    Rainwater got into boiler down the flue

    My earlier measurements were "worst case" estimates. In a eureka moment last night I worked out how to take better measurements (balance the level on two coins to lift it above the obstructions!), and it's closer to horizontal than 1 in 200. If it should be 3 degrees, then it's faulty. In...

    Rainwater got into boiler down the flue

    Thanks for the comments! The insurance company sent round a Gasafe man who made a visual assessment (6 inches of flue is visible, but above and below there are wonky pipes and shelves) which he "confirmed" with a spirit level supplied by me. This included using it to measure the angle of the...

    Rainwater got into boiler down the flue

    Thanks for those replies. I found a short enough spirit level. The flue is *almost* horizontal, but is angled *only just* the wrong way (maybe 1mm drop along the visible 200mm of the flue). Should a service engineer have checked this? I need to pin this on a tight-fisted insurance company!

    Rainwater got into boiler down the flue

    My boiler got flooded at the weekend. Heavy rain and wind blew water into the flue. The PCB has fried (or boiled) itself to death. Is there specific guidance on the angle of a flue that goes approx horizontally from the boiler to the outside? The insurance company are saying they won't...

    Balancing / Lock shield problem

    I have a similar problem. Some of my valves are open only 1/8th turn as otherwise the large kitchen radiator doesn't get hot enough. With that, the pump is juuust strong enough to keep the system hot enough (14-15C drop across the radiators instead of 11-12C that is advised). In my house the...

    Steel bath and other questions...

    A tip from a plumber, but rubbish bathroom fitter that a friend of mine used to work with, was to use lots of Dow Corning 785 as a sealant. He'd fit baths which were wobbly due to his incompetence, but liberal amounts of 785 would then secure them sufficiently. I've used it myself on a bath...

    Radiator only hot at the top

    If the lockshield valves are open and it's still cold, then an alternative possible explanation to sludge is that the radiator is too large for the pipes supplying it.

    Applying matt paint to an interior wall

    When you say you can see roller lines, do you mean lines of extra thick paint. If so, you probably need to do a few more strokes with each load of paint to even them out before reloading. I'm an amateur, and tend to spread on paint quite thin to get an even finish. I probably end up having to...

    Painting a mouldy wall

    Before I could sort it out my tenant treated it with mildew remover and overpainted with bathroom paint - so cross fingers for next winter. Thanks for the suggestions.

    MCB too small for shower

    Thanks all for your help. Sounds like the MCB is "on the edge" and I need to get a qualified person in to check it. That was part of my worry, the original shower is quite old. If the old heat exchanger was 9.5kW based on 240V and the new one is based on 230 volts then the new one is going...

    MCB too small for shower

    Google is a dangerous thing, and I found the following: www.moeller.co.uk/ta_mcb_basics.htm which says:

    Painting a mouldy wall

    My victorian terrace is bigger than the one next to it, so exposes a single brick thick wall to the western weather (ie. it's the width of a brick thick rather than the length) I currently let it out, and it's all been fine for 5 years till last winter's wet weather. I went there last week to...

    MCB too small for shower

    It looks a bit more modern than the one in the picture. I'm guessing it was done in 2001 or a bit earlier. It's got 6 MCBs and an RCD. I knew I should have written down the details...

    MCB too small for shower

    It's black & red T&E with 7 strands of copper per wire - is this enough info, because I can only see the end of the cable (where it comes out of the wall into the shower casing). I assumed it was fine because its the same as the cooker cable... Apparently someone in the house regularly has 40...

    Cable Chasing

    I bought a Challenge xtreme SDS drill with chisels included, from Argos last month for about 40 quid to rewire a house. Cheap rubbish, but it did the job and was cheaper than hiring. The work will be much much quicker, but possibly just as untidy.

    MCB too small for shower

    I'm about to replace the heat exchanger on a friend's shower this weekend, but I noticed there is only a 30 amp MCB on a 9.5kW shower. Apparently it trips occasionally (every few months). The cable is big enough - it's the right size, and the shower switch is rated to 45 amps. So I checked my...

    permitted cable runs..help me if you can

    I'm currently rewiring a house. The electrician who is going to do the Part P inspection repeated the 100 square metre rule, But when I asked him about the cable length rule he looked at me as though I was an idiot. I found my info on www.diydoctor.org.uk/projects/electrical_safety.htm...

    Wire pulling lubricant

    Having been warned elsewhere in this forum about the trickiness of wiring sockets in 25mm back boxes (and having just installed a bunch) can anyone recommend a safe method of lubricating the wires to reduce the force needed to pulled them out of the oval conduit for wiring up, and then pushed...

    Shed socket

    Sorry, getting the jargon a bit wrong. Basically the electrician recommended the same type of CU as the one in my home and the one I saw in B&Q with, I think, 10 MCBs. 5 with the RCD and 5 without. So I was going to copy what I have at home and put the sockets on the RCD ones and the...

    Shed socket

    Thanks for the advice. Appearance is not important as it's in a "utility room" so there'll be cupboards in front of it. I'll consider a separate circuit - I think all CUs come with 5 RCDs these days so that's 1) upstairs ring, 2) downstairs ring, 3) kitchen ring, 4) cooker and 5)...
