These suppliers don't give a fig about Part L. they only interested in shifting stock. This company has probably bought a container load of crappy valves from China and is bundling them in a competitive package. To follow you argument Pedant, are you saying they should be giving solder...

I agree "you get what you for" but there seems to big difference in price for from different installers using same quality boilers on new installation. A friend of mine recenlty gave quote of about £3900 to install Valiant system 6XX ( 100,000 BTU bolier) Vailaint UV cylinder 150L 13 rad...

I've plastered small walls and sections of a wall and I seem to get a reasonable finish. Now I am looking to plaster a rather large ceiling 14ft by 12ft. Can anybody give me some tips please? Do you put the first coat on all the ceiling before applying the second coat or do you apply it...

Jason Can you explain what negative pressure is? I don't understand it. Is it pressure in a different direction

Depends on your budget amongst other factors. Bacho's listed the top of range boilers At low end, look at Heatline and Ariston MicroGenus

I am sure somebody ( might have been ChrisR) posted a list of the items that they check when carrying out a Full services in earlier post Webmaster - why was this checklist removed ? ChrisR – if it was you posted the list, can you please repost it

After heating it, hit it gently but firmly with a hammer, then attempt to tighten it before loosening it. This should do the trick

bahco That's exactly it. I have few 25mm x22mm stop cock with 25mm olives missing. I have replaced my dad's lead supply pipe with MPDE used a 25mmx22m stockcock. Seven Trent water connected for Nowt and if I might say they even commended me on the installation. Now, MY brother in LAW...

I need a few 25mm olives but I can't anyone who stocks them

I just posted query about 25mm olives and it appeared for a minute or two and then disappeared?

This question seems to come up regularly and it like saying which car should I go for ? Most of the installers have their own preferences for one reason or another (Easy to install, good tech advice, no comebacks on previous install, spare parts easy to obtain and not expensive etc)...

Are sure this boiler is only two years old ? I thought, and I maybe wrong, that Valliant 242s were superceded with Turbox Max 824. Can we have the full model of your boiler ?

I thought most plumbers/heating engineers used Bedrooms BTU = width/ft x length/ft x height/ft x 4 Living rooms/Bath BTU = width/ft x length/ft x height/ft x 5

PVM - Your're right I don't get it and hence asking the original question. I am still unclear whether a flue analyser is required to set up the condensing boilers I do have sympathy with your situation- i.e. you have fork out an additional £400-£600 on a flue analyser to install boilers...

PVM Have you fitted any condensing boilers for your customers? If so, Which ones and does it not mentionin the install guide to check and set CO2 content if necessary As a few people said to my original query follow the manufacturers instructions. I take it you do check gas inlet working...

Needless to say the customer is being ****. Maybe an idea to contact the boiler /EV manufacturers to see if they have any stats on EV failures over period of time for example 50% fail after 9 years use. Perhaps the professionals on here might have some crude stats, some thing along the...

I can;t comment on Rav85T but I had RavenHeat 820/20. IT was certainly wasn't designed with the engineers in mind. The parts are in awkard position and are difficult to change Within fours I' had to change the 50 Ohm Resister, Diverter Valve and Thermocouple. The isolating valve on Flow...

I have never done any gaswork for reward or gain and I don't intend do either. However, I do have an interest in doing my own DIY work. Now it looks as I won't be able justify spending a small fortune on Flue gas analyser, I shan't installing a condensing boiler unless I can borrow one from...

Sound's as if the spindle in the diverter is not moving freely. May need lubricating with silicon grease. The Diverter in the Raventheat is bu**er to take out. It is at back and expect the skin on the knuckles to be scraped, unless you have small hands.

Hi Breezer I do mean CO2. As I understand it this needs to checked/set for condensiong boilers. Of course a flue analyser is handy for checking excessive CO emissions which should when servicing appliances.
