I had the supply line to my house break, it was a 20 year old piece of polybutylene that ran from the water meter to the copper connection to the house. I dug a new trench, ran 3/4" PVC, turned on the water and evrthing was fine.
Three weeks later I find that the copper conenction to the house somehow got a pin sized hole poked in it. So I fixed that, turned the water on, no leaks, the leak detector isn't moving, everything should be back to normal...
but
now we have noticed a drop in the water pressure in the house. It used to be that we could have a two or three facuets turned on before we noticed a drop in the pressure but now if we even have two on there is a noticable differnce. So I am confused as to what could have changed? All I did was fix the leak in the copper pipe. I used the same size pipe and everything, there shouldn't be any change in the flow into the house.
Any ideas?

sometimes debris can find a place to settle and restrict flow.

I agree, theres probably some debris in the aerator, faucet, or supply stops.

I know how to check faucets, but how do I check the other two?

Their not as strong as usual either I think, but they get their water from the lines running in the house and dont have their own branch.

Debris in an aerator, supply stop, or faucet, would NOT cause a reduced pressure ELSEWHERE when additional faucets were used. That can ONLY happen when something is obstructing the main supply line TO those fixtures. But, without knowing more about the piping arrangement, we cannot tell you WHERE that spot could be.

I live in a town house which make the arangment simple but accessing it difficult. I have a main supply line that come in under th slab in the water heater closet and tees into the tank and the runs to two bath rooms (one upstair, one down stairs, kitchen (down stairs) and two outside faucets(one front one back)
When I was repairing the line I made sure that I kept the lines out of the mudd as much as possible and when the end did get dirty, I wiped it off with a rag. The only this i can really think of is that either some mud (not likely) or some pipe glue (perhaps) is floating in the line somewhere.

IF opening multiple faucets affects both the hot and cold, then the problem is before the pipe gets to the water heater. If only one of them is affected, then it is in that system after they separate.

I believe teh problem is before the water gets to the tank as it doesn't matter what faucet, cold or hot I am using. If I have more than one thing on in the house, the WP drops alot.
I have called the city to ask them to check the water meter/shut off valve just to be sure it is ok. I had to take the meter off when replacing the line because it would not shut off completely at the valve and water was trickling into my line while i was trying to glue. It 'seems' to be working fine but you never know....
