    combi boiler tap

    Take the blue handle off and use a pair of pliers and see if that moves it, just remember to turn it the correct way.

    Waterproofing shower over bath

    For a bath with a shower then normally no need to tank - As long as the bath is in on batons and it has been sealed all the way around and then the bath pushed in, then seal along the top edge and then tile, then seal again. If anything then it may be any internal corners that might get a water...

    Question about mains water pressure/connection

    Ah yep, an Insuduct, not hear it called a chocbox before, though I do see why. Oh my, nope that isn't right at all if that's your mains supply. I hope that 15mm plastic just runs to the outside tap and the mains is fed in somewhere else. Where is your mains stop tap?

    Question about mains water pressure/connection

    Only ever heartd that for electrics?? No - the water mains should not be coming up out of the ground in 15mm speedfit. If you are getting 18-20L/Min at the outside tap then it shouldn't really be losing half that by the time it gets to the bath unless the dynamic pressure is poor? Do you know...

    Insert for black alcathene pipe

    If using a compression fitting on any plastic pipe then it should have an insert. The old black alkathene can go brittle, so even more of a case to use an insert. Always use an insert on MDPE too.

    New custom bath panel and problem floor vinyl gap

    Honestly - try the scotia moulding, it offers a nice looking transition and if it's then coloured the same as the flooring and with the grain showing through then it should match quite well.

    New custom bath panel and problem floor vinyl gap

    Considered a 10mm internal scotia moulding and paint it to match the floor or panel.

    Emptying unvented cylinder

    Yup - if it has an internal dip tube then it should self syphon to the bottom of that. Wouldn't have thought they would have made such a poor quality design faux pas, so it couldn't be drained all the way.

    Emptying unvented cylinder

    That's a strange one, usually the feed and ergo the drain would always be below the lowest serviceable attachment. Only thing you could do is drain it down and if possible disconnect, if not then cut the cold feed and then insert a tube and syphon/wet vac out the water till below the level of...

    Will shower pressure increase after works complete?

    :ROFLMAO: ..... did you tell them that you have an electric shower and upgrading the mains water isn't part of the job, is it just a boiler change nothing else? ..... and what, will you be showering in the toilet? I'll tell you, some companies these days, outrageous.

    triton instaflow 5.4kw single

    Have not but it all comes down to expected performance and what you will want out of the unit. Like any instantaneous heater like this, unless they are high powered (9-10Kw), the performance figures can be quite low at any reasonable flow rate, if you consider an average hand washing temp to be...

    New WC >6m from stack?

    Absolutely and in practice there certainly shouldn't be a problem. It does seem though that the OP did check the regs, hence his 6m max length question, which is relative to his situation with the single WC into a stack and when it's looked at then it really shouldn't have a problem. The...

    New WC >6m from stack?

    Yeah - and when it comes to real world practicalities, as long as the run is self cleaning and doesn't create any issues. It just seems pointless to have 2 contradictory standards side by side though the thinking is there must be a reason otherwise it wouldn't be there - or so you would think...

    New WC >6m from stack?

    Always found that part of the regs contradictory, why that section in the regs - in table 2 - gives max discharge branch length as 15m but in the branch connection diagram it states 6m??

    Hive duel channel

    Good stuff it's working now - BTW - I appreciate that things aren't cheap these days and in a lot of cases more expensive doesn't mean better but with these 3 port mid pos valve heads you usually get what you pay for. There is a reason the Honeywell's are more expensive.

    How do I form a seal between these please

    You need to make a proper seal where the flexi connects over the hard plastic pipe - Best way to do that would be with the bespoke connectors linked to previously or alternatively large jubilee clips. Wrap the end of the plastic pipe in several layers of duct tape to take up a bit of the gap...

    Hive duel channel

    As @ericmark mentions - a Y plan system doesn't send anything to the 3 port valve when there's a HW only demand. The Live comes from the programmer HW on > that runs through the cylinder stat > if that is calling for heat the stat then passes that Live on through to the wiring centre and then...
