Yes, but are they fitted into a bossed pipe or a strap on boss. If a strap on boss it should be installed with gap sealing adhesive to completely seal the strap to the soil pipe.

Need to expose first to find out if they have used “strap on“ bosses or bossed socket’s and see exactly where the leak is coming from.

What he may have actually said was, “they had used standard pipe rather than barrier pipe”. Barrier pipe prevents oxygen ingress into the system much better than standard wall pipe, probably the existing system wasn’t flushed properly and the correct dosage of inhibitor wasn’t added. Ive seen...

Agreed, if you’re not familiar with EOL, Global tamper is much easier to understand. If you are only using one zone then that’s pretty straightforward, if you need to link more tampers together I normally use 2 way BT style gel connectors.

Miscellaneous Options 3. Depending on which method you’ve used.

Are the unused zones just linked out or have you put a 10K resistor across the zone terminals as required when EOL is programmed.

My daughter had a Glowworm Ultimate 50 and I managed to keep it going for her over the last 5 years, 2 refurbished PCB, ignition electrode, air pressure switch plus a number of other components external to the boiler. It had been in since the house was built around 20 years ago and was one...

Used the Adey Atom where space was tight, No problems so far.

Never used one but looks like it could be your answer. Depends where you can fit it, ideally before your main isolation valve, then you can remove it, otherwise after and leave the existing one in place and (hopefully) fully open.

Good advice from “oldbutnotdead” regarding tackling the main isolation valve but be aware that unless it’s been altered, there’s a good chance that the incoming main could be lead with the original isolation valve “sweated” onto the lead pipe. Best to strip out and expose what’s what, you may...

If that is indeed the mains cold water supply to the tank it shouldn’t have a gate valve on it, there should be either a stopcock or 1/4 turn valve

Best not to mix components, they are designed to work as a “system“

To completely drain the system you would need to drain at the lowest point / points without knowing how your system is piped it’s difficult to say.

Saying it’s been cut off is being extremely kind, looks more like it’s been chewed off.

looks like a complete bodge, certainly won’t win “plumber of the year”

Depending on what distance you have got you may be able to cut the black soil pipe back beyond the hole where the strap on boss is and fit something like one of these

Looks like very little thought (or skill) has gone into that installation, the strap on boss looks as though it will discharge onto the sealing fins on the pan connector. Or he may have realised that and cut away some of the fins to accommodate the strap on boss thus reducing the effectiveness...

That’s a Hep2o fitting, replace with a Hep2o tee (you will need a plastic demounting tool) some fittings are “grip ring” first and “O” ring second and some are the other way around. Make sure the pipe isn‘t scored where the “O” ring sits or it could weep, make sure y push it on full socket.

Found DrylinePro fixings to be excellent for Dot & DAB walls,

Look like a crimp system and as such will not be demountable, another thing to be aware of is a lot of MLP systems are imported and may not be ”standard” UK sizes, instead of 15mm, 22mm and 28mm you may find it’s 16mm, 20mm and 25mm.
