    Removing Chatsworth 1928 thermostatic mixer shower cartridge

    Fixed! I'm posting a summary here in case anyone else happens to come along with a similar issue. First, the schematic for this shower valve confirmed for me that the tile backer board was concealing a grub screw (see "shower valve" image below). I used a dremel with a diamond cutting disc to...

    Removing Chatsworth 1928 thermostatic mixer shower cartridge

    Shower seems to have a stuck thermostatic valve alas. I've got the plate and handles off this shower valve, and removed the lock pin (I've put it back in place for the photo), but can't seem to budge the cartridge back out (it does push back into the wall about 1cm, somewhat alarmingly). Is...

    Venting room-in-room wall

    In order to address damp walls (partially underground) in our kitchen at the back of the house, I've built a wall-in-wall using a steel track & stud system. This has done wonders for dampness in the room, however I'm now to the stage of closing up the various openings, particularly re-instating...

    I've got a loft full of sawdust

    I've begun prepping our loft for boarding up, and have discovered much to my surprise a huge amount of sawdust underneath the insulation inbetween the joists. The attic is a large space, around 90m2, and is apparently full of the stuff. This seems problematic on a number of levels, so I'd like...

    What pre-cast cement blocks would you recommend for retaining walls?

    Yeah, I had noticed that each block technology does seem to have a particular sort of engineering that went with it - thus my search for testimonials. Just out of curiousity, when you say traditional masonry, do you mean a brick mass wall, e.g. double flights at the bottom working up to single...

    What pre-cast cement blocks would you recommend for retaining walls?

    I'll be excavating some soil from a hillside in front of our house in order to add a driveway in front, so will be installing a retaining wall to hold up the soil. After surveying various options, I'm leaning towards using pre-cast concrete blocks for the build, either in a cantilever style or...

    112, 125 or 150mm?

    It seems that the last aging length of rainwater guttering has now begun to come off the roof of our recently purchased (but very old) home. So now I've got to replace it before monsoon season properly hits us here in Wales. I'm very much hoping to keep fascia and brackets in place and simply...

    Is it possible to use two rads off one TRV?

    Also curious to know why you've specified 1/2" BSP male to 22mm compression irons - isn't 1/2" equivalent to 15mm?

    Max heating loop / branch length

    I'm optimising the heating loop a bit on our home as part of a larger renovation and wondering if I'm hitting any design limits on my system, or if this could be considered optimal. This will all be fed by a Nibe F2040-16 (16kw) air source heat pump. The feed/return loop runs as a U shape (22mm...

    Is it possible to use two rads off one TRV?

    Thanks @oldbuffer - the rads are right next to one another (well, about 18" gap, mounted on opposite sides of a corner in the room), so your suggestion that I connect them up seems right. I should probably mention that the rads are K2 900x1200 & K2 900x900, so a total of just around 5kw...

    Is it possible to use two rads off one TRV?

    I'm replacing radiators and plumbing throughout the house in anticipation of installation of an air source heat pump next week. There are two rooms which have double radiators, and especially because I'm using (expensive) smart WiFi enabled TRV valves, I'm wondering if it's possible to connect...

    Mixing 10mm and 15mm with radiators

    Aye, I'd definitely taken note of that - and that's why all the new rads are going in with 15mm. What I'm wondering here is whether I can get by without causing some kind of technical fault by using existing pipework (which will probably be replaced later in the future for the sake of low temp...

    Fixing builders hessian on lime mortar brickwork repair?

    @lostinthelight thanks for the suggestion. Maybe I'm just being cautious, but it seems sensible to cover lime mortar, even in the late summer given winds, unpredictable temp (I'd been told it should be covered if temp gets below 15C) and other weather! Propping a bit of impromptu scaffolding...

    Mixing 10mm and 15mm with radiators

    I'm replacing boiler with an air source heat pump, and adding / replacing about half of the radiators in the house. The feed/return loop plumbing is all 22mm, but while old radiators are 10mm plumbing mostly off a couple brass manifolds, new rads are 15mm plumbing. Will mixing piping in this way...

    Fixing builders hessian on lime mortar brickwork repair?

    I've installed a new soil stack and removed one from another location, and now it's time to repair the brickwork and plug the holes. Its all lime mortar, of which I've now got a bucket, and while I understand how to apply the mortar and help it dry properly, I'm trying to sort out how to cover...
