Comments on How to Troubleshoot Low Water Pressure

I found my low hot water shower pressure problem to be a clogged filter on the end of the hot water pipe where it meets the mixer. The shower head (rose) was unscrewed, the plate and other fittings repmoved to expose the hot and cold water hoses meeting at the mixer in the wall.

My toilet has low water pressure. What can I do to troubleshoot issue?

We have low water pressure at our outside faucets. When we turn on the faucet to use the hose(s), there is a "whining" noise we hear coming from the water lines under the house. We get low pressure from the spray nozzles on the hoses. How can we check and fix this solution and/or boost it? The pressure in the house seems normal. The showers could use more pressure but that is probably from the shower heads.

LISAINCT64, have your plumber check the dip tube on your water heater. This carries the cold incoming water to the bottom of the heating vessel to be heated. If it's broken, you will lose hot water rapidly during use as the incoming cold water dilutes the hot water at the top of the vessel. The good news is: it's a very cheap repair (a new dip tube is only about $4.00 at a hardware store). As far as your kitchen faucet is concerned, I think you have an obstruction in your faucet, despite what your plumber says. It's probably right in the supply lines just before the mixing valve on your faucet. That would account for the split second of normal water pressure you have followed by the weakened pressure.

My water pressure problem occurs when I flush a toilet while the shower or sink faucet is running. The shower or sink water pressure goes down to a trickle. As soon as the toilet tank refills, the pressure is restored in the sink/shower. Where do I begin to solve this?

My wife and I bought a home that is older. The 40 gallon discontinued sears water heater finally kicked the bucket. We had a new one installed and the water pressure is still great but in the tub. There is now only a trickle from both the hot and cold. We are not sure about what the repairman might have got in the lines or if that would restrict the flow just to the tub. any help would be greatly apreciated. thanks.

What is the typical diameter pipe at the water supply (street curb)? Mine looks to be 5/8 outside diameter which is likely 1/2" ID if copper type M. I called the california water supply Co and they said it was standard and the pressure read 50psi on the out side hose bib, which was common he said. I measured a house about 1 mile away same town and it was 3/4" Copper piping-hmm.

After having been handed down my wife's parents 1950's house, I've learned to live with the weak water pressure. Thinking that the problems lies with the old pipes I never pursued fixing the problem myself. Upon painting one of the bathrooms, I had to move the sink. Upon re-attaching the water lines, I found there to be even less water pressure than before. Upon further research at my local home depot (yes, they actually helped with some helpful advice), I was informed that when I shut off one source of water (ie sink), I need to run a larger source of water (ie bathtub) before opening the smaller line. This process will clear the lines and prevent any debris (corrotion) from clogging the fixture. After doing this simple step and cleaning out all of the fixtures in the house, we now have awesome water pressure! No need for those copper pipes (for now at least).

I have low water pressure after my well house. Well is making good pressure, does not run to long. Water faucet inside well house has good pressure. Filter was plugged badly, replaced and still no water pressure at and outlet after well house. Could water line after well house be full of sediment?
