Water Pump
Hey y'all. We have a 2012 Forest River Shamrock 21SS Hybrid. We do some boondocking and I want to up upgrade the water pump. Can someone tell me what the flow rate is on the factory one, since I canno...

I had to replace our pump last spring and bought this Shurflo.
Not sure if it matched the old one's flow rate (this one is 3.0 gallons per minute) but I was not trying to upgrade the pump. I put in a 1.5 gallon pressure tank to improve the flow and help extend the time between pump cycles. We had one of those tiny RV accumulator tanks and I didn't think it helped at all. The larger tank does improve flow and eliminates drop in pressure between pump cycles.
I just noticed this is the old pump--I tried to rebuild it first. A closeup of the label seems to read 2.5 GPM and 45 psi while the new one is 3.0 GPM and 55 psi. Our RV is a 2002 so since your rig is newer, your pump is probably closer to 3.X.
