Another cause for sporadic water pressure is air trapped in the lines. The air will force the water through the pipes intermittently. There are many ways air can enter the pipes, but one common cause is a bad check valve at the pump.

Why does my shower lose pressure after a few minutes?

Why would my water stop running and then start again?

A common cause is a failed check valve. The check valve or foot valve prevents the well pressure tank from sending water back into the well after it has built up with water pressure. If the valve fails, water streams down the well, and the pressure switch turns the pump on again.

Why is my shower water pressure low?

The most common cause of low shower pressure is a blocked showerhead, as a result of limescale build-up. These blockages obstruct the water flow, leading to reduced pressure over time. Most showers are fitted with a filter, protecting the pipework from debris, but this can become partially blocked by scale.
