fernco's on the outlet side of your pump. I have seem then come off.

      If you are concerned with drag the center one will do.

      It appears the one shaped like the fernco is not PVC 40 but DWV and should not be used in pressurized settings. ricshaw, you're never had any problems using this one on your plumbing?

      Never had a problem... the pressure is not that high with most Koi pond pumps.
