Help needed badly

[vectraguy]

Hello again Goldberg,

it's very likely to be 1", so you just need a 1" BSP socket to connect the male SF to the cylinder.

I hope that so, and I have found a source of such couplers.

However, be prepared for the dip tube not to work entirely as designed, because it will be at least 1" higher in the water than intended.

Yes this had occured to me and would tend to spoil some of the advantage,and regarding the Essex that sounds a bit too much for me, but I appreciate your comprehensive description of it.

The beauty of using a flange for me is all of the hard work siting and connecting the Grundfos 15-90 will not need changing, as you will recall from early in the thread the pump worked fine until I realised it was also pumping through the header tank vent.

My intention now is to cut the vertical pipe which feeds the HW downwards and the upward vent and fit an end stop on the top of the T junction, and then fit an elbow to the up pipe from the vent output of the surrey flange thus achieving two seperate outputs un affected by each other.

Your comments please

Regards vectraguy.

Personally, I wouldn't use an end stop above the tee - I'd either change it to an elbow, or fit a manual vent to make it easier to prime the pump.

Also, you might want to fit the flange before committing to any particular choice of pipework leading away from it, because it's quite hard to predict exactly where the horizontal outlet from a Surrey flange will point when it's done up tight.

Sorry to keep introducing more alternatives, but if you absolutely have to line up the outlet with existing pipework, then a better bet is the Warix flange.

Anyway, I think you have the principles covered, and you sound more than competent, so it merely remains to wish you luck with the job - please post the result on the topic so we know how you got on.

Yes that sounds better and I think speedfit elbow on both the up and down pipes and remove the T altogether.

Sorry to keep introducing more alternatives, but if you absolutely have to line up the outlet with existing pipework, then a better bet is the Warix flange.

No need to apologise my friend your help is very much appreciated, and on completion of the job I will return to the thread with a blow by blow report.

Hi vectraguy

Blow by blow is my favourite type of report, so I look forward to the experience

Well Goldberg just as things were starting to look up on this job it's all gone wrong again.

Today I went to Plumbase merchants, and was pleased to see they had a female to female 1"bsp adaptor to make my Surrey flange into a female connection onto the cylinder top.

I got home anxious to put the bits all together, but heres my latest problem.... the six inch water probe is not mounted in the flange center, but offset right against the inner wall of the male threaded bit.

The 22mm pickup probe is tapered about 1/2 inch below the thread bottom to allow screwing into the fairly thin cylinder top entry, but because the straight coupler is 3cm long it wont even get the thread started due to very tight contact.

I had even worked out how 3cm of 22mm pipe could be soldered on the probe end to compensate for the depth of the coupling raising the suction level.

Regards vectraguy.

It now seems my last resort is to buy a York flange, as seen here

http://cgi.ebay.co.uk/1"-Female(-Fi...vr_id=&cguid=7cf2bb6d1200a0e204216801fffd5bac

This also appears to have a F TO F coupler but it's hexaganal, and musn't be as bulky as a standard coupler, but it's still has an assymetrical pick up tube location.

Hi vectraguy

Things are never straightforward, are they?

You could buy a 1/2" Surrey flange and a short bush to clear the socket, but if you're going to do that then you might as well but a York flange.

is that your proffesional opinion

Quite so Goldberg, and that's now my intention, hoping the torture will then end, any way keep in touch and I will update again on receipt of the York.

I,ve learnt a great deal from this situation and not just about plumbing

btw went into the plumbers merchant this morning and the counter guy wanted to know what I was doing, so I told him the whole story (bet he wished he hadn't asked) and a plumber next to me hearing it all said " You don't need to do all that, just blank the top of the flow/vent T and cut off the vent pipe and reconnect it to the input side of the pump"

I asked him about the pump sucking in air, and he claimed that will be no problem, I'm sure he's got it wrong but I wouldn't argue with a plumber, after all when I retired 11 years ago I was an Electronics engineer.

I'm not as sure as you that he's got it wrong - I spend most of time correcting things that the original installers would swear was "no problem".

The thing is, it's far easier to do a job right than do it wrong, and I have no doubt that you'll successfully install your York flange and get it working.

and your job is oh clever one

apart from pedantic git who knows nothing exept how to quote regs and then can't admit he was wrong

Vectraguy,

There is another solution to all this, look on the Salamander Pump site at their S-Flange.

It is the same as a Surrey Flange but comes with the option of either connecting to male or female cylinder outlets.

Hi Rico99 that looks just the job to me, wonder why I hadn't seen that sooner, and it has got the same hexaganal adaptor for male to female as the York version.

I cant really tell from the pic if the pickup tube is dead centre, but I suppose it must be.

Thanks I will now go to the site for details.

Regards vectraguy.
