Hi all, Sorry if this already appears on the forum, but I am unable to see the posting which I was sure I made @ 16:15 today and have not seen any responses so I guess that I failed to post it correctly.
OK, my first posting herein although I have often turned to this excellent forum for information and help.
My problem: I have just installed a thermostatic mixer bath tap/shower unit for the outlaws which is working “intermittently”. It was a simple job - apart from the usual issues of tight space to get a spanner to the tap retaining nuts. - I had to install the unit since the old folk were having problems getting the fine adjustment required to obtain the correct temperature on the existing non thermostatically controlled unit. Once I turned the cold & hot water stopcocks back on the thermostatic control did not appear to let the hot water through the mixer. To check there was hot water in the system I turned the sink hot tap on. Soon after the mixer tap delivered the hot as required as set on the thermostat. The tap (bath filler) & shower feed subsequently worked fine on Friday. I had a call on Saturday saying that hot water was not being delivered, only cold. Again I turned the sink hot tap on and again the hot water started to flow ok as it did for several further attempts shortly afterward. I made a further check today and again no hot flow. The basin trick did not seem to work this time so I opened the kitchen sink tap & the hot again flows fine.
My thoughts – wrong or right - are that there is either an air lock or water lock that reaffirms itself after a period of time. Or it could be the obscure way the water pipes are configured in the house.
Does anyone have any suggestions on how to resolve this issue?
Thanks.
