1/2" stopcock connector issues

[HopperFish]

Hi folks,

I wonder if you can help me, I live in a small block of flats around 40-45 years old, in the bin room there is a short pipe with a stopcock on the end of it and thats it. the tap is marked 1/2", since the old bodge of a load of plumbers putty on it didn't last long to get a hose connector to fit i am after something better.

The first problem is a 1/2" hose connector is very tight on it, it will thread or at least seem to but on a hose connected to it and it comes off and you get very wet while trying to get to it to turn off.

The threads seem ok on it so either the thread is not BSP, which I seriously doubt, or there is something i am missing so anybody have any suggestions? would a metal hozelock adapter be any better than the cheap plastic one I have have tired a proper hozelock plastic one and that didn't fit either.

The thread is different for some reason and nothing is going to screw on at all? would a fitting desgined for a compression fitting be different?

since this may be old imperial pipes etc am i right in thinking the pipes are going to be 12.7mm, so the hole for the pipe wont fit a 15mm pipe.

so apart from get a plumber to come and do something which is going to cost at least £100 quid does the following sound like a good plan.


could i solder something to this? since it is brass and need a lot of heat it could ruin the seal and then would have to faff around telling the block of around 8 flats i need the water to building turned off for a while?

Any idea on a fix i can do will be handy, if not anybody from Aberdeen know a good plumber that will do a proper job and not a cheap bodge?

I'm struggling to understand what you are trying to do. But i am guessing you are trying to connect a hose pipe to wash the bin area. You say the hose keeps blowing off. Could you not use a jubilee clip on the hose to stop this? This would be the easiest solution rather than replacing the tap or trying to find the correct hozelock fittings. Sorry if i have misunderstood! A picture would help.

Ps hozelock do sell 1/2 inch adaptors. Has someone tried to seal a 3/4 inch adaptor onto the 1/2 inch connection using putty? As i said, post a pic!

Sorry it was very poorly written,

this is what i have to work with in the photo, I can't screw on a not hozelock type adapter on to use a hose since 1/2 is too tight 5/8,3/4 to big, the hose is to wash binroom, my car etc so needs to a good strong fit.

You'll need a nut, olive, bit of copper, 15mm male iron and from that your half inch hoze lock will work.

Finding a suitable nut will be the hardest bit.

It were me I would get an new 15mm lever valve and snatch the hole stop cock out.

Will get Blo0dy wet shifting the remaining olive though

That is what i feared, any idea on the nut I would need? am guessing an old one from stuff of a similar age?

I admit its a bit of a bodge but if you use this and tighten it well it should be water tight and pretty sturdy.

Cheers guys, I did try one of them in the past but it wasn't very good leaked a lot when used with a pressure washer /hose adapters, may even still be in the house somewhere. Mighty try it combined with some silicon sealant as well, and a proper jubile clip.

It looks like an old Prestex stop tap with fine thread.

I still have some fittings for lead to copper with same thread.

 

[HopperFish]

will have a look and see what I can find for lead/copper fittings, should be able to find something suitable, if lead used a fine thread

Lead don`t use a fine thread - it`s the old Prestex fittings that have the fine thread - all of them , including copper/lead unions

Ah ok i'm with you now, couldn't find the old rubber adapter that I had so got a new one coming from ebay and will pick up a proper jubilee clip, and use a little silicon sealant/glue to help it stay.

It should hold, its not exactly massive amounts of pressure it has to deal with, I just want to use my pressure washer to clean car etc and a plumber would charge a lot for a proper job.

Could you turn off the stop cock in the street and rip this old one out and fit a new 1/2 inch stop cock?
If you do it quick enough, the other flat tenants won't notice they haven't got any water!
