Ok, so for the past two weeks i have been getting the place in shape and noticed that all the faucets/toilets had low water pressure... i just thought that the water main at the street wasn't open all the way and didn't mess with it. Get renters, and finally decide to go to the street to open it up all the way and i discovered that it is already open.
Here are some things i have observed:
- the dial isn't spinning when the water is off, so no leaks anywhere.
- the kitchen sink, bathroom sink, tub, and toilet are all exhibiting only a low-medium water flow (toilet takes over 2 minutes to refill)
- when i first turn on any of the faucets, i will get a normal high pressure flow for about 1 second, and then it drops as the built up pressure drops
- the washing machine cold water supply (2nd exit point in the house off of the main line) appears to have a normal high pressure flow.
- an outside spigot (1st exit point in the house off the main line), which branches off a few feet BEFORE the washing machine cold water supply, is exhibiting the low pressure issue
- the washing machine hot water supply appears to have normal high pressure
I'm stumped. Normal high pressure at the washing machine outlets indicate that the pressure is ok coming from the street. A second of normal pressure at the sink faucets before the pressure drops indicates that the lines aren't built up with deposits (otherwise it wouldn't flow with normal pressure for that first second, right?).
The most puzzling to me is why the WM cold outlet flows normal high pressure, but the spigot that splits off a few feet BEFORE it flows low pressure. If high pressure is going to the WM, it should be going to that spigot... i mean there is a shut off valve on the spigot branch, that i suppose could be bad (wouldn't think it likely but i guess its possible) but then whats the deal with the rest of the house?
Thanks for any advice!
