External grey double waste connector

I've just googled lunar spare parts and there are a number search results, I assume you have tried that approach?

I'm not sure which double connector you mean. My 2003(?) Lunar used to have 3 hinge covered outlets  at the back until I used a Y connector underneath to put 2 into 1 outlet. I then used domestic waste fittings to put those 2 into 1 and into the Wastemaster.

I got a 'Y' shaped connector and 3 pieces of corrugated plastic pipe which then fitted into the twin outlets  with one pipe going into the waste barrel.

Got them from my local caravan dealer.

Duplicate post.

Stupid forum software

This article tells you how to make your own, either with the corrugated grey flexible hose into the outlets or use the 28mm said pipe:

I’m surprised your local Caravan dealer doesn’t have any. There’s a few to choose from HERE

Our Lunar's three outlets are all together so we made one of these.

Try that one.

Are you sure that they are double and not just two single outlets side by side?

 Many thanks to all. Yea deffo twin, have got some great info. Thanks to all responces, Mal.
