Hi all , I want to replace my standard towel rail valves with a trv and lockshield as it seems to be running on the hot water circuit instead of the heating circuit. I noticed that the particular one I'm interested in has a max operating pressure of 10bar and a max differential pressure of...

My customer has been online and bought a Telford Tempest cylinder which has come with a control group, tundish, zone valve and expansion vessel. Unfortunately the expansion vessel has no back nut or olive at the point of entry and it seems to be something other than a bsp thread. The vessel is...

Can anyone tell me if there's something like a meers calculator specifically for U/F heating

Has anyone used PVC shower wall panels. A customer has expressed a preference for panels rather than tiles. They would also like a folding shower chair but I don't know if PVC panels would be strong enough. I do know that panels are available with WBP ply cores but I'm trying to keep the costs...

Hi all, can someone tell me why when I apply a finish coat over bonding I always have trouble with bubbling. I'm not a pro but I have done a fair bit of plastering and get on well if I'm finishing over plasterboard, it's just that if I have to bond out first I don't have the experience to know...

Hi all, I am in the process of designing a summer house for next spring and need some advice. My idea is to lay a concrete base of 100mm with steel mesh and then to have a short brick plinth on which would stand stud frames which would then be boarded and clad in plastic shiplap.my question is...

Hi all I have just had a freshwater 6000 domestic water softener installed but the plumber has not commissioned it as he said the instructions for doing so are poor. he has now left me with a softener installed and no water apart from drinking water. is there anyone who can run through the...

Thanks for all you help chaps. As I suspected, just tested the mid pos valve and it's up the creek. Easy fix then. Oh and by the way boys you don't need loads of certificates to tell whether you have any intelligence. I've seen what some of you so called experts have done in the past and it's...

some of you plumbers / central heating engineers are so up yourselves. I happen to be an electrician and have installed the control circuit myself so I know that it's correct because it worked with the old boiler for the last 20 years and I happen to do a lot of the control circuits for my mate...

I've put in my fare share of central heating systems in my time and they've all worked perfectly and I've also got a mate who's happy to certify my work. You don't have to be Einstein to know how heating systems work. so I'll figure it out myself 'PAL'

I did

hi all, hope someone can help. I've just installed a new greenstar 24ri boiler and have hit a small snag. The boiler is a replacement for an old potterton that after 20 odd years gave up the ghost. The new boiler fires up ok when hot water is required and will shut down when the set temp for the...

Ed, I don't have my meter at hand but as far as I can recall it does, if not then I'll bye a better one. I'll be sure to try out your suggestions tomorrow and report back my findings. Thanks so much for your patience guys its much appreciated.

Thanks for the explanation Edward, just one more question. I have a small digital multi-meter, would that suffice or should I be using something a little more sophisticated?

Sorry to sound like in idiot Rf but my knowledge of cross conecting and testing R1+R2 is zero

thanks for your swift reply guys, as to whether I changed any connections in the c.u , the answeris no and I've carried out an insulation resistance and continuity test both giving the coreect results. I've checked polarity by unscrewing the new socket outlets from their boxes and making sure...

Please can anyone help. I've had to move some socket outlets in my kitchen to provide points for new appliances. my kitchen ring main is protected by a 32a b class mcb which is fed from a 63a 30ma rccb. before I carried out the alterations everything was working fine but now the work has been...

I wonder if anyone can help with this question. A customer has asked me to put in a new central heating system, no problem, but hes asked me if his bathroom rads can work independently from the rest of the house. At first I thought about using a three channel programmer and zone valves but this...

thanks for the advice lads. it seems by what you've told me that it would be better and less hassle to have a condensing boiler, but i'm really confused now as there seems to be three different types , the conventional, the system and the combi. from what I've been able to read so far a combi...
