Low pressure in new bathroom

Josephine85

I've just had a new bathroom fitted and previously the water pressure was fine but now the shower pressure is so low it's barely usable. The new shower has a large and a small head but even if use the small head the pressure is massively lower than before. We have a combi boiler

What type of shower is this ? Electric as in it lights up, has switches ?
I would think so on a combi boiler.

If it is electric, find the priming sequence on Google and try re priming the shower through the test cycle, I have seen some fitted by bathroom men who had no idea the shower needs to be commissioned to work correctly, if this has not been done, it will run at lowest pressure on the reducer.

No, it's a mixer shower, same as the previous

I have no idea what you are talking about

So what has been changed - new mixer, new pipework?

Either the shower has flow restrictors fitted or the pipe work hasn't been flushed & the filters are blocked, I'd get your fitter back

really?

its quite simple, the poster thought that the op might have had an electric shower which hadn't been commisioned properly after installation (which needs to be done by pressing a specific set of buttons for the shower to run by itself for a minute or two and set itself up according to the incoming water pressure etc)
It happens,the installer doesn't read the manual and the shower is left in factory mode with very little flow

Shower has moved to a different wall so new pipework and a new shower, spoke to installer but be said there aren't flow restrictors and he thought maybe it's because the new shower has 2 outlets

Showers are often specified for high and/or low pressure systems. Perhaps your chosen shower does not match the water pressure?

We had a similar problem with our new shower (although it only had one head), and so we changed the shower head to the following which made it useable:

An electric shower runs off of the cold water main & doesn't require any buttons to be pressed or setting up, you are talking about a shower which may or may not have a pump & this is fed from a roof tank & as the poster assumed the op had a combi boiler then they wouldn't have a roof tank, so like I said I have no idea what you are talking about
