Why does my water pressure drop in my shower when someone flushes the toilet?

Your shower and toilet may share the same water source. i.e. your mains supply or water tank in the loft. The flow of water from this source will be divided between the number of open water outlets. If you’re in the shower and your toilet cistern starts to refill, because somebody has just flushed it, pressure to the shower will drop.

If this happens because you have a low water pressure the same is probably the case for any outlet is open. So the same shower will experience a drop in pressure when someone brushes their teeth or a dishwasher is on.

The solution is to improve the water pressure.

A Proflo water pressure booster is designed to remedy these types of situation by increasing both flow and water pressure. This will allowing you to have multiple outlets open at once without affecting flow.
