Why is my water pressure low in the loft shower?

This is a very common problem, and it’s usually a result of the fact that the loft shower is higher up. The additional height that water needs to travel mean that water pressure is lost.
This can be the case no matter what type of hot water system that you use, but it’s a particular issue for gravity fed systems where the shower head is not much higher than your header tank.

To put this in perspective, your water pressure can decrease by up to 0.5 bar for every floor that it has to rise.

There are a number of solutions to this problem, but the most effective is a Proflo water pressure booster. This will increase both the flow and pressure of the water vastly improving your shower as well as the pressure elsewhere in the property.
