Sudden Loss of Water Pressure
About a week ago we lost water pressure throughout the house and yard (sprinklers). Both hot and cold are affected. My house was built in 1999, copper pipes, we do have water softener (it was without salt for about 2 months), we use city water. The city checked the pressure at the street end and the pressure is normal. The guy tested the pressure in the backflow valve for the sprinklers and it is fine, but said the flow could still be low. He also said maybe the regulator is blocked, but the pipes to home land yard split before the regulator. So wouldn't that mean the flow is blocked before where the pipes split? The city guy said we might need to get a backhoe and dig up the whole front yard to "fix" the pipe, but he can't even identify where the problem is. Any ideas?? What type of professional would I call to find the problem??

If this were my call the first thing I would do is disconnect the water service line ahead of the PRV valve and see if I had pressure and volume up to the valve. Your problem will be solved by the process of elimination. Some where along the line you will find a point where pressure and volume falls off. Start at the meter and work to the PRV valve. Good luck, Tom

Greetings, I have a sudden loss of hot water pressure in entire house (all showers, washing machine, sinks, etc.) Nothing has been touched or replaced. We have a well and our 50 gallon hot water heater is new - installed Sept. 2003. I have been reading this could be 'air pressure' related but...
I woke up this morning and noticed a significant loss in the water pressure in my house. The water is coming out of the faucets at less than half it's normal pressure and the water going to our irrigation system had such low pressure that the sprinkler heads would not even rotate. I have zero...
Recently the pressure in both the hot and cold faucets on one bathroom sink dropped to almost nothing. We replaced the very old faucet with a new one but it did no good. We still have just the tiniest trickle out of both hot and cold. The tub and toilet in the same room are not affected. The...
A couple of days ago I turned on the water at my kitchen sink and it came out with the usual force, but then about 10 seconds later it slowed down considerably. This continues to happen on both the cold and hot water, but I have not seen this happen at any of the other faucets in the house. ...
Our shower recently began to act weird. One day we had to turn the single control knob much hotter to get the same temp that we did before. Now, about a month after that, we have to turn the knob even further, and we have lost a lot of our hot water pressure. The rest of the house seems to have...
