Well, We had someone come out and take alook....It was frozen somewhere from the pump to the house...It took a full two days until thawed out...Covered the pipe with an enclosure and heat lamp while we used a heater for the pipes coming into house...Finally full water flow by end of yesterday evening...what a relief! juanital

There was a house for sale across the street from me in 2008. It was one of those project houses...needed a total gut job. A nice couple bought it as an investment house. They toiled all spring and summer fixing up the house. The did a fabulous job. New hardwood maple flooring, real plaster walls (instead of drywall--they wanted to stay true to the age of the house), fabulous wood trim. It was an extremely nice DIY renovation. The DIY couple, rented the house out in August to a 20 something couple that worked at a local university. All was good. The young couple fit in our neighborhood great and they seemed happy. Christmas 2008. The young couple goes away for 2 weeks to visit family. When they get home after New Year's they find the house completely flooded. The plaster walls and ceiling have fallen down. The lovely maple floors are in waves. All of their belongs are ruined. Mold is growing up the walls. They go around to the neighbors asking for help. Young couple has no real tools, or even a decent mop. The entire neighborhood pitches into to help them out. We give the young couple a place to stay. The landlords finally arrive...having to the longest 10 hour drive of their lives to get back and see the mess. Turns out a pipe burst in an upstairs bathroom because it was on an outside wall and wasn't insulated correctly. The house is deemed uninhabitable until repairs are made. The young couple finds a new place to live. The landlords start the fight with the insurance company. Their claim is denied. They get a lawyer and continue to fight. Eventually, the claim is accepted. The landlord couple spends the entire summer of 2009 doing what they just did a year ago. A new young couple moves in August 2009. But this year will be different because the landlords installed an automatic shut off leak detection valve. They told us it was pretty expensive but it sure beats doing the rehab yet again. Now, when we go away, we turn the water off at the main, open the faucets and flush the toilets. We have our heat on and have neighbors check on our cat daily. We don't drain anything, but at least if something bursts the water can't just continue to run. So far so good. I will never forget walking into the house across the street last winter. Seeing the plaster walls, insulation and everything from the 2nd floor on the 1st floor with mold growing up the walls was one of those visions I'll remember forever. I'd really like to get one of the automatic leak detector valves for my house too.

You can always shut off the water at the main and work on it. Just have a bucket to handle the water that will drain from the pipe for a minute or two. In fact, if you do that, you can replace the frozen valve at the same time as it probably isn't going to get better... :-)

L'Anda Johnson You are correct, there is something wrong from the street up to and including the PRV. So let's talk about odds - places to look: The most likely places for a restriction is someplace the pipe narrows down already. Those places would be: 1. The shutoff valve at the street 2. the shutoff valve before the PRV 3. The PRV Clearly you want to be sure that the valves are all the way open as Weedmeister suggested. You may want to close the valves you have access to and re-open them (again, only the valves upstream of where you measured your pressure). Sometimes if there's significant crud blocking the valve you will feel it as you close the valve. Closing the valve can sometimes break that up and cause the crud to flush through when you open it up. I know you want to rule out the PRV because you replaced it... but if the valves are open THE most likely place for this problem is at the PRV. More specifically, there is a screen on the PRV inlet that can get clogged from debris because this is a new line. Be sure to rule out the screen on the PRV - simply because that's the most likely source of the problem. You said that this was new construction. Was the water service line new (new development) or was there a house there previously and you re-used the water service line from the street? This is what a PRV screen looks like:
