Cheers for that Dave. Could the HW pre-heat properly warm the place up through a passing DV? It doesn't just come on for a bit - her flat was apparently at 18 degrees this lunchtime. Pete

Hi Gents, I'm after a bit of advice about a misbehaving boiler if poss. Customer has a Vaillant turbomax combi about 3-4 years old. Works fine, but heating sometimes comes on at random in the middle of the day or early hours of the morning when it's not supposed to. She's had a new programmer...

ok - thanks guys. I've spoken to them earlier and already told them that best option is to replace this ancient lump for a shiny new one so hopefully we won't have to worry about it. Cheers gents...

Hi guys, I've been to look at a job for the replacement of an old (direct) megaflow with a new indirect unvented cylinder. The existing installation is appalling - no inlet control gear, no tundish on discharge etc, etc and the heating side isn't much better. With such a bodgy installation...

I did have a look and couldn't find anything on the pipe. There was an awful lot of crap in the way though so I could've missed it...

Thanks holty - sounds like the stuff. I've used the plasson fittings on blue MDPE but not this black stuff. At the moment the joints are made with pretty standard looking brass compression fittings. Are the c & d converters reducing sets to use old imperial pipe in metric fittings? and will...

Hi guys, Got a situation with hot from a combi and tank fed cold so the customer wants the tank bypassed and cold hooked up to the mains. I come across this more often than I'd hope, but this case is a little unusual. Firstly, massive asbestos tank, so no cutting that up (or even moving...

could be that the wiring diagram is just indicating the need for electrical isolation of the pump for servicing etc. having said that I don't know what pump you've got... eh..? negative head pumps I use operate via integral pressure switches..

Ok - thanks for that guys. You've pretty much told me what I thought anyway. I've certainly never seen this done before... They've had a loft conversion and presumably the builder found it easier to just cap the vent pipe than re-route all the pipework. The customer told me that "he wasn't...

Hi guys, Been to see something I've not come across before. Have to replace a whole house pump for hot and cold water 'cos the old one's broken and it needs to be a negative head anyway. Cold feed to pump comes from cws in loft space and hot from cylinder. The hot comes straight out from the...

I drill through tiles all the time - it's real easy unless they're porcelain. If they're porcelain you'll wish they weren't - you'll have to use a tile bit or one of those diamond grit mini core cutters if you need anything over about 8mm. Drilling porcelain should be done wet or your bits won't...

Well it certainly would look the part... I'm not too sure I'd want to advise it to someone who's not worked with CI soil before though.

Just find your nearest decent plumber's merchant and they'll have it (or get it for you). You're really better off with a fernco though...

You can get space saving bends on soil - look around. I'd rather use fernco type couplings if I were you - they're the rubber collar type with a big jubilee clip at each end. Id also rather just use one at the lower joint and then remake the whole upper part of the stack in plastic. It will...

Yes - flow limiters... Generally people want as much out of their shower as they can get though.

A hacksaw..! you'll be there all day. Angle grinder every time. If you've not played with these before I wouldn't smack it with a hammer - you could do without destroying it. Kirkgas is right to be careful about fire though... and eyes... and ears... But just be careful and protect everything...

Cheers seco - I like 'em too..

Thanks plugwash - I'd pretty much come to the conclusion that that's what we'll do. Handy to know that they are supposed to maintain any earth connection in a satisfactory condition though - might give us a bit of leverage... Earth looks about 6mm2 and it's also dull silver - did they skimp on...

Nice one improver - you've given me quite a good laugh with this... C'mon now - did you really expect anyone to do your homework for you?

Hi Guys, Got a wet room coming up which wants one of these. Anyone else got any thoughts on them? - bit fiddly to set up but seem like a pretty smart piece of kit to me.. Are there any others you might recommend instead - I'm only going for this 'cos I've used it before...
