Thanks for the offer, but I think this might be less disruptive.

Hello, I need to fit a strap on boss onto an internal 108mm copper (yes, really) soil stack. What is the best tool/technique for cutting out a 57mm hole? I wouldn't be asking if it were made of plastic.. Many thanks,

Thanks, Dave.

Hello, Definitely not PRV operating. Maybe isolating valves hidden by plastic undertray. Thanks.

Hello all, I had to turn off the incoming cold main the other day and drain down the cold/hot pipes to and from the loft installed combi boiler to replace a leaking gate valve. Slightly puzzled that the boiler seemed to be dumping its stored hot water into the cold supply that feeds the...

Meter is a Schlumberger and it says R5 on it. Also says 212 ft3 per hour. Thanks for your help.

Pipe splits at (internal) meter just after bendy metal hose from regulator. 28mm copper goes off to boiler in loft, and 1 inch barrel pipe goes off towards kitchen. Somewhere en route, this reduces to three quarter inch barrel pipe. Seem to have enough pressure for existing four burner gas...

Hello, this is a domestic set up. Incoming gas main is one and a quarter inch barrel pipe, and the 28mm copper take off to the boiler is as soon as possible after the meter. Thanks

Hello, I've just had a 39kW Vaillant combi installed and a very good job it does too. I want to install a range cooker in my kitchen, but am not sure if I will have enough gas pressure when the boiler is doing its thing. The boiler supply is run in 28mm copper direct from the meter. The...

It's definitely a 15amp requirement as it's rated at 3.4kW. (It's a french cooker).

Hello, is there any way that I can wire in a dual fuel cooker requiring a 15amp supply to an existing kitchen ring circuit, or do I need to run a dedicated supply back to the CU? The existing ring supplies a dishwasher, fridge freezer, toaster and kettle. I am aware of Part P. Many thanks,

Thanks for your replies. Air in dead leg now unlikely so will try higher threshold on d88. Thanks again.

Hello, Just had a Vaillant 937 storage combi and rads installed, all done very nicely. However, when I turn off a mains fed cold tap, the boiler starts up, at least I can hear the fan coming on. I thought this might be related to a dead leg with air in it somewhere in the cold water...

Thanks for speedy reply.

Sorry to bring this one up again, but can anyone clarify whether it is still the case that in respect of non-notifiable minor works, a Minor Electrical Works Certificate can be made out by "a competent person who need not necessarily be a person registered with an electrical self-certification...

Yes, well, I'm working on that industrial chic look. The cable tray is to be boxed in and doesn't enter a special location and was a cleaner solution than hacking off the plaster. As far as connecting to an existing ring is concerned, is there a requirement to check what exists already...

Hello, I want to take a spur off one leg of a domestic ring circuit where it runs up the wall in a cable tray. Am I right in thinking the best way to do this is to remove the cable sheath lengthwise without cutting the cable and bare the conductors before placing the (unbroken) conductors...

Sorted, thanks for reply.

I had been trying in daylight, but now it's getting dark.

Hello, I've got a PIR controlled wall mounted security light that I can't seem to get onto the security setting after turning the main power off. Got no instruction manual, but seem to remember you activate these by turning them on and off in a sequence at the switch. Any tips? Thanks
