Plumbing

Using more than one shower at a time.

Anonymous user 28/02/2024 - 3.14 PM

I live in a house with 4 bathrooms, and as long as I've lived here we've had a pressure problem. Whatever you are doing with water, if someone else is using a tap or the washing machine the pressure drops. So if you're having a shower and someone turns on a tap the pressure goes. There doesn't need to be more than two usages of water in the house for this to happen, so it's not as if five people are using it at once. We have a combi boiler on the ground floor and a hot water tank on the 1st floor. Two of the bathrooms are on the 1st floor and two on the 2nd floor. There is no space in the attic above to fit the hot water tank The mains water supply is fine (i think). The pipes are 15mm so I know that this is a problem but will be very expensive and disruptive to sort out. My question is if I replace my showers with electric power showers will we be able to use more than one shower at a time. Thank you.

Are you a tradesperson and able to answer this question?

It seams very confusing. Combi boiler, can provide decent water flow at maximum of two taps. To have a hot water tank with the combination boiler, sound wierd, unless is an electical cylinder, which supply water to a different circuit. The fact that turning on the washing machine reduce the hot water to the shower, look strange, as the WM supply is normally cold. My suggestion is to get a professional plumber, to look at the entire system, from the size of the boiler, to the size of the pipe, inspect cold water supply pressure. It look like a big job to assess and rectify. An insite visit is defenitly requered. Good Luck Tiziano

the problem here is water pressure and volume,no matter what combi boiler makers tell you unless you have outstanding pressure and volume of water they are unable to supply more than one outlet ,unvented cylinder/combi boiler/or electric shower will all suffer from water starvation when more than one outlet is used,you need bigger main with higher pressure,other than that you need a break tank and boosting pump.
