Hi ebee Trouble is they never have supplied an earth terminal, ever, which was really the cause of the problem in the first place. We'll see what happens. Cheers Martin

Thanks Adam and RF for your words of caution, I have heeded them. When I speak to SP tomorrow I'll stress the age, need to upgrade etc, and see where that gets me. With a bit of luck they'll decide it needs changed, here's hoping. I'll let you know the outcome. Thanks for your help Martin

RF wrote Yes isn't it. On the front is Aeroflex Fluvent Hope's Patents. It also has cast on the front G.C.E.D, Glasgow Corporation Electricity Department, which suggests it was made to order for the corpy. Since the South of Scotland Electricity Board and I came into existence in 1954 it's...

I guess this is the accepted albeit bad practice. I must admit the thought of sweating an earth connection onto a live cable, given the melting point of lead and solder isn't much different, isn't that attractive. No doubt about that, but the other option of TT isn't much of a goer because...

Hi RF picture is here http://i62.photobucket.com/albums/h113/martin43_2006/IMG_0999.jpg

Adam Thanks for your thoughts. Bearing in mind this installation dates from the 1920's, and was possibly DC originally, earthing via the water pipe was almost the universal way of doing things then. Also all water pipe then was cast iron so a section removed wasn't that much of a problem...

Hi all Discovered today that my installation isn't earthed! This came about as I sorted out what needs to be done for a new CU. The existing CU main earthing conductor is connected to the copper water supply pipe under the floor, which unfortunately becomes plastic before it leaves the...

I would venture to suggest that the problem is more than likely to do with the recording equipment and it's grounding, which may or may not be at earth potential. The usual practice is to provide a technical ground star point which is then connected via a single cable to earth. This should be a...

Stuart Basic problem is lack of head from tank to shower, ceratinly no more than 0.5 bar which is frankly inadequate for an electric shower, even allowing for the pump. What size is the pipe from the tank? The only long term fix as others have suggested is to run the shower from the mains...

Stuart Which floor of the tenement are you on, which part of GLW? Almost certainly not furring in my experience, waters far too soft. Martin

Thanks to everyone who gave their thoughts, it was most helpful. I have decided that the best course is to wait until the boiler needs replacing then convert the whole lot to a sealed system. Martin

Thanks for that Chris, understood now. TRV's on all rads, boiler controlled by stats and valves. It could well be sludgy, however there is no problem with any of the rads heating up, even the last one on the system. Do you think the difference between the static and dynamic head and the height...

ollski v good idea, however the cyl was replaced 4 years ago so its still quite new, in turn it replaced a primactic so i could add inhibitor, also to provide balanced supply for mixer shower. Boilers ancient as well, see below. Chris R Boilers an Ideal E type RS at least 9 yrs old...

Thanks for the suggestion Jo, but after a further study of available space to get additional pipework in without rebuilding the kithchen, I can't. It's really only come about because the DHW storage temp is too high during the winter, and whilst other works are going on it seemed an ideal time...

Thanks to jo and soggy for their helpful info. Can I do the following, move pump to the boiler flow, provide new vent teed in between boiler and pump, retain existing F&E teed into cyl ret. I appreciate it's not wholly satis but there is a problem in getting additional pipes into the duct up the...

Hi all I wonder if the heating engineers could assist me. I am fitting a cyl stat and 2 port valve for the DHW. The boiler is in the coal shed as is the pump (in the ret). F&R are teed, one side goes via the grd flr then upstairs and feeds all the rads. There is a 2 port valve in the CH...

Thanks for the suggestion, I've been round this loop already. Multikwik do a universal coupling for plastic to clay, CI, but it's meant to be inserted into the ID of the pipe rather than the socket, which makes it to loose. Unfortunately the branch is not long enough to cut off the socket, even...

Hi all I've read a bunch of the posts on soil stack problems which all seem to point in one direction, however I would appreciate your collective thoughts. The problem is this, the WC was connected via the original lead pan connector which turned 45 deg and was soldered to a brass ferrule...
