Saw this today for the first time. Apparently we have been selling them for ages! 🙂 I had never seen it before.

Its a cross between a self-cutting tap and a DOC. The idea is that it is a temporary fix to allow you to drain down when there are no DOCs fitted - once drained you take it out, replace the bit of pipe that you have cut into, and fit a proper DOC so that the next plumber doesn't have the same problem.

Clever idea, or just another gadget that will haunt the van?

why now order from ray our forum sponsor ?

what you knocking them out at ray plus pnp ?

At the moment BOD, we aren't really geared up for mail order. We are working on that at the moment, so in the relatively near future we will have an online ecommerce site.

As a bit of fun though, I will post out 5 to Bod, Buckley Plumb and the next 3 Plumbers Arms members that PM me a snail mail address. No cost, just come back on the forum and give a short bit of feedback. (Can be positive or negative).

The bloke who invented them (and a hundred other little plumbing gadgets) is an old mate of mine, and I saw him today, so am really doing this as a favour to him.

If you want one, and live in the South East, come into your nearest Williams and get one. If you are out of our area, show the pic to your local independent merchant and tell him they come from Pond Agencies.
 
they are a very good way of draining down when there are no docs, i have one with washing machine 3/4 fitting on so i can attach a drain hose with no leaks unlike sometimes with a doc.
 
Thanks Ray,
Is there a 22mm version made as well ?

I don't know. I have emailed my mate a link to this thread, so hopefully he can answer. Maybe a new product idea for him.

He does do a 22mm wide aperture type A DOC, which he reckons allow you to drain down 77% faster than using a 15mm. Its the same principle as a normal DOC, just a bigger body, a decent gland and plenty of room for the water to flow, or the odd bit of debris to pass. Combine that with a self-cutting head, and you wouldnt have time for a cuppa whilst the system drained!

now that sounds a good idea.
 
These are very useful in emergencies, more so as burst pipe season is nearly upon us. If you get a call out in the wee small hours to cap a water main but can't get the water switched off, fit one of these before the burst, connect a hose to it and divert the water outside, it takes the main flow of pressure off the burst pipe, making it easier to fix the burst.
 
could have done with one of those today,40 year old system,knackerd pump and fitted by a monkey,no isos on it and no drain offs what a PITA had to disconnect a rad to drop the system only to find they were mini era valves and not 3/4 tails ,and neutral point was blocked the joys of old systems,oh and after sorting all that the gravity circ airlocked
