Many thanks guys that's what I needed to know, but not really what I wanted to hear :( just means some more work turning feed and oulet piping around. Regards vectraguy.

By "service manual" do you mean the little book that comes with the pump and uses pictures instead of words, if so I have read it and still not sure, hence my simple question here requiring only a yes or no. vectraguy.

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...

Sorry m8 I think you have misunderstood me, because the numbers you refer to are not Flexible connectors like the ones in question here, but rather inserts to be used when connecting speedfit pipe to compression fittings. I am not using compression but speedfit to speedfit onto 22mm pipe at...

Could be, but the handbook shows exploded pictures of firstly the Twist and lock version, and next the Standard fittings both of which have the secondary seal at the end of the inserted pipe. They make a big thing about the benefits of having two seals, and unless mine are old stock and have...

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 holty, thanks for your comments, and mine is the first system on this page http://www.diyhowto.co.uk/projects/open-vented-heating.htm Regards vectraguy.

A 3 way valve would be very nice and give me full control with if required heating on its own which at the moment is not possible, without a major job hence the need to have some different control over the hot water via the extra 2 way valve acting as a simple go /no go tank coil water flow...

I assume by "open vent" you are referring to the vent in the F&E loft tank and if so the answers Yes, and the output from the boiler goes to a pump and then to a two way valve which controls heating / water together and water on it's own depending on the manual setting of the Honeywell...

Thanks m8, but using JG push on connections. vectraman.

To be controlled by the cylinder thermostat, and prevent continuous tap water heating beyond the required temperature, without affecting the radiator flow. Vectraman.

Thanks m8, not used them before, and just wanted to make sure. Cheers vectraguy.

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...

Well namsag you didn't let me down, because even as I was typing the post I thought some one is going to say a typical comment, that unfotunately seems to prevail a lot on this forum based on my reading. I have no intention of getting someone in to do the job, as it's a simple cut and screw...

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...

Hi JohnD just had a look and it seems good, but they have "Standard online" with standing charge (lower cost unit rate) and the same with no standing charge ( higher cost unit rate. Which do you recommend. vg

Thanks for the link chrishutt, going there now. vectraguy

Thanks John I will take a look at their site. Cheers vg

Yes JohnD I certainly do, and no I'm with Npower, shortly to change to a better rated supplier. vectraguy

Many thanks chrishutt for your comprehensive reply, and I live in the middle of a five house terrace, with just the wife and me. We don't have a shower,so our main daily cleansing is done with one bath each, and we have a living flame gas fire which to be honest is more for appearance than...
