First post so bear with me!
Have a 'Trevi' type (venturi) shower installed which has worked well for over 4 years. Just recently the water temperature has reduced, even though the hot water basin tap temperature is ok.
Turned off the water mains to investigate and found no problems. I was expecting some restriction in the mixer unit, but found nothing. Now I have re assembled and reinstated the hot and cold water supplies.
However, I now do not get any hot water at all through either the hot water basin tap or the shower - cold water is ok. All other hot water taps are working fine. Just this one in an en suite bathroom.
1. Any ideas what the original problem may have been?
2. How do I get hot water flowing again to the taps and shower.
Thanks in anticipation
