Iím still getting what I like to describe asĒ A dribbleď out of the shower head. It is marginally adequate to take a shower. With the city water flow selector switch set up and the regulator set between 52 and 53 psi, it is similar to when I use the ShurFlo water pump, and it has a cut off at 55 psi. My next step I suppose, is to set up a PSA gauge on the end of the shower hose to see what pressure I am actually getting there. I should probably also measure the flow of water that the pump is putting out. The pump label says three GPM, and I would suggest that that amount is unlikely based on what Iím seeing at the showerhead. Am I being too anal about this, or should I just go get a hotel room?
Measuring your water pressure at the shower hose will be a waste of time, it will be the same as the pump output or the city water with no flow. (Ask Pascal).
Get a 2 quart picture.
Get your stopwatch app ready on your smart phone.
Go to the kitchen sink and measure the time it takes to fill the picture.
Remove the shower head and do the same thing from the shower hose.
Now do you have a shower flow problem? Or is it the same as the kitchen sink?
No difference? Put the shower head back on and measure again.
