I just spoke to my mate on the phone. The shower and the bath are in separate rooms. The symptoms in both rooms are identical so probably not the thermostatic water temperature controls. A good idea though. I did have this problem on my shower a year or two back when the thermostat got...

I haven't been over their yet. First both myself and my wife caught this cold that's going around. We were OK but my mates health is such that it takes him a while to get over colds etc. Then they both came down with a different bug. He did phone this afternoon (I missed him) so we should be...

Hi Thanks for a novel solution to the problem. There would be room (just about to get two hood units and wiring them so that they are linked wouldn't be a problem but then I would end up with two holes on the wall as well. I would prefer to go with a single fan with lots of power. I have been...

The diverter valve is the component that changes the water going through the heat exchanger from the hot water to the central heating. Basically its a pressure switch operated three way valve. They only apply to combi boilers and the do tend to be a bit temperamental. If you drop the control...

Hi Does anyone have a recommendadtion for a good (by which I mean powerful quiet and reliable) extractor fan. I'm fitting a range cooker and am going to build the cowel. I'm looking for a good quality wall mouned extractor. I'm exhausting directly through the wall to the outside but the cowel...

Hi It's very unlikely that you will have an airlock on the hot water side as the pressure will flush any air out when any of the taps are turned on. I don't really understand what you mean by the control unit. If your system is over pressuring you should see this in the pressure gauge. If...

Hi. I don't thnk think problem is solved. As I said in my prior post this isn't my boiler so the issue tends to slip off the table for me until I see my mate again. Coincidentally I'm going over to his house next Thursday so I'll take a close look then. I wouldn't change the circuit board...

Sorry for the delay in responding. I guess it's time for a confession. This isn't actually my system. It's belongs to a close friend of mine which is why it took a little while to get the information. He tells me it's a " Glow Worm Compact Electronic". No model number though. The way he...

Just to wrap up this post (or at least my part of it). I just fitted the new fan and it works fine so it must have been the circuit board that was the problem. I made sure all the correct sleeving was in place. One again thanks to 'ban all sheds' for the reminder.

I have a Glowworm Combi which is very slow to allow hot water through. Initially when the hot water is turned on there is a good flow of water but it's cold. It doesn't matter how long the tap is left running, the water remains cold. If I turn down the flow and leave it running very slowly...

Yes it was Brown, Grey and Black I checked today when I took the old fan out. Good point about the sleeving I had forgotten to do that and will attend to it when I put the new fan in. Thanks for the reminder. In terms of the switches. It may be that I mis-read the installation I was going...

Hi. I phoned the Airflow Technical services dept to see if they had any ideas and they say this fan should work on a pul cord switch and that the circuit board must be faulty. Airflow give a three year warranty and they have offered to exchange the fan for a new one. I then phoned the...

Hi I've used 4 core wire which is already sleeved. Red for Live Grey for the Trigger and Black for Neutral plus a earth. The neutral and earth are wired to the approprate connections the grey (trigger) is wired to the live switch return as specified in the manufacturers wiring diagram. The...

Hi. Getting back to the original question. If you have a crease in the pipe it will have weakened the pipe wall. Whether it's weak enough to leak is difficult to say but you will have reduced the internal cross section and so restricted the flow rate through the pipe. My advice would be to...

Hi I've just installed one of these and it looks like I've bought the wrong model. The model I have is the 01 version which I now realise won't work with a timer on a pull cord light switch. I have it working a switched basis by wiring both the trigger and the live back to the light switch live...
