Ran call for fluctuating water pressure throughout the home. Could not get this issue to recreate itself while I was onsite, water pressure on the well side is holding between 40-60 psi with no issues. I believe this issue is being caused by the 4 10 plus year old existing rain soft filtration systems that have never been serviced. Rain soft recently went out of business. They did send the homeowner information for another company to come out and service the units, they will be contacting them for the service. Put all 4 units in bypass for the time being, if the pressure fluctuates with the 4 units in bypass we know it’s not a filter issue and something else in the home. Also spoke with them about removing the rain soft units and installing water right units. They will make that decision after they find out what’s going on with the existing units.
