If the house was plumbed with pushfit when built it should have been pressure tested at first fix. Depending on the make of pushfit there are different test requirements, if ‘O’ ring first (polyplumb, old style Hep20) there should have been a low pressure and high pressure test up to 18 bar...

I have just changed my Hikvision 3mp IR cameras for Hikvision ColorVu 5mp version, these give excellent daytime recording and Colour at night which is also very good quality and far superior to the standard B/W infrared. A mixture of 2.8 and 3.6mm lenses cover my property fine.

and that the plastic pipe hasn’t been scored where the “O” ring sits

Thanks, I’ll see if she can sort it from that

Hi all, my daughter has just recently moved into a new (To her) property that has an old Neff dishwasher installed, the previous owner has left no instructions. The front panel is very worn and you can’t make out the numbers / symbols around the knob, I’ve searched for a manual but with no joy...

Whatever the quoted output it will be a lot less when you have numerous towels and garments hung on it. That’s why when my daughter said she wanted one I left the existing radiator (with TRV) fitted connected to the heating circuit and plumbed her new towel warmer into the Hot Water Primary F &...

UPDATE. Remote playback has started working agin today.

Nope, deleting and reinstalling the app didn’t work either

Thanks for the reply, gone through several automatic DST changes without any problems in the past. Firmware’s all up to date phone, app and DVR. Rebooted DVR and Phone, no joy. Might uninstall / reinstall app. Thanks again

I have been using Hikvision CCTV gear for years without any major issues, I have 2 identical setups at different properties. DS 7204HUHI-K1 DVR with Hikvision camera’s, both set to automatically change the hour (DST), which they both did last night. When viewing on iPhone or iPad live view...

Good practice is to mark the pipe with the socket depth so you know that the pipe is fully home then pull back on the pipe to ensure the teeth bite, in reality this doesn’t happen. You can always double check by pushing on the pipe to see if there is any movement but if in full socket you should...

The reason polypipe say 18 bar for polyplumb is that is an “O” ring first fitting, this means that when the pipe is inserted into the fitting it passes through the “O” ring first then the “grab ring” second. If not fully inserted the “O” ring can hold the pipe when the pressure is increased even...

Both the Speedfit offerings that the OP was looking at are Barrier pipe, he was asking the differences between them which have been pointed out, so with them both being barrier that wasn’t one of the differences. You are correct in saying that Barrier pipe should be used on central heating pipe...

They are two completely different types of plastic and you can use either. The PEX pipe is far more rigid and if using from a coil it can be difficult to use as it always wants to return to its coiled state. Polybutylene is far more flexible and the “Layflat” is much easier to uncoil and use...

The soil pipe is also the vent pipe (normally) so won’t have a trap on it. It will vent to atmosphere above highest window level. (Some May have a durgo valve in the roof space. All appliances, WC’s etc entering the soil pipe will be trapped to prevent any foul air escaping into the property...

Check that the black flexible hose going into the HepVo valve isn’t too long, if it is it could hold the membrane open and allow smell through.

Acorn was originally brown (Before it became Hepworth) but was polybutylene and Push Fit, this stuff is more rigid and doesn’t age well.

Some of the old solvent weld plastic becomes so brittle you’d be better off ripping it all out and replacing with copper or Hep2o. Once you start disturbing it you can open a real can of worms. I recall a whole estate in Runcorn had it all replaced because of problems.

I think it’s because plastic is an oil based product, some jointing compounds are oil based therefore could degrade the plastic pipe. For the same reason they say not to use oil based paints if you paint the pipes.

Plastic pipe manufacturers say not to use and type of jointing compounds, copper olive with PTFE tape if required. Check if ok to use on plastic.
