I've got an old home (galvanized water supply, originally on well). A few years back the well went dry and burnt out the pump. I opted to go on city water.
The new water supply was a 3/4 inch pvc line (the utility says that is the standard in this area). When the plumber tied into the old system, he just connected in at the t leading up to the washing machine (about 15-20 feet from where the old well entered. This continued to the water heater, and all the other fixtures. Once past the kitchen sink, the galvanized pipe expands to 1 inch for some reason, (but this never caused any problem before), then t's to each bathroom. 4 hose bibs just branch off along the way.
Recently, the pipes between the new service and the kitchen sink have been obviously rusting through, and need to be replaced. I decided to do this myself, and for the time being, replaced the old (3/4 galvanized) from the point of entry of the city water supply to the kitchen sink with a 3/4 inch cpvc line.
The new pipe supplies the washer first, t's (3/4 cpvc) to the tankless heater, continues to the kitchen sink, then the old plumbing runs go from there to the bathroom fixtures.
Since replacing the pipe, my pressure has dropped considerably, even when only 1 fixture is running. There is no sludge in the lines, the aerators are not showing any sediment, the only thing that appears to have changed is that I replaced the old, mostly blocked lines with new cpvc.
I'm assuming that if anything, the inside diameter of these pipes is greater than what has been replaced. I'm wondering if anyone has got any idea for me.
1)Would bringing the supply directly past the washer to the heater, then kitchen sink....then back to the washer have any effect? Seems this would only be a possibility if the washer was running, yet the pressure is always low.
2) Can I alter the pressure significantly without a larger line from the municipal supply?
