Hello, I am building. 300 gallon rubbermaid stock tank goldfish pond with a separate 100 or 150 gallon tank for an anoxic filter with suitable plants. I understand how to calculate head (using a calculator online). However, I cant yet figure out the pressure loss given these two options.
1. Pump on ground with” piping going up and over the side of the tank and down to the bottom where there would be a retrofit bottom drain and 2” check valve. At the apex on top a 2” ball valve to add prime water. And a hayward lx leaf basket before the periha 25000 pump.
I-ball valve-l
I l
Pump<——-l. l—<checkvalve<retroBd
2.Placing a bulkhead fitting opposite the drain plug fitting. Connect that on the inside to a retrofit bottom drain(or not). And on the outside of bulkhead ground level with bottom drain retrofit.
check valve —-> strainer——> pump
Id prefer to stay with 2” as have full swing check valve and plenty of pipe and fittings in this size.
Thank You very much!
