Need more pressure in new home?
I just recently moved into a new home and our water pressure is horrible. Everything just trickles compared to my last house. Is there anything I can do, is it possible to adjust the incoming bell shaped valve to increase pressure through out the home?

Also I noticed on this homes hot water heater there is a small blue tank that comes off of it. What is this, it looks almost like a mini propane tank.

That blue tank is your thermal expansion tank, that should not be taken off, its designed to cusion air from thermal expansion, so you want see drastic changes in pressure and it also eliminates the chance for warm water to backflow into the cold system. But, I dont see how your just taking it off....?

Check all faucets for clogged filter screens. It may be your only problem.

I wasn't going to take it off, lol. I was just curious as to what it was!

As far as clogged screens? How could one clogged screen on say the kitchen faucet cause all the other faucets to be slow?

I am thinking the incoming main pressure is low, as its that way through out the entire house. I remember the water company turning it up some at my old home and commenting on how it would help us out. I was just not sure how much to turn mine up, or if its a good idea. My last home would have some banging pipes when the water would suddenly shut off, which I figured was from the higher pressure!

Yea 60psi Is the safe max that you really should run. Some even run lower then that. Anything over 80psi by code is required to have a pressure reg. Altho some people run at 80psi its not good for the pipes and valves. Check your pressure with a pressure guage. They sell them at the big box stores for like 10-15.00. all it is a 100psi water guage that screws on to your outside hose spicket. Screw it on like a garden hose and open the valve. It will tell you where your at. Less then 60PSI you can bring it up to that. Anything more is not recommened.

Also dont forget poor flow causes low pressure. How old is and what type of plumming is in this house?

In old pipes sediment builds up and slowly fills all the screens in every faucet. Also if the water was shut off for a period and then turn on, sediment from the well bottom may flood the system. So I still say check all screens. This pressure drop could have happened over time and the old homeowners would not have noticed a slow decrease.

Thank you very much for the pressure gauge suggestion! I will pick one up at Lowes this weekend and try it out. As far as the age the home is 4 years old, and has standard copper piping.
