No or very low water pressure?

Question

I have a rental property which used to have excellent water pressure. My tenant told me a few weeks ago that the downstaris bathroom was having some water pressure problems, but everything was fine upstairs. A few days she called to tell me that this is now affecting the whole house. There is almost no pressure at any tap in the house, either hot or cold water. There does not appear to be a leak anywhere. What could be causing this, and does anyone have any idea how much it might cost to fix. The home was built in 1976 in Middle TN, and is on a slab foundation. Thanks for any help.

Answer 1

Is this house on city (municipal) water service, or is it on a well. If it is on a well, does it have a pressure tank to maintain water pressure while in use?

With city water, contact the water department to see if there is a problem in the meter or the supply line.

With well water, the tank could have leaked the air pressure and needs to be recharged, or the air bladder could have failed! The well pump could be failing, there could be a leak in the plumbing from the well to the house, or the well itself could be going dry!

With a bit more information, I could try to give a better answer!

Answer 2

The results from the City will most likely be fine...due to the fact that the exterior faucets seem to be just fine...that means that water is getting through your water meter and it most likely isn't the problem. But with the City there; perhaps they can do a pressure check for you at the exterior faucets...if it's less than expected, it could flag a problem. I don't know if they'd come inside and do a check...I think that sort of troubleshooting may be a little outside of their services. One thing you don't mention is the age of your house. My house is over thirty years old. It has copper pipes throughout except where the pipe comes out of the wall. Here is what I found when I was trying to improve the flow at the kitchen and bathroom sinks. Under the sink; where the pipe comes out of the wall; the pipe was Galvanized (not copper)...I think this pipe is called a Teat...after taking this off I found that the pipe was corroding on the inside (it looked fine on the outside). The passage through the pipe was only about 1/8 inch. I replaced all of these pipes and improved the flow at all the sinks. I don't recall what material I used for the replacement, I'm may have replaced it with new Galvanized pipe.. If you find a similar problem...perhaps someone at a local Home store can suggest something.

Answer 3

Blockage or breakage. If its broken you might not see water stains, it might be going underground. Have someone test it at the gate (where you connect to the supply) It could also be blocked by rot, depending on the type of pipe, cast.
My guess is a break under the slab. Test the pressure at the source, and move towards the house.

Answer 4

first find out if water company is doing any work in area or any burst pipes in area maybe causing a dry patch or vacuume in main server. also check main feed outside of property make sure stopcock isnt faulty the problem stems from main feed outside property not internal waterworks
get water company to check pressure from main feeds

Answer 5

THERE SEEMS TO BE A CLOG FROM THE MAIN WATER
LINE> IT STARTS WHERE BEFORE THE LINE SPLITS
TO THE HOT WATER HEATER. CUT LINE & REPLACE.

YOR CAN RECONNECT LINES WITH SHARK BITE-FOUND AT HOME DEPOT.NO SOLDERING.SHARK BITE CAN WITH STASND 200-POUNDS OF PRESSURE
AND SNAPS ON

Answer 6

is the supply coming from the town or city?maybe the leak is under your front lawn or wherever the main comes from..good luck

Answer 7

i agree with the other answers, but, you might have a crack in your water line under ground..or roots clogging up the underground pipes..time for a plummer..
