    Greywater waste pipe into new rainwater hopper downpipe

    That’s a mare, don’t see how that’s allowed, how is anyone supposed to complain or stop anything before it happens. That’s means the LABC wash their hands of it? That leaves the whole process open to serious abuse, happens all too often these days. Surely that’s all supposed to happen at the...

    Connecting toilet that has a 15mm connection, not 1/2inch

    We were always taught it was to do with Internal Diameter (ID) and Outside Diameter (OD). Imperial was always measured in ID sizes so with the pipe wall thickness 1/2” ends up slightly larger than 15mm but will fit 15mm compression. When it comes to 3/4” pipe though it only reaches a bit over...

    Gutted over creaking shower tray. Adjusting riser legs under shower tray possible ?

    Bottom part of the foot, on the floor, twists clockwise, to draw it out of the leg. Unfortunately it can be the bain of these riser kits, terrible things IMO.

    shower pl8 before or after tileboard?

    A shower fixing plate can be secured to any wall surface, be it brick, board, stud work etc. The depth is defined by the length of the tails through the plate and then the wall covering, which can really be any length, so in effect it can be as deep as you want. Not too deep though as you still...

    Expansion vessel help please

    Didn’t see anywhere in the post where it says the EV is in a completely different place, hence why I said Even then, given the additional difficulties of pressure drops and the boiler shutting down prematurely, it still may be easier to get a professional in.

    How to attach 35mm brass bottle trap to solvent weld 40mm waste pipe

    I’m on holiday and beer at the pool can be a bad thing when it comes to IPads, the sun and trying to read the screen properly :LOL:

    Expansion vessel help please

    Yup, I hate auto correct sometimes, it was mean to be “shouldn’t”

    Expansion vessel help please

    As was suggested in your previous post, I would recommend you get someone in to sort your system out, what you are attempting isn’t the easiest to DIY, it needs knowledge for that type of boiler, as it seems you are finding out. Also, If the expansion vessel is down the right hand side of the...

    How to attach 35mm brass bottle trap to solvent weld 40mm waste pipe

    Yeah, spotted that 2nd of looking, (y) I should know better that to assume anything on here without checking.

    How to attach 35mm brass bottle trap to solvent weld 40mm waste pipe

    Presumed it was a 32mm waste given it was a basin trap, ah well

    Bath mixer tap - 22mm or 15mm

    If you have a cold water cistern (CWSC) in the attic and HW cylinder on 1st floor then you really need full flow 3/4” taps to maintain proper flow. Anything less and it will reduce the flow.

    Is my boiler ignoring the controls?

    Depending on how it is wired, if it’s a standard S plan 240v switching, then The boiler will show the rad symbol regardless of whether its heating the cylinder or the rads, as that is just showing there’s a call for heat at the boiler to create hot water for the whole system. Where that hot...

    Greywater waste pipe into new rainwater hopper downpipe

    No, waste water that has been diverted to a collection system would be say a water barrel or storage tank and that water can then be recycled say to fill toilets etc. Water that ultimately heads down the drain, however it gets there, should be covered by Doc H. As I mentioned, I’m not sure...

    boiler service - flue check

    I think what the trouble here is what’s defined as a service and what they consider acceptable, you may need to discuss that with them. With a 42CDI a fan pull (pressure) test would usually need to be done. Results would dictate if the HEX needs opened up and cleaned or not. That’s even before...

    Random gurgling on one of the radiators

    Not normally, air in a system tends to head to one rad, usually the highest one on the system. Hence why it’s usually the upstairs towel rad that catches it all.

    Is this tap repairable

    @Fallout is a tradesman, so all he needs to do is add a seat cutting tool to his tool bag. That being said, in all my years of doing this I’ve only ever had to cut the seats on a deck mixer twice and then that was just because they were pitted not that they actually really needed it. I’ve found...

    Random gurgling on one of the radiators

    Could be air settling out but unless there is a leak then that should stop after a short time. Another area could be noisy valves but that would only be obvious if you’re running the system. Do you have a hot water cylinder.

    Is this tap repairable

    I’m very much a believer is repairing rather than replacing if possible. Too much thrown away these days for the want of a little work and some new parts.

    Drain, refill and parts

    You need to understand what your system needs first. No point in just buying things and throwing them on. As suggested, if the pressure rises when the system is on, the red vessel (EV) needs checked and either serviced or replaced. The 3 port may be at fault but wiring, programmer etc needs...
