    CBB65 start capacitor?

    You would think that ST would use similar capacitors in their later pumps, aint broke don't fix it type idea. I believe more modern 10uF capacitors ahould work without issue though surely? as long as it's the same μF rating then the motor shouldn't know the difference? Not an electronics chap...

    Remove connection to downpipe

    If the cast iron is now redundant then cut it flat and then chisel it back so it is recessed, then fill it with insulation or some other filling material, or even a brick and then seal it right up with morter. Ideally it would be chopped and then the whole pipe chiselled right out and then the...

    Sealants/adhesives/Hybrids -Fitting anyone using 'hybrids' to secure/seal to walll?

    So you will be sealing the edge of the bath to the final wall covering and that covering is cladding? I'm not sure what's meant by cladding here, cladding is usually exterior and made up of vertical T&G panels and the widest of them are usually around 250>300mm, you do get interior panel of...

    Broken bath plug and supplier has changed dimensions- anyone know a plug that will fit or any other solutions? Phoenix WA003 thanks so much

    Has the click clack plug snapped off? If it has you may find that the click clack mechanism might screw out of the waste, if so then you may be able to replace it with one the same same thread size. That being said it doesn't look the correct shape at the top to be removable.

    Kitchen Pipe Falling Off

    Cant - It's push fit. Not enough pipe coming out from the wall, can the pipe from inside be pushed out more and then clip the pipe internally and externally to stop it from moving. That being said it's not the right pipe for outside work, it's push fit and as such is PP plastic that isn't UV...

    Poor hot water system.

    Dependent on how the water is actually supplied, i.e the farm is on a single main and then the houses are branched off that supply, then the farm will be metered anyway as non domestic. The usage will be calculated on the farms mains meter as they will probably be charged as non domestic, with...

    New bath waste not sealing

    The water tight seal isn't normally created on that side of the waste - it's usually created on the underside of the waste by the thick washer in between the nut and the bottom of the bath. If there is a weep underneath then ensuring the base of the bath at the waste hole is nice and clean and...

    Poor hot water system.

    If the mains is 1.8bar with one outlet open but the flow rate is 4L/Min then there must be a restriction in the supply somewhere. If the dynamic pressure is 1.8bar then the supply should be delivering much more than 4L/Min, unless the supply is on an excessively long run of 15mm pipe. If the...

    Wodar 4 in 1 tap - pressure problem regarding mains water

    Unless your dynamic mains pressure is really good then their flow can suffer with the small waterways they use inside, what is basically, a standard sized tap body.

    Extractor fan installation

    Whilst an extractor may help - the best thing you can do, once the shower is finished, is open the door a bit and keep the window open until the room clears and cools down, natural ventilation is the best approach. Have the window open whilst showering to allow the steam a path to escape. Also...

    42 vs 40mm waste pipe

    ABS solvent weld plastic has an OD of 43mm - usually compatible with PVC as both can be glued though PVC does come in imperial and metric sizes - PP push fit plastic has an OD of 40mm. ABS and PP - for some reason - are both called 40mm or 11/2" PVC waste pipe sizes are rarely used in domestic...

    Radiator replacement - should we go for higher BTU than needed?

    More than enough - the radiator works by it heating the air it draws in from below and circulating that out the top and out into the room, it won't lose a lot of it's efficiency being close to the sofa No but I bet it got there quickly .... used to have a TVR Chimaera ;)

    Radiator replacement - should we go for higher BTU than needed?

    If you can only fit one rad then I'd use a conventional, albeit contemporary design, if you want it to look good. A Type22(K2) radiator behind the couch is proven to work well, as long as there is a reasonable air supply allowed to get to the bottom of the rad and a little space left between the...

    Hanging a rad on a plasterboard and osb wall

    If that's 9mm OSB onto proper batons then it should be ok. Try and pick up the batons for at least the top brackets and use nice large fixings, or if it's easily opened then run an extra baton in for the top brackets

    Radiator replacement - should we go for higher BTU than needed?

    Honestly - I've had clients ask me to pull designer, tubular, vertical rads out out more times than I care to remember because they just fail to heat a decent sized room properly. I removed 3 - 550mm x1800mm doubles from my own living room (26m2) because they were woefully inadequate at heating...

    Radiator replacement - should we go for higher BTU than needed?

    Heat loss calcs are designed to provide the amount of heat that a given room can lose in an hour in Kw, that is then matched to the output of the radiators at a given delta that can then replace that heat loss, that is then designed to ensure that the space is comfortable to be in. Unfortunately...

    Radiator replacement - should we go for higher BTU than needed?

    When you say horizontal, how do you mean? Just a normal convecting radiator or a designer type? You do get flat panel, contemporary looking rads that are convectors BTW.

    Underfloor pipe installation

    What is the void being filled with, on top of the KS, to create the thermal mass? Is it to be a biscuit mix? I'd also be looking to insulate the loops under the joists. I guess if to be picky then the loops could have gone through the joists and the insulation extended.
