How may turns on CSV adjustment bolt
« on: April 28, 2021, 10:03:24 AM »
I've just about got all my parts together for my new pump and the CSV1 install.  When I ordered it, I had it preset to 55psi.  I want to increase that to 60 psi.  I've adjusted the pressure switch (was preset to 45/65) to 50/70 based on the assumption that one full turn on the pressure switch is about 2-3 psi.  I know I can adjust the CSV1 after install, but was wonders is there a rule of thumb for the CSV bolt turns as relates to PSI increase.  I'm just trying to get everything set as close as possible before turning on everything and I could find my answer with the search.

One full turn of the adjustment bolt on the CSV1A is about 14 PSI.  A third of a round will bring it up 5 PSI.  Best to run a shower and set the CSV to what you want while the shower is running.

Thanks Cary.  I'll adjust a little and then dial in with shower test once it's all hooked up.
