I've got a Pondmaster 950 GPH model 02720. I'm currently using a 2" corrugated hose but plan on replacing it with PVC. The outlet is 3/4" NPT thread. The fact sheet states to use a minimum diameter hose of 1.5".

That seems rather odd to me as the outlet is 3/4 inch.

My plan is to connect 1/2" pvc to the pump and run it around the waterway with about 6 or 8 ball valve outlets so the water flows out in multiple places.

Do you think this is OK or should I go above 1/2 pvc? My main concern is harming the pump. If the only disadvantage to using smaller pvc is lowered flow rate, I'm ok with that.

Thanks for your help on this.

Here's the pdf fact sheet:

I'm going to run the CPVC around the inner edge of the aqueduct (the outer side has a railway track).

The config will look like this: I_________I_________I_______I________I ... with the outlets dribbling water into the Roman Aqueduct. The CPVC will be spray painted to prevent UV damage.

You should keep running the 1 1/2" pipe all the way to your last 1/2" opening
