I have just fitted a Honeywell 2 way valve to my vented system, but the original system installer had fitted the feed pipe and return pipe to the cylinder water heating coil very close to the 2 way valve which meant it was impossible undo the 22mm nuts to the valve, and all of this is under the...

I have just purchased 3 of the above from my local market to replace the ones on my radiators which are looking a bit tatty. They are absolutely the same in appearance, but these have a small plastic box attached by a piece of uninsulated wire, and I need to know if the extra unit can be cut...

Hello all, I need some info about a motorised 2 way valve which is going to be used for a non central heating application. My question is, when the motor is energised and the valve either closes or opens (depending on the type) does the motor remain energised even though the the job is...

I am fitting a 22mm lever ball valve in place of a gate valve, and the piece of pipe at one end will have the retained 22mm nut and olive, will it be ok to screw these onto the new valve which has exactly the same pipe entry. Regards vectraguy

As above I've got a couple of questions. Regards vectraguy.

I fitted the new Grundfos 15-90 boost pump to the hot water cylinder output, and all went well or so I at first thought, but the large cold water header tank was being filled via the vent pipe, and this has stirred up all the clag and the water is coming out brownish. My main first concern is...

I've just received this new pump, and it looks as if all my pipework planning has been a waste of time because I have arranged for the input to the pump from the HW cylinder to be at the top and the output at the bottom which I thought made sense. Now looking at it there is an arrow pointing...

I've just purchased an FLX26P Speedfit to Speedfit flexible connector, and looking down the barrel (so to speak) I can see only the main 'O' ring but in the JG little hand book page 9 there is a picture of the innards which shows a secondary seal at the pipe end. Mine has only the main O ring...

Hello all, I'm going to fit a two way motorised valve unit in the cylinder top input 22mm pipe, which is fed from the F+E tank in the loft, and I would like to use one bung in the vent and one for the cold feed. I've read the bungs work ok on radiator valve replacement, but not sure if they...

I have a fairly old ,but perfectly working gravity pumped system, and would like to fit a 2 way valve to control the hot water cylinder from becoming too hot. The cylinder is contained in the upstairs airing cupboard, and I intend fitting the valve unit in the short length of horizontal 22mm...

I have recently had my 25 year old boiler replaced with a new condensing conventional one, and decided to monitor the meter readings at 2200 every night for 3 weeks. The heating and water have two periods a day, namely 0700 to 0900, then 1630 to 2200, there are 7 radiators, and a hot...
