28mm overflow into garage!!

darrude · 30 Nov 2016

Hi,

I have moved into a new (old) house, and it has a system boiler. The water tank is next to the garage with the overflow just on a down pipe into it. There is quite a lot of run off on this and the previous owner has fudged a hose pipe onto the end and just run under the garage door.

This does cause a little issue, the drive is quite steep so you can imagine how fun our drive was on Monday when it was -6DegC!

So for my question! The outlet is 28mm copper pipe, is there anyway of adapting this to 32mm solvent weld waste pipe, so I can run it round the garage and through the wall into the gutter drain.

The only thing I think to do (apart from solder more copper on the pipe) is to attach 28mm barrier pipes with push fit fixings, but seems an expensive way of doing it (as would running copper for the full length).

Many Thanks,

Darren.

Could just slide the pipe intended over the copper pipe.

Hi I did think that, but thought it might be best to keep it sealed, but guess it would only be like a washing machine trap doing it that way.

Wouldn't it be better to find out why it's overflowing?!

Couldn't see a problem with it myself, no different from other drainage, just dostnt have a hopper.

Or put a water butt under it lol

And I wonder why I never venture into the open forum!
OP. whatever that pipe comes from is faulty, get it mended. If you're on a water meter it's costing you also. X

Hi, I assumed it was meant to overflow, I'm guessing not from the comments! I guess I need a plumber round then!

Thanks for the replies

Where do the 28mm copper pipe come from? Hope it isn't coming from unvented cylinder

I think it is an unvented cylinder, it's been boxed in with partition walls, I'll take the wooden slats of the top tonight so I can look properly!

Can I ask why this would be an issue please?

I'm going to step away from this and let the experts help you out, I thought it was just a one off issue and didn't want it happening again, (ie water tank over flow).
Hope its not a big problem to fix.

If it is a unvented cylinder and that pipe is a discharge pipe, the end must be sited outside as close to ground and cover with guard grille. That way, if there is something wrong with cylinder, the PRV or TRV will open, release water, sometime very hot and steam, it is discharging safety outside.

If it is running, you should get a G3 plumber to check out.

Take a photo of the cylinder

What Stardanny says, in freezing weather you may end up with a flood indoors as well.

Well, After the purchase of a SDS Drill, Diamond core drill set and plenty of 32mm solvent weld pipe, I now have a proper fix in place, still waiting on my cousin (plumber) calling round to find out why it is leaking, but thanks to everyone for all the help, feeling a lot better now that there is a "proper" fix in place (pending finding out why it is leaking!).

Regards,

Darren.

If you've attached solvent weld pipe to an unvented cylinder discharge then it's far from being a proper fix. In an overheat discharge situation your pipe will melt. It needs to be done in copper, by someone who is G3 registered

Agile · 20 Dec 2016

Unvented cylinders can explode and so the regulations about safety devices is very strict.

Only people holding the appropriate G3 qualification are allowed to work on them.

They should NOT be discharging except in a fault condition.

I am surprised your survey did not comment on that discharge.
