Hi, I've painted a wall which looks great when I stand in front of it, but when I stand on the side of it facing the light, I can see several shaded marks. I can't avoid looking from one side since that's where the entrance to the room is. I've added 12% water to the paint and painted 3 coats...

Hi, I noticed one end of these 8mm wall plugs is square; the total diameter is 11mm if we include the square sharp ends Would these wall plugs still make a clean hole into a masonry wall without damaging some of the finishing plaster around it? Many thanks.

It's a 1940's cavity wall and unfortunately it looks like the majority rests on nothing. When looking through the small gap all along and between the sill and the floor screed I could see the full cavity underneath the sill and then the inside of the door step several inches further away...

Hi, A little while ago, when replacing carpet with laminate, I noticed a small gap all the way along the bottom of the wooden front door sill and the floor screed and my view was quite limited (with my head on the floor) to see what was supporting it. So the outside of the door sill rests on...

Well spotted. That must be why the tap feels slightly loose when I turn it. I'm going to take a retaining clip from another gland and fit it on this one. I don't know if it ever came like this or whether the clip came out. Many thanks.

I went to a local plumber and showed him the tap gland, which he inspected by taking the plunger out and put it back again. He said these were the best taps that were ever made and to my surprise he could not see anything wrong with it. But would anyone know why, when I turn the tap off which...

Thank you for that information. I bought a 3/4" tap reviver kit, I believe to BS5412 and BS1010 but the thread of the adapter they provide is 24mm, while the thread I need is 22mm wide. I will continue looking.

A better close up...

This is the picture of the gland I removed from my bath tap, which will fit a so called 3/4" rubber washer, but I find it difficult to find a similar gland to replace my old one.

Thanks for your reply. I am referring to the external diameters of rubber washers advertised on the pack as 1/2" and 3/4" I have measured a so called 1/2" rubber washer, the external diameter is 16mm. There are plenty of these tap glands with those rubber washers on the market (usually for...

Hi, I need to replace one of my bath's tap gland as it takes too many turns just to open and close the tap, and sometimes it can make the pipe vibrate. My problem is, I can find plenty of 3/4" rubber washers on the market but no suitable tap glands. The external diameter of a so called 3/4"...

Hi, Can I replace my basin's threaded tap gland with a ceramic one instead? I can feel with my finger a small canal eroded on the seat but even when I re-grind, it is very difficult to make it disappear, so the seat won't be completely flat and smooth; but does it need to be, if I can replace...

Hi, I've just bought a kitchen mixer tap to replace two single taps on my kitchen sink, so it should a straightforward replacement. However, the instructions mention that I should have non return valves fitted to prevent water backflow. So I went ahead and bought a couple of them. Having...

A final question, if I were to remove the current washing tap at the top and replace it with a check valve would I be able to use the same olive and nut from the short pipe just below it, as long as I put some PTFE tape on the old olive?

I have included a second picture showing the rest of the pipe that connects to the taps. I just wonder, would it be too tight if I were to have both pipes at an 90 degree angle each (with an elbow) rather than curved, with the check valves fitted horizontally, ie between elbows? If not, as the...

Good thing I've asked. Yes, the first pipe starting with plastic is the hot water supply. I've seen a couple of videos and they fitted the check/non return valve (with an arrow on the valve) on the hot water pipe, but for basins. So for the kitchen I will fit it on cold supply, but by doing...

So, on my picture, I suppose I can replace the first bent copper pipe with 2 small straight ones joined with an elbow and then fit the non return valve horizontally, just before the other elbow connected to the tap?

About fitting a non return valve to prevent backflow, all I can see at the moment is an isolating valve fitted just after the stopcock and then the pipes separate, one to the combi boiler to return to the taps for hot water and the other for cold water. I always had 2 kitchen taps before...

I remember reading that building regulations require 1mm per day, so for 90mm you may need a bit of patience and allow 3 months or preferably a bit longer before it is fully dry :). Diluted PVA would stop the dust which will appear when the screed is swept and fully dry. SBR is usually used for...

Hello, I want to fit a mixer tap on the kitchen sink but the metal thread which goes through the sink tap holes are too long, therefore I will need to cut some pipe work to be able to fit it. 1. By hand, how do I undo the straight white plastic connector's top, clockwise or anti-clockwise and...
