Each possible reason for low pressure requires its own steps to resolve the issue.


To check for debris in the pipes, remove the shower head and turn on the shower faucet. The water should come out in a strong flow. If it does, it is worthwhile checking the shower head, as that can become clogged with debris, too.

Pressure regulators can become faulty. They control the water pressure that gets into the house, and if faulty should be repaired by a plumber.

Water leak

Water leaks can also be the cause of a low pressure shower. Most fixes will have to be carried out by a plumber, but it is possible to check for leaks.

If the reading has changed, then the water is still flowing, so there may be a leak.
