Why has the pressure in my shower dropped?

One of the simplest reasons for the lose of shower pressure is a blocked shower head. Shower heads accumulate mineral residue when the shower head is in use. Once the water has been shut off, over time these mineral deposits will bond together and create a limescale build up inside your pipes or shower head.

Why does my shower make a thump noise?





The banging noise you hear in your pipes when you turn off the shower or other faucet is a phenomenon known as water hammer.

You could have one of two problems if your faucet makes a clunking noise and it continues while the water runs. The first could be that your water meter isn’t large enough. The other is that the water pressure is too high and you may need a pressure-reducing valve installed at your main water supply.

What causes water pressure to fluctuate?

Air Trapped in Pipes





When air gets trapped in pipes, it can cause fluctuating, and spluttering water pressure as the air and water move through the pipes. Air trapped in pipes acts as a valve, causing water flow to stop and start in fits and bursts.

When the washers inside a shower valve wear out, they can become thin enough to vibrate as water flows past them, and the vibration creates the high-pitched sound you hear. The solution is to turn off the water to the bathroom, disassemble the faucet and replace the worn rubber parts on the cartridge or valve stem.

Why do I suddenly have water hammer?



Water hammer is usually caused in high pressure (e.g. mains pressure) water systems either when a tap is turned off quickly, or by fast-acting solenoid valves, which suddenly stop the water moving through the pipes and sets up a shock wave through the water, causing the pipes to vibrate and ‘shudder’.

What causes water hammer in shower?

If you live in an older home, the hot and cold-water supply lines can become loose and bang against the straps that secure them in place. When this happens, the water pressure causes the pipes to move and tap against the wall or brackets. This can produce a knocking sound.

Why is my bathroom sink making a knocking noise?

A: The knocking sounds are what’s known as water hammer, caused when water flowing in pipes suddenly shuts off and vibrates with enough force to cause the pipes to knock against wood framing.
