    Hello, Fitting a back-to-wall toilet in loft conversion, with use of a macerator. Macerator to go behind a partition wall. I have bought a Stuart Turner WC3 and upon unpacking read in the manual that it "must be located immediately behind the WC pan and must not be mounted behind a partition...

    How to choose a mascerator

    Hello, We're in the middle of a loft conversion which includes a small en-suite toilet. It may possibly include a shower, but probably not, due to space constraints. We need a macerator. The outlet will need to go straight up about 1m, up at 45deg (along roof line) about 1m, and along about...

    Create a bed of silicone without it sticking

    Hi, Apologies if this is the wrong forum - I'll repost in a different section if there is a more appropriate option. I am fitting a wall-hung basin to a tiled wall. It rocks very slightly due to either the basin or the wall not being perfectly flat. I am concerned this means that pressure is...

    Non-standard size door

    Hi, I have to replace a bedroom door which is a non-standard size. 715x1920mm, give or take a few mm. Most of the doors in the house are six-panel grain effect moulded ones, this sort of thing, and it would be good to have one which matches...

    Replacing central heating controller

    Hi, I'm renovating a few rooms, one of which contains a very old central heating controller: I'd like to replace this. The wiring looks fairly normal, with one output for "heating on" and another "hot water on". Can I put a new controller on in place of this one? My concern is that this...

    Outdoor step treads

    Hi folks, A have a run of seven wooden steps leading down from a balcony (house is on a hill). Several of the treads have started to deteriorate and need to be replaced. I might do all seven of them while I'm at it. The stringers look fine. The construction is perhaps a bit unusual...

    Tree irrigation

    Hi folks, We have a mature cherry tree in our (fairly small) garden. Long story short, over the years more and more of the ground around the tree has been covered up - one side is a tarmacced alley, one side is under a car port which keeps the ground pretty dry. The last two years the tree...

    Shed door - frame is not square

    Hi folks, We have an old brick shed in the garden which we've recently re-reroofed and refitted. Tomorrow's job is to fit a new door and frame. Currently there is a hole in the bricks, no wooden parts left as they were all rotten. The hole is not plumb at the sides, by about 2cm. (The...

    Is this wiring method OK?

    Hi all, Stumbled across an unusual piece of wiring in my house yesterday. The wiring which feeds the bedroom sockets is a normal ring for the most part - goes from CU to socket to socket to socket ... and back to the CU. However two sockets in one room are fed from a pair or spurs from a...

    Washing machine waste spigot

    Hi all, I need to connect a washing machine to a 42mm waste pipe which protrudes horizontally from a wall in my (new) utility room. It's about 90cm up the wall (as the room is in the cellar and that's how the heights work out) so there's no room for a big tall standpipe. (I've checked and...

    Circulating heat from conservatory

    Hi folks, I am having a cellar conversion done, and it will of course include radiators. However even in the summer (when the central heating is switched off) the cellar is pretty cool. We will have to see whether the insulation being installed will solve this, but I suspect not - the walls...

    Crocuses did not flower

    Hi folks, Last year we planted 30 crocus bulbs under the lawn. This spring, all of them sprouted good strong leaves, and then seven of them flowered simultaneously. The other 23 have still not flowered and I don't think they are going to. Any idea why not? Thanks, Mark
