I called South Sumter, our water provider, who assured me their water pressure was okay. I ended up having a plumber install a pressure regulator below the filter to insure against excessive pressure. When they changed my filters last month there was indications of stress in the filter housing that had been leaking.
One other thing to note. I called Mike Scott Plumbing to install the pressure regulator. They flat refused to do it. I ended up talking to the guy who schedules the repairmen, and he said no. Ross Plumbing did the job for about $400.00.

A pressure regulator will only control the pressure in one direction. So, if you have a pressure regulator installed on the incoming side of your house, it will control the pressure entering your house, but it will not control the pressure that can build up inside your house as a result of a defective expansion tank on your water heater. That is why your water heater has a pressure relief valve on it to relieve the pressure if it exceeds 150 psi. This can occur if the expansion tank is defective and you have thermal expansion as a result of using a lot of hot water and then shutting off all faucets and plumbing fixtures. I would suggest that you buy a pressure gauge from Amazon for about 10 dollars, so you can easily measure your house pressure by screwing it onto an outside hose bib. You can also place a plastic cup under the relief valve discharge pipe to see if any water is being released by the relief valve. However, I am surprised that the Nova canisters are not designed to withstand an occasional increase in water pressure to 150 psi.
