In response to Re: Whole House low water pressure
: House gets water supply from municipal water main about 300 ft from house.House and water supply line all new 7 years ago. About 2 months ago flow anywhere in house, hot or cold, started decreasing when a faucet or spigot is opened. It takes about 5 or 6 seconds after opening spigot for it to begin decreasing, and it tails off rapidly to almost no flow. Pressure is commensurate with flow. Water company replaced meter at street, no improvement. Conclusion is that a crimp has developed somewhere in the 300 ft of 1 inch supply line to house after observing a pressure guage that we placed at the black plastic pipe entrance to the house tail off as described above. Question: Can the time delay from opening a faucet to the start of decreasing pressure be translated into determining a distance from the house to start digging to find the crimp?

Bill have you checked your main valve? Is it a ball valve or a globe valve? If it is determined that you have a crimp in the line don't fix it, replace the whole line with sch 40 or sch 80 pvc. Why take a chance that another crimp may devolop later on?Dale Peck LMP
