City water pressure and volume question
 
It seems ever since a developer turned a single family house into a row of townhouses my water pressure has dropped. I spoke with a couple of my neighbors and they have the same problem. One neighbor had their water main replaced and said it fixed their problem, but I don't know to what extent.

I have about 30-35 psi at my spigot which is about 10 feet from the meter. I can barely use 3 appliances at the same time and notice a tremendous drop with the sprinkler on.

I was going to ask my neighbor if I could see what their water pressure was before I called someone in to install a new main. A friend of mine borrowed my guage and measured 70psi a few towns over.

1) What is a reasonable psi and how many gpm?

2) If I installed a water pressure booster pump (cheaper than a main) would the volume affect the performance?

3) Besides checking the gpm and psi, what else could I check?

Thanks

What size pipe do you have coming into the house?

How far is the house from the road or water main?

What size are the pipes inside the house?

1" coming in to the house

30-35' from the inside water meter to the street

The pipes inside start with 1 or 3/4 then gradually work their way down to 1/2. In fact, I can see in the basement that before any pipes leave the basement area they are 1/2".

Also, the house has 2 1/2 baths, clothes washer (on the 2nd floor), dishwasher. 2 story about 2200 sq ft.
