I'm doing some work under he floorboards soon and as I keep hearing that pipes should be lagged I am considering doing so. However, the upstairs pipes run mostly under the main thoroughfairs and offer a pleasant underfloor heating effect and add to the warmth in the rooms (which have...

My C/H pipework runs in notched out pipework under the floor boards and is not clipped. Originally is was kind of clipped using crossed nails and hessian for protection but I noticed it was wearing a hole in the pipe so removed them. I decided to leave the pipes floating as there seems to be an...

Hi. I have a gravity fed heating system and am trying to figure out if the feed and vent are in the right place as I've noticed the feed gets very hot, right the way to the upstairs ceiling where as the vent remains cold. The vent and feed have been put within 150mm of each other just before the...

Thanks Matt, you're a gent. Great instructions and easy to follow. I can say without looking that the feed from the pump splits, it's immediately before the valves and is one of the reasons there is restricted movement in the pipe work either side of the valves. I'll run the other checks to...

I had to cut the pipe to get the old valve out and even then it was tight. I didn't know there was a refurb kit, that would be the best solution, I'll track one down. I'm not sure if my local plumbers merchants stocks them, they didn't have them when I was there last week - I don't earn...

Which type? 28mm 1" BSP (female thread) zone valves ? Unfortunately, the internal diameter of the valve body is to small for an olive and fitting, the tube only just clears the thread - I was told they were intended for use on iron pipework - after I had got it home and tried to fit it...

As I understand it, chlorine reacts with certain plastics to form polyphenols responsible for the TCP flavour. I have a 1 barrel brewery and it can be a big problem for brewers. I don't know how long polyphenols typically take to form, I suspect it depends on the plastic and chlorine levels...

As I said earlier, they aren't the standard 1" bsp internal female thread or internal compression fittings for 22mm tube (they are fitted on 28mm tube). I have tried that one. These have a finer thread pitch, possibly a manufacturers own thread which isn't available from on any of the...

Can anyone suggest a work round ?

Hi, It's a Honeywell and is almost identical to Honeywell model V4043H 1080 1" (bsp) zone valve 240 v except with a different female thread. The model no' on the head is: 40003916-001 Without the power head.

Hi :D I have a pair of 2 way zone valves controlling my heating system that I would like to replace. They are OK at the moment (touch wood) but one squeals a little and the other has a power head that slips occasionally. They are similar to these Honeywell valves...
