Hi, I've got a dripping tundish on our unvented OSO water heating tank. It started off as quite a flow, which got worse when I turned the TPR valve, but has reduced back to a drip when I drained the system and recharged it following the instructions on the side of the tank. Before I...

Hi, we've got an odd problem with our pressurised system. Kitchen sink and one bathroom basin have next to no pressure/flow on hot and cold, yet shower in the bathroom is fine. Pressure in basin taps in bathroom next to the first one are fine as is a basin downstairs (both these rooms are at...

Hi, I'm slowly completing a shower enclosure. I've got a Grohe shower arm coming out of the ceiling which has screwed into it a 5" shower head (non-Grohe) using a 3/4" (head end) to 1/2" (arm end) adaptor. The problem is, the threaded end of the Grohe arm is only threaded part way round so...

I'm trying to work out which of our household circuits are protected by an RCD. In other installations we've had it was quite clear that individual circuits were protected and could be tripped and then reset individually. In our new place, however, it looks like the whole of one bank of...

Hi, we're thinking about installing a Majestic frameless shower screen once I've built the enclosure to suit it. Problem is this. The tray will be 1200x800 and the enclosure will be built to this size, and then tanked and tiled to the tray. Once tanked and tiled, the relevant dimensions of...

I need to move a radiator on a pressurised system where the 15mm flow and return come off the 22mm main feeds in a position too close to be able to get a pipe freezing jacket on the 15mm sections. What I want to do is freeze the 22mm feeds and then work on the 15mm sections. I've used pipe...

I'm about to lay 20mm elm square edged floorboards straight to hardwood joists. Any suggestions as to the best screws to use - type, length and size? I will drill pilot holes with a screwdigger and then plug before finishing. I usually get screws from Screwfix. Many thanks. crt

I've followed bits of the helpful advice on waste issues and just wanted to check that what I've worked out for our new bathroom is sensible and will work. 1. We have existing bath and basin sharing a 32mm waste out to a gulley at the top of a stack (just waste, not soil pipe). 2. Plan...

Hi, we've got nasty smells coming out of the wastes, principally shower, in our bathroom. We've used drain cleaner and flushed through but the smells remain. The set up is WC waste into external stack; a couple of feet below, bath, washbasin and shower (in that orde) into the same stack. The...

We have a tiny stream alongside the garden and the previous owners had used this for watering the garden by laying a 25/30mm pipe from the stream head and then connecting a hosepipe to it (there is a drop of about 2m from the head of the stream to where the hosepipe is connected). It works well...

Hi, apologies if this has been asked before, but what is the maximum number of phones (corded, plugged-in, not wireless) you can put on a standard BT line? We've got a master socket in with Broadband and a number of additional sockets around the house and I'd like to put in several...

We have inherited with an old house an equally old GEC door bell and indicator system - 240v comes into a transformer and 4v-12v comes out the other side and then supplies an old fashioned bell and the indicator system which puts a flag up depending whether its the front or back door bell being...

I've got an old cast iron down pipe (5"?) which takes the rainwater down to the drain from the roof guttering. I want to connect a diverter for a water butt. What is the best way to do this given that the off the shelf diverters are narrower, metric sizes? Do I: 1. cut the pipe; and...

I'm going to dismantle a built-in wardrobe made from MDF on a 2x2 frame. The screws holding the thing together have been countersunk and then filled before being decorated. What's the easiest way of finding where the screws are so that I can dismantle it without smashing it up? Thanks.

Two problems with a recently installed Grohe push flush (concealed cistern): 1. Flush is too short so doesn't wash away what it ought to. Tried moving the polystyrene float higher up but it hasn't made much difference. 2. Now that I've tinkered as above, when the valve shuts the water...

I'm about to grout some 100x100x10mm glass wall tiles in a bathroom. I fixed them using waterproof adhesive, leaving 3mm gaps. The adhesive manufacturer recommends leaving 24 hours before grouting but I have been told elsewhere that if using glass tiles it is better to wait 48 hours as the...

I posted this a couple of days ago and didn't seem to generate much interest so I'm trying again with a racier subject line. I'm having installed 12v downlighters in a ground floor bathroom. The room directly above is another bathroom, the floor of which is sanded boards which have the...

I'm having installed 12v downlighters in a ground floor bathroom. The room directly above is another bathroom, the floor of which is sanded boards which have the inevitable gaps. From time to time, water spashes out of the upstairs bath and runs into the void between the floor and the...
