    Motorised valve seems way too hot

    With the head off the 3-port valve you should be able to move the spindle between its positions using just two fingers. It should move very easily. If it sticks then moves, feels kinda gritty or you cannot move it by finger power alone, the body of the valve is shot and the resistance is causing...

    Tap Conversion needed

    Can you show us a picture of the tap or fitting you wish to replace, in situe, or where you intend to fit one? I'll be honest and say that I don't really understand your question so if we could see a picture of where you want to put the tap I might understand a little better. Thanks.

    Toilet troubles - not flushing

    If the pneumatic hose is just pushed onto the back of the button, simply pushed onto a little spigot, you can at least eliminate the bellows inside the button from being at fault by pulling the hose off and blowing sharply down it. I don't mean just blow on it like you are doing a dandelion...

    Help with thermostatic radiator valves

    What Gasmk1 is saying is there are TRVs you can install which have the capability to activate the boiler. Standard TRVs are purely mechanical devices that close off the supply to a radiator when that room gets to temperature. They do not communicate with the heat source. To have the...

    Underground Oil Line

    I expected they would.

    Dripping Tap. Need help.

    See @moonlight's advice above. The complication here is that the cartridges you have use something called a "carrier spline" which is the white plastic part attached to the brass spindle. They can sometimes be bought separately which means you might find the correct cartridge but not recognise...

    Underground Oil Line

    No, but tanks have to comply with strict regulations regarding distances from boundaries and openings and vegetation, the distance the hard base must extend beyond the footprint of the tank, proximity to eaves spaces. These are all to do with fire prevention. I was just asking if the pipe you...

    Underground Oil Line

    Is it fire resistant though?

    Aqualisa / megaflo drama

    This sounds like an unbalanced hot/cold supply issue at the shower valve. It would really help if you can upload a picture of the combination valve on the cylinder including the pipework below it that feeds into the cylinder. We need to ascertain if you have balanced supplies or not. If your...

    Underground Oil Line

    If you do use plastic, nothing wrong with that especially if it's a particularly long run but you should not have plastic oil lines above ground. You need to change to copper before coming up above the surface which means access chambers where you make the transition as no joints should be...

    What can happen when the wrong pump is installed

    Unfortunately this happened circa 2009 if I remember correctly. I wonder how they've got on in the subsequent years? They were understandably worried about anything else leaking after all the damage was repaired. They had leak sensors installed all over the place and asked me to bring the mains...

    What can happen when the wrong pump is installed

    I see you guys are correct. I was a 2nd year apprentice at that time and that's what I was told back then, wrong pump. However I looked up the model just now an it is a bronze pump indeed. I now think Last has the right idea. Either way it is quite incredible just how corroded it became before...

    Toilet troubles - not flushing

    Until we know what setup you have, the simplest manual flush you'll get is half a bucket of water chucked into the pan to clear it until we can help you get it fixed.

    What can happen when the wrong pump is installed

    On a secondary return the water is frequently replenished bringing new oxygen into the system. The pump oxidises (rusts) and looses its integrity. Then the front fell off!

    What can happen when the wrong pump is installed

    I've just found a load of old photos I took when I was an apprentice. Among them was this standard circulating pump that was installed on an unvented secondary return circuit. It should have been a bronze pump as I'm sure you know. I was called to re-install the unvented cylinder which was up in...

    Leaking Overflow from Baxi DuoTec Combi 28 HE A. is it faulty PRV ?

    Thanks for taking the time to update. That's always appreciated and can help future forum users or at least give them some idea what to expect in similar situations.

    Fitting an Airvalve / bleeding point in central heating

    Both those bits of pipework in your picture most definitely are about as good as an air-trap can be. If the redundant sections of pipe cannot be cut right back to where they tee off then yes, air bleed vents will do the job. The one on the right looks like 22mm and the loop on the left looks...

    Leaking oil tank from compression fitting

    The pipe needs to be held firm into the full depth of the fitting whilst tightening otherwise it will likely just slip off as the nut is tightened in. Either that or it simply never was done up tight enough in the first place. It also might be the wrong olive used. Some are longer than others...

    Lowering return temperatures

    If you can reduce the pump speed and therefore water velocity that will lower the return temperature. The problem there is if the pump speed is too low for the system you have it may not heat the house adequately. It's all a real balancing act!
