concrete

Hello. Looking for a little guidance. Basically had a plumber install new ch system and radiators. He ran pvc pipes (2 22mm, 2 15mm and 1 copper gas main) with angle bends under the concrete floor. We’re now replacing the floor as it has no dpm or insulation and have found none of the pipes...

Had a repair done by insurance company's own appointed contractor to a galvanised pipe under bit of the short concrete path between the road and my front door, two months ago. Seems like the repair has failed as water is pouring out on to street from under path and surfacing on and around the...

Has anyone come across anything similar. Sorry there are so many questions. Many thanks in anticipation. My daughter has moved, 5 weeks ago. The previous owners had a hive system on the Worcester-Bosch combi boiler. They replaced it with a hive thermostat and my daughter eventually got it...

At the base of some cast iron soil pipes? Seen it on a few but not actually sure the reason why.

hi guys, I went to a job today and removed a gas fire and solider a blank on the gas pipe. It was a false floor concrete with battens with finished timber floor. is this classed as a unventilated void? I've looked at my gas book and it only classes apartments to have added ventilation in voids...

Hi all. Does anyone have a manufactured system they use or make up their own out of plywood? Seen some ducts in BES but at £16 + vat for 3 metre is expensive and then you need to cut the ply top. Can kuterlex plastic coated copper pipe be buried in the screed without insulation or ducting...

Hi, I am wanting advice on what is permissible with regard running a gas pipe under the concrete slab of a garage. To give further info, we are building our own house with a integral garage, we propose to have the gas central heating boiler in the garage, towards the back, the gas meter will...

Feel free to mock me for my lack of knowledge, but if you can provide any advice whatsoever, it would be most appreciated as I want to learn which is why I'm asking these questions! When laying a waste pipe in concrete ground floor as a retrofit (for e.g. a shower tray), I can see see potential...

Can anyone recommend a decent pipe detector to detect pipework in concrete floors - I need to chase a pipe this afternoon and don't fancy chasing through other pipes!! Or if anyone can recommend another way??

Want to pick your brains. Having a extension done on the kitchen and wife wants to swap the living room and kitchen around so that living room faces the garden. Soil stack currently in corner of kitchen and can't be moved as all services are at rear of house. From the soil stack to where the...

I have a leak coming from under the bath and is coming through concrete floor/wall egde. When the boiler/heating is turned on it temporarily stops. The heaters are now slowly stopping to heat up. When the water mains is turned off, it stops but this is not practical as it turned off the upstairs...

Hi guys, I was wondering if you could provide some guidance dealing with a very difficult situation I'm in. Some of you helped me with another issue (broken drain pipe) here: http://www.ukplumbersforums.co.uk/plumbing-forum/94058-broken-cracked-sewerage-pipe-garden-options.html#post913865 It's...

I'm a builder rather than plumber so hadn't used core drills until now. I've bought a Dewalt D21570K which was recommended by a plumber. I went on to buy a set of Dart drill bits. Both items weren't bottom of the range but not far off. I only needed the drill to make three holes hence the...

Hi, I am a relative newbie to the site. Following my last post it seems we've got a leak underfloor with the CH pipes set in the concrete slab of our bungalow. The boiler pressure is dropping from 1.5 bar to zero every 24 hours. As there are no visible sign of leaks anywhere to be seen in and...

Hi, I am new to the forum. Hopefully, I can get some advice regarding the Combi boiler / CH problems in my bungalow? The pressure keeps dropping every couple of days. I have BG out to try and fix (they've been out twice in the last week) They are suggesting it's either the heat exchanger or...

Boiler on the other side of wall A. B will be a washing machine. C will be a rad. Orange dotted line is a partition wall. All brick/block walls will be dot dab. Concrete floor of extension is 75mm deep on top of insulation, the rest of the room is suspended timber. Best way to get a 15mm...

I know that wet cement/concrete can have a reaction with copper and begin to attack it, so we sleeve it, but can dried set concrete still have any affect on copper pipes installed later on?

I'm buying a new flat with all concrete walls and floors. The pipes for the heating all run exposed at the base of the walls. The contractor suggested burying them by trenching out the floor and covering them back up with concrete patch. The current pipes are standard plastic with plastic elbows...

Hello forum. First time user here (and now registered)! Can someone please advise the best/recommended method to protect 15mm copper pipes that I will be setting back into a wall to feed radiators in my house. I've already chased the walls, which are standard concrete blocks, but I'm aware of...

So judging by the other thread I started I'm going to struggle to connect a new toilet with my waste pipe hole being so far from the wall (about 30-35cm to be precise). I am therefore thinking about the logistics of moving the opening. As the title suggests, it is a ceramic/clay/earthenware...
