    Leaking ballofix 15mm isolation valves query

    Had to repair toilet cistern water feed due to bodged pipe perforation "fix" (by plumber when the bathroom was installed many years ago) giving up the ghost. As it entailed replacing a section of pipe I thought it worthwhile putting in a 15mm ballofix isolation valve at the same time. I had...

    Building Regs / FENSA required or not for THESE french doors?

    Considering having French doors and side panels replaced (each side panel is, as near as dammit, same size as one of the French doors). Plan is to have these made of wood with argon filled toughened DG and to leave the existing overall frame in place. So the existing main frame and the vertical...

    Lighting circuit connected to two MCBs

    I went to change a light fitting in my mother-in-law's house. Tried turning off each of the 6 amp MCBs in turn to isolate the fitting in question. No joy - the light always worked. A few combinations later, I found that turning off two adjacent MCBs had the desired effect. Any good reason why...

    Straight consumer unit switch or not?

    House completely rewired c.1990 (under auspices of IEE 15th). However, consumer unit was not replaced and still old re-wireable fuses (which are very reliable and have never been an issue). If want to have new consumer unit installed now, would it be just a straight switch-over job between...

    Time to replace CH pimp or not?

    I know the answer might be "how long is a piece of string", but my existing CH pump (Grundfos Selectric Mk II UPS 14-50x18) is now 28 years old. Is it time to replace to be on the safe side? Or go for IIABDFI (if it ain't broke don't fix it)? Also, would the currently available UPS2...

    Low patches in painted render due to old paint lifting away.

    I'm looking at repainting my exterior rendered walls (again). The house is about 90 years old and, unsurprisingly, been painted many many times in the past (including by myself over the 32 years I've lived there). The render itself is sound. Each time I paint it a few new hairline cracks...

    Electricity for gas cooker - wall or trailing socket?

    I’m looking at replacing a freestanding gas cooker with another one. The existing one has battery operated ignition and is not connected to mains electric. The replacement would almost certainly have mains powered ignition. There isn’t a wall socket that nearby and installing one would mean...

    Remeha Avanta 18v Ionisation Current

    The manual for this boiler states that the ionisation current should be between 3μA and 9μA. On my newly installed boiler, upon ignition the current runs up over a short period to typically reach around 9.6μA to 9.7μA. Is this apparently slight variance anything to be...

    Replacement of Potterton Netaheat 10/16

    I'm looking to get a straight replacement of a gas Netaheat 10/16 (10 - 16kw believe it or not) on an open vented system which has a single pumped circuit covering rads (TRVs all round) and HW cyl. Any recommendations for quality boilers to suit would be much appreciated.

    Motorised Valve Actuator for Sunvic eml3454

    I'm looking for an actuator that fits a Sunvic eml3454 2-way valve body (so, presumably, bolt-on rather than clip-on) that supports the following connections: - Neutral - Switched Live Input, to open valve. - Live Output, switched on by the actuator when valve is open. - Permanent Live...

    Replacing Drayton Cyltrol

    The Cyltrol (1 inch Angle type) on my hot water cylinder is starting to seep when adjusted and so I intend to replace it with a new one. I'd be grateful for some advice on the following points. 1. Is it necessary (or even advisable) to drain the cylinder (obviously the CH would need to be...
