When down at the boat this weekend I discovered a bit of a leak. As you can see from the photos below, there are two drain valves for the domestic water system. One of them is leaking when under and pressure. The fitting is marked HEP2O 15. On removal looks like there's a washer missing, is this right? Does anyone know what I need to do to fix it? Note that the other (non-leaking valve) is of a slightly different design and has a ring washer.

Do I need a new brass tap, if so, how does it fit into the collar and seal?

Note photos upside down!

hep 2 o is the make I think and you can buy the t piece with the drain tap in about 7 qwid ,band q
 
What you have is standard Hepworth Hep2O push fit fittings, with a brass drain plug pushed into one of the tees.
The easiest solution from where you are now is to get a replacement drain fitting (screwfix have them)and another Hep2O fitting to cannibalise for the connector parts. Only problem with that is that the Hep2O fittings have been changed as they were taken over by a different company, you may find old stock on ebay or in your local diy shed.

B and Q don't seem to sell HEP2O and the Screwfix HEP2O stuff seems to be a later version. I actually think the problem is with the green bit in my second photo and I'm not sure that come with the brass hose connector or with the T piece.

Thanks, I can find Brass Drain Cocks (e.g. https://www.thecaravanwarehouse.co.uk/Products/000200050002/PF083) but I don't think that's the part that's broken. I can even find a HEP2O equal T (e.g. http://www.ebay.co.uk/itm/Hepworth-...hash=item20e24e3da4:m:m2UcEhYc9aAyDsJnN2mtvsQ) but I've no idea how to create a seal. Note that when I attach the existing fitting, the Drain cock is loose in the collar, I can easily rotate it.
 
As said HEP2o are (were) the manufacture of push fit pipe fittings. 15 refers to the pipe o/d. They all should have an o-ring seal and are suitable for plastic and copper pipe. When used with plastic pipe, pipe inserts are a must!
If you have no joy repairing the existing fitting then there is a wide range of alternatives available at any (good) DIY shop and plumbers' merchants.
 
Pete - as others have said, these are just domestic 15mm push fit plumbing fittings. Specifically where is the leak coming from? The brass drain fitting itself, or where the drain fitting goes into the t, or some other place on the t? If it's the brass fitting - replace it, they are peanuts. If it's the t fitting, then replace that, ditto. If you're not sure, replace the whole lot - ditto again. Toolstation 44521, 37798, 68773 is what you need.

What do you mean by "pipe insert"?

Anyhow, I'll spash out the 15p on a 15mm O ring (might even buy a spare)!

Thanks Jimmy, I'll buy those bits too. The job is slightly complicated by the pipes all being clipped into place and therefore rather hard to pull out from the old 'T' but I'm sure I can figure that one out.

With those nail-in clips, you can usually 'uncurl' the bit of the clip that doesn't have the nail in it and slide the pipe out. If it goes wrong and you break the clip they are only pennies to replace.

To answer your earlier question, leak is coming from here.

If the brass fitting is pushed all the way into the t and the t itself is done up tightly and it's still leaking, I'd just replace it all - total cost is only about a tenner or something.
 
As per other posts these are old hep2o fittings, there should be a black neoprene washer behind the green retaining ring, is it still in the tee piece , do not push the green retaining ring too far onto the drain cock or it will not screw fully up , suspect they have been taken apart to drain system rather than open drain cock, and left loose , reattach the black washer to the end of drain cock and tighten retaining cap then push brass drain cock fully in.

Thanks, I checked to see if there was a washer in the T but there wasn't. Dunno where that's gone.

Doh! Not to worry, I can but new old style fitting from eBay and grab rings, washers etc plus a new T as JtB suggests.
