I decided to improve things further by adding a pressure gauge. I fussed around with setting the pressure on the pump before. The gauge I used for that was attached to one of the hose bibs. I think adding a gauge closer to the pump will be better. It'll certainly be easier to make future adjustments.
I found all of the parts that I needed at Lowes.
- 0-60 psi pressure gauge (the pump is supposed to range from 30-50 psi).
- 1/2-in x 1/4-in Threaded Adapter Bushing Fitting
- 1/2-in slip x 1/2-in fpt PVC elbow (I can't find it on the web site to link to.)
- 1/2-in PVC tee
I plugged the pump back in and everything worked just as I hoped it would.
I was able to see the pump kick on when the gauge fell to 30 psi. Unfortunately it shut off just under 50 psi. I know I had it shutting off just over 50 psi previously. That was with a different gauge at a different location. I'll have to try to adjust it a little higher sometime when get a chance. For now everything seems to be working fine.
I've already used almost 300 gallons of rain water this year.
