Please help - shower problem...

Cold water tank "infill valve" replaced - now shower doesn't work...

Hi, I'm new here and pretty dim, so please forgive any stupid questions.....

Our cold water tank in the loft has been overflowing and tinkering with the ball valve (I think this is the correct term?) wasn't working so we called a plumber.....

He came yesterday, looked in the loft, went to get a part from his van, turned off the main stop cock and "replaced the infill valve" because it had become "gunged up"...... He turned on the water when he had finished and bade us a cheery goodbye.

Later, when I went to use our (fairly basic electric) shower (which draws cold water only (from the mains, I think) and heats it as it uses it) I got the low pressure warning/cut out and there didn't seem to be any water coming through at all...... could this be related to the infill valve replacement or is it just coincidence?

We tried turning it on about three or four times with the temperature set at its coldest (on the 'high' pressure setting and the 'low' pressure setting) but we're afraid of damaging something if we run it for too long with no pressure...


We also checked that the mains had been fully opened - it had.

Then I dug the manual out from my files...... it describes a 'commissioning procedure' to be performed post installation which requires the pressure to be set at MINIMUM..... so I have tried this, but it has made no difference.

There is a warning in the manual that says: "After any servicing of mains water supply, always ensure the unit is started on COLD to purge any air in the pipework."

The shower has something called a Pressure Relief Device; the manual says that if this is activated, we need to "...contact Customer Service for advice on replacing the PRD."

Is it likely that the PRD has activated? The manual says: "...if the PRD operates, then water will eject from the bottom of the unit" but we don't think water HAS 'ejected from the bottom of the unit'.

As things stand, we can't get more than a dribble to come out of the shower, with the 'low pressure' light coming on.

Can anybody please help me to get the shower going or do I need to call the plumber back? Or do I need to get a new shower?

Should be SO grateful for any advice......

Try taking the spray head off the hose and let the hose dangle into the tray or bath open the shower in the cold setting and see if that clears the fault best of luck regardsTurnpin:wink:
Thanks Turnpin.... yes, the head has been off since we started and we've tried starting from cold and from hot, as per the 'commissioning' instructions in the manual....... sadly, still just a dribble! :thinking:
 
Bizzybee, what make is the shower? if its a Mira, (newish one) remove the case and near the cold feed inlet you will see there is a blue coloured button. Depress this button until water comes out of shower head. Your shower is now bled. Replace cover and use!
