How do you increase the water pressure for showers?

We live in a house that is over 30 years old. The water pressure for the shower is terrible. It is even worse if two people try to take a shower at the same time. We practically have to stand under the shower head. What can I do to get better water pressure?

    Is it only the showers or is there low flow in the sinks too? Do you know how much water pressure there is entering the house? City water or well? Plastic, copper, or steel pipes? Have you always had this issue or has something changed?

    There could be a number of reasons why your water pressure is low, none of which can be determined remotely. It is a good investment to purchase the time of a professional plumber to evaluate the entire system and make recommendations. If you have plumbing skills and tools you don't have to pay him to follow through on the recommendations, you can do it yourself.

      The flow is pretty low everywhere. We city water. there is a combination of copper, steel and pvc pipes. I think it was copper originally and the owners upgraded as they made repairs. Thanks for your input.

    Start by getting a shower head, that has several water options. You can purchase this in a department store. If you use the pulse, which has 3 water sprays, this might help the pressure in the shower. This shower spray has 6-7 choices. If you can't get the right pressure, Google (how to increase water pressure).

    It sounds like your water pressure regulator has failed. In our area when it fails we get crazy high pressure but your area may be the opposite

      It will be a brass component with an adjusting screw on your main waterline coming into the house. First, though, check to make sure all incoming line water valves, including outside, are fully open. Sometimes the main line is simply choked down and not turned on all the way. You can also use a handheld pressure tester on an outside spigot to find out what your pressure is coming in from the municipality. There is also a possibility that some of the older pipes have become clogged with sediment.

    First, take off your existing shower heads and check for a water regulator, looks like a plastic plug in the pipe to the wall. If it’s there, remove and put showerhead back on. Worked for me!

    Go to your local home improvement store and buy a cheap shower head (the one I picked up cost $1.50). If you look down inside of the showerhead you'll see a washer which constricts the water flow. If you take a drill and enlarge the hole, thereby increasing flow, thewater pressure will increase

    Steel pipes are the culprit. Inside of the steel rusts and seems to grab every bit of calcium that tries to flow through. I like copper, but CPVC is my material of choice. It is cheap, readily available, requires relatively few tools, does not clog like steel, and does not corrode away like copper does with acidic water. It does need more supports to hold it up along the floor joists than copper or steel.

    Replace the steel with CPVC and I will give you a better than 80% chance that the low flow issue will go away.
