I remember back in the day when I used to work on aircraft they had devices called 'hydraulic fuses'. If there was a hydraulic leak anywhere downstream then the flow rate went up and the fuse closed shutting off the oil. They were simple mechanical devices with no electrical parts. I just wonder...

Thanks for that John. I will order one of these for my next service.

Hello chaps I have always serviced my own Potterton oil boiler and in recent times seem to have increasing problems with the Riello flex hoses that connect the oil supply to the pump. They just don't seem to last any time at all these days and quickly start leaking where the end fittings are...

I am not playing around and I am trying to get it sorted. That's why I am asking questions. I would gently suggest that is how human beings progress. When we don't know the answer to a problem then we ask people who are more knowledgeable than ourselves.

I know all the water pipes in the house were bonded together in the attic when a shower was fitted. Would that mitigate the risk?

Would that enable me to determine if the earth route through the spike in the ground is is performing to specification? Regard Stuarts

Thanks for your very clear explanation John. I guess to test that is going to be way beyond the capability of my ten quid multimeter.

Thanks for the reply My understanding is that a fault current will always take the best route to earth that is available. So, if you had a situation where a fault current is earthing by an alternative route, like a rising water main, then does it follow that the designed earth route would be...

Thanks for the reply. I've unplugged everything that can be unplugged and still seeing around 100mA when clamping at the meter tails but haven't had a chance to delve deeper at this time. Just wondering if moving the main earth from the spike in the ground to the water pipe, as a temporary...

Hello chaps. Me again with a further question if I may To recap I have a TT system with an earth leakage that I haven’t had a chance to track down. The TT system is connected to an old Wylex fused board with a Crabtree VOELCB connected to an earth spike. I briefly borrowed an earth leakage...

Well I signed up to an EON tariff that required for me to accept a smart meter. They kept asking for permission for their guys to fit the smart meter and I just kept ignoring them. Eventually the two year contract expired and I reverted to the standard variable tariff and they never did fit a...

Hello chaps Just a quick question about an oil boiler replacement. I have an existing elderly Potterton oil fired boiler in the kitchen and basically in the middle of the house. It has a single wall flex stainless steel flue pipe that runs up inside a brick chimney. I want to replace the boiler...

Obviously you cannot do much in someone else's house but if that radiators a single panel, as it looks to me, then you could swap it for a double.

Not good but I would just fit lengths of 1/4 round beading to cover the gaps. Just tack it to the skirting board.

Did it have a steel crittall window.
