*The further away your taps are (example: the bathroom) the less water pressure you have. If you have a lot of trees around your property I suggest getting "Rotor Rooter" in to clean out your pipes. Especially in an older home the pipes can have all sorts of odd things in them, and tree roots are one of the worst. Also have your water heater checked out on a yearly basis. My bet is on the tree roots. *If the utility valves are turned on all the way, then check the aerators. They usually get clogged up with debris, and affect the pressure/water flow. Shower heads are designed to use less water, so you will not have much pressure because of the built-in restrictor. The info about the aerators is a good answer. I am in the drinking water business and have answered a lot of calls for no water or low water perssure when the only thing wrong were clogged aerators. Often the pressure is good, but the low volume at one or more spigots will make you think it is a pressure issue. Waterman
You have to undo the aerator at the end of the faucet and clean the screen or plastic water saver out. It will be plugged with sand or sediment.
No.
Yes! the water pressure in my house was very weak...when my hot water heater broke and it was replaces the plumber said that there were pieces of poly tubing broken up in the line. He said that the poly tubing used to be put in at one time to make the heater more insulated but that it breaks down after time and causes poor water pressure
Increase the pressure to 40 PSI
Possibly a pressure reducing valve installed after piping for first faucet, which would cause situation describing.
Most of the newer kitchen faucets have "flow restrictors" to limit water use.
Standard meter will suffice, need to know pressure from meter to house. Size pipe appropriately for gas pressure coming into house X distance to water heater. Gas company or plumber should be able to help with this calculation.
Mixer valve
Moen faucets are very modern and stylish. It is possible that they will have a great appearance to match your house. You can also look at Kohler faucets.
Remove hoses. Inject water into heater water output connection but be carefull not to use full pressure of house supply.
My wife wants to buy some kitchen faucets for our new house. Where can I purchase such items cheap in the US?
.In simplified terms . The slower water flow will pick up more heat than the faster water flowing through the heater. Tom H. HVAC proffesional, New Orleans
