Hi All, I am just about to start a job in a very high end apartment block. One of the first things we need to do is fit a temporary hose tap for the site. The Landlords Tenants Agreement states that if a hose tap is to be installed, it must be fitted with some kind of valve/meter that will...

Good Evening All, We have a gas pipe running through a ceiling duct. The duct is 0.3m x 6.0m so to my calculations, the duct has a cross sectional area of 1.8m2. This means that we need to install a vent with a minimum of 0.05m2 of free area. (Please correct me if you believe that any of the...

I know you all must be sick of nest wiring questions but just wanted clarification if anyone could help me please. Here is what I propose. 1. LNE from 3 amp fused spur to boiler power terminal. 2. 2 core from L & N on boiler power terminal to L & N on heat link. 3. 2 core from 24 volt RT on...

Good Morning, I have been asked to price a job where there is no gas available and no space for the storage of any fuel. The client has asked for electric combi boilers to be fitted. I’ve never fitted one before and wanted to see if anyone has any recommendations on make and/or model and if...

I’d be grateful if anyone could offer any advice on this. I am aware that under Part L regs, any dwelling over 150m2 must be split into at least 2 separately controlled central heating zones. Does anybody know if this is also the case for non residential? I am currently pricing a community...

Morning All, I'm trying to cut 2 branches into a 65mm (2.5") LCC cast iron down pipe but I am working to 2 fixed points. Does anyone know where I might get a cast iron slip coupling to help me out. I know I could use a flex seal but it is all in show and the company we are doing the work for...

Morning All, I have recently fitted a couple of urinals fed by a cistern in the loft space above. The cistern is fed by a basic petcock. However, the siphon never actually flushes, the cistern just keeps filling and eventually just starts to run down the overflow. I have tried changing the...

Hi guys, Can anyone tell me if it is possible to do convert an open vented system currently fitted with a Potterton Kingfisher 2? If so, I know how to do it, and the risks involved. I just wanted to know if it's feasible as I know that there are certain parameters on sealing systems with...

Has anybody here fitted one of these systems, and if so, is it as much a massive pain in the a**e as it looks. We have a job where the client wants to use it. I've watched the instructional video on YouTube http://youtu.be/6Z_Zder-KCw But it always looks easy with a nice square room...

I've never been told that this is the right way to do it but it just seems to make sense. What is everyone else's view on this? When running central heating return pipework, we always try to configure the tees into the returns so as to not have 2 returns coming from opposing directions...

Bit of a boring one guys. I need to get some sort of portable device for printing off solid plastic valve tags on site. Ideally a circular tag with a hole at the top for a chain, wording embossed into the plastic. Any recommendations/ideas where I might get hold of one?

Hello all. I am currently pricing a job in a flat. We need to run a 42mm gas supply from the meter, which is in the basement, into the flat to supply a combi and gas hob. Once we are into the flat, we will fit a secondary ecv and reduce to 28mm pipe for the remainder of the run. I am...

I run a small plumbing firm (4 guys including me). One of my guys who started as an apprentice and has been with me 5 years has had regular pay increases and has asked for another. He is PAYE, gets 25 days a year holiday, has his gas safe registration (under our company name), gets picked up...

Hi, I have a VW Transporter Van (08). In the last few days every time I turn on the heater/blower, it runs for about 2/3 minutes then slowly dies out. When it dies, I turn it off for 5/10 minutes then when I turn it back on it repeats the procedure, on for a few minutes then dies. Does anyone...

Hi, Do any of you guys on here have your MET 1 ticket? I have a gas sub meter which I need to be installed in a property in central London. Please let me know if anyone is interested. Thanks, Dale

Ok, this is going to sound like a strange one. But I would absolutely love a straight forward yes/no answer. If a Vaillant 937 is piped up with cold mains going up the hot and the hot coming out where the cold mains should go in, I obviously know it won't operate correctly, but could it cause...

Hello, I am working in a flat with communal heating from a large boiler which does the whole block. I currently have 22mm flow and returns in the flat I'm in with isolators so I can work off of them. The customers wants a programmable room stat to set on/off times and obviously gauge the...

Good day all, I have a large cold water storage tank I need to replace on top of a block of four flats feeding cylinders and down service to all flats. Currently the mains feed to the ball valve comes up out of the floor in lead pipe and this is where I will need to connect onto it and run...

Has anybody used one of these yet? http://www.plumbcenter.co.uk/en/bathrooms/showering/shower-pumps/salamander-home-boost-mains-pressure-booster-pump-287078 I thought pumping mains was illegal?
