Optimal PSI for house water
I noticed that my water supply from the street has a peasure reducing fitting on it. The preasure is currently set to 25 PSI and it has a range from 25-75 PSI. I am looking to install an RODI system, which requires water preasure of at least 50 PSI.
I have a couple of questions about this:
1) i have an old house with old plumbing. How much of a risk is it to increase the PSI to 50 or 60?
2) Is there an optimal PSI to set it to? Is it better off at this lower number (and I'll need a pump ofr the RODI) or is a higher preasure better?
3) The preasure gage has been on the pipe for years. Do they go bad? Should i replace the gage before increasing the preasure to make sure its reading correctly?
I'm thinking that this is also the reason that we don't allways get great water preasure in the shower upstairs, and that it takes forever for our washing machine and dishwasher to fill.
Thanks in advance for the help.
