Tried the endcaps in hot water and that seems to work with all the 10mm pipework. All four runs are now holding pressure. To be honest I don't totally trust the dry test gauge that I have, it could be leaking. I completed my 22mm/15mm bathroom pipe runs to shower and sink etc. and just bit the...

Yes that sounds like good information. I will try the warming the endcaps in warm water and spinning the endcaps before testing. Will report back with the results.

Also just noticed that the pushfit end caps I am using (John Guest) have a minimal working temperature of 20C. All my testing has been done at temperatures less than 10C and even below 0C overnight. Would this cause the endcaps to slightly leak? Regards FarmerJo

Got some spray and applied it to the copper work and so far found no leaks. I have added some additional pipework and one of those runs are also leaking. I did discover that some of the 10mm end caps were leaking when tested in bucket of water. Just out of interest, are pushfit endcaps a good...

Yes I like the leak detector fluid idea. Going to get some now. Thanks.

Yes I did wonder about the temperature. In my case (very cold house at the moment), normal daytime temperature is quite low. When I started the tests it was probably about 5C and went below this overnight. Its about 3.2C now. During this cold snap I suppose the temperature could get to about...

Hi, I have done some copper pipework for the flow and returns runs for my central heating system. The overhead runs are 22mm and I drop-down in 10mm microbore to each of 5 radiators. The 22mm run is about 20m long and the first 10mm connection is about 15m along. First I air pressure tested...

I am assuming that the joists are also OK for the plasterboard and plaster top coat. The weird thing is that I removed a section of my craw way at one end of the bungalow to ensure that there could be no additional weight on the joists forcing it to sag. Although this reduced the sag by a...

Hi, I have a bungalow that uses trusses that have a 6m span which are spaced apart by 0.6m for a total length of about 12m (about 20 trusses). Each truss uses 4 webs/posts in a 'w' formation. Forgive me if this is not the correct terminology. The trusses are made from 72mm x 36mm timber. The...

Wow that has given me a lot to think about. Many thanks for everyone who has taken the time to help. Much appreciated. I think that perhaps instead of using earth rods I will choose a more robust harder wearing alternative since I already have the pavement removed from all away around the...

Great help so far. I have some additional information which I should have included initially. There is no gas pipe to the bugalow, just water and oil. The water pipe is plastic and the oil pipe is copper and just goes to my own oil tank about 10m away for heating purposes. The oil pipe is...

Hi DIYnot, I have a bungalow that is out in the sticks which is connected using TNC-S. The cable feed is a combination of overhead and underground and must be about 300-400m from the tranformer in a garden nearby. I considered the case of a loss of the incoming combined TN which could result...

Hi Madrab, Now I am clear on exactly what needs to be done (just gotta do it now). Many thanks for your help and patience. Best Regards Farmer Jo

Great advise and I will change to 15mm radiator pipework and have ordered some Fernox inhibitor and manual air vents. I have one last question. Would it be OK to run 15mm pipe from the 22mm flow and return pipes so that I can get them close to the loft hatch. They could either be on a slight...

Yes I like the idea of the air vents being near the loft hatch. Is it OK to run a 15mm elbow from the top of a vent and length of 15mm pipe to get it near the hatch? Regards FarmerJo
