Calgary water pressure

OR ... you could .. I dunno if this has been suggested or not yet, but if not .. my suggestions is .... bypass the regulator for your RO/DI and leave the rest of the house on the regulator!

Rak! Polly want a cracker!

In Vernon my outdoor faucets are on City pressure (measured around 120 psi static and 100 with faucet on) and I have a PRV inside the house to bring that down. I didn't like the pathetic pressure at my kitchen sink, need a little more oomph when rinsing stuff, so I looked up the info on PRVs and adjusted mine so I have just under 90 psi for the indoor stuff. It drops to about 86 psi and holds relatively steady around there whenever any tap is running. Not sure what type of regulators some of you are referring to, maybe some are fixed pressure, not adjustable and need to be bypassed entirely if you want more pressure somewhere. The PRV however is fairly easy to adjust and I believe even at full throttle, limits the output pressure to a pre determined value depending on the model you have. A wrench, a pressure guage and you're in business. The PRV has a strainer in it as well, which should be cleaned periodically.

I believe my PRV is a Watts Series 25AUB-Z3. I found a pdf document online with installation instructions etc... Great info in that file including different installation options, typical, series, parallel....

EDIT: Just checked and confirmed I have a model 25AUB which is apparently adjustable from 25 to 75 psi. Makes me wonder how I'm getting better than 80 psi downstream. Either inaccurate guages or surges exceeding the 75 psi limit??
