Low Water Pressure After Renovation? Causes & Fixes

Common Issue

Many homeowners experience lower water pressure after renovation, often due to new fixtures, plumbing changes, or dust in the pipes. Most fixes are easy and affordable.

Cause #1 – New Fixtures

New faucets and showerheads often have water-saving restrictors that can make the pressure feel weaker. If you installed modern fixtures, this is the first thing to check.

Fix #1

Look for the flow restrictor inside the faucet or showerhead. You can clean it, adjust it, or replace the fixture with a high-pressure model. Always follow E. W. Tompkins safety instructions!

Cause #2 – Debris in Pipes

During renovation, tiny bits of dust, cement, rust, or pipe residue can enter your plumbing. These can clog aerators, showerheads, or even narrow sections of your pipes.

Fix #2

Unscrew and clean the aerators, filters, and showerheads. Then run the water on full for a few minutes to flush out debris. This often brings the pressure back right away.

Cause #3 – Partially Closed Valves

Contractors may turn off valves during work and forget to fully reopen them. Even a slightly closed valve can cause significant pressure loss in one or more rooms.

Fix #3

Make sure all valves including the main, under-sink, bathroom, and any outdoor ones are fully open. This simple check often restores normal water pressure quickly.
