New Shower - Hardly any water coming out of it. Help.

[nicky1001]

Hi, My very first post. I will try my best to give as much info.

6 months ago I had a new boiler installed, Vallient 831 combi boiler. It works a treat. Last week I had my bathroom refitted, I used to have a shower tap on the old bath, worked great loads of pressure. Anyway, had a thermostatic mixer grohe 3000 installed, looks great...got in it this morning (first time) and what a disappointment, water literally trickled out of it. All the valves are fully open, not sure what the problem is...Any ideas would be much appreciated.

Many thanks,
Nicola

Was the grohe not commissioned prior to the fitter/ plumber leaving the property?

Yea, did you not see it working before the fitter left? It's either some valves on the feeding pipework that aren't fully open, some grit clogged in the wire mesh filters or the cartridge has gone strait away (happened a few times with new showers Iv fitted).

Also check the simple basic things. Does the shower head have a multi spray function. It may be jammed between settings. Shower hose kinked/ blocked.

Hi, thanks for the replies. I didn't see it working no, the shower valve was only put in day before yesterday & the bathroom floor tiled so couldn't walk across the floor to turn on the shower. The guy who has been doing the install has to come back to finish off some bits, I haven't been able to get hold of him to tell him off the problem yet.

The shower head has three different settings, there is hardly any pressure on any of them, no kinks in the hose, in fact the shower pipe resembles a silver hose pipe, quite sturdy so would be difficult to "kink" I will try and unscrew it this evening and check to make sure there is nothing stuck. Thankfully the side of the bath hasn't been tiled yet so there is still access.

I'm hoping that it's something that can be sorted out relatively easily (fingers crossed) rather than having to rip the bathroom to bits again. :-(

Then you need to get hold of the fitter. I take it the hot and cold on the basin / bath is working ok? Try removing the head completely and see it its flowing well from just the hose.
