Waste tank connection

Hello all.

First post here, I've registered as the forum seemed full of knowledge which hopefully a few may share with me!

Wondered if anyone can help me with a solution to the following.

I have a plastic under vehicle waste tank fitted to the van which was converted by previous owner.

Two waste pipe connect in a Y piece under the chassis then into the waste tank.

To improve drainage from the sink and stop the gurgling shower tray I want to route both wastes separately to the waste tank with possibly larger diameter pipe.

This means I need to add a waste pipe connection to the waste tank.

I haven't yet been able to (and would prefer not to) drop the waste tank off the chassis to see if there is a top access opening for tightening a new tank connector.

Has anyone any experience in fitting a new connector externally without inside access? I was thinking maybe a some sort of tank flange siliconed and pop riveted? Water will never be under pressure or submerged in water and absolute worst case is a drip directly onto the floor.

Or perhaps it's a tank off job.

Will try and add a picture of the sort of thing I was thinking.

Maybe one of you can make sense of all that!

The place to get tanks and tank fittings for MHs is CAK Tanks and they may supply those special flange attachment fittings which can be fitted entirely from the outside.

I suggest that it would be preferable to use the illustrated stainless steel self tapping screws, rather than the suggested pop rivets. The mandrels of the pop rivets could come loose, or corrode.

I too have found Caktanks excellent esp for plumbing and gas stuff. I bought a better water contents gauge from them in Oct and have been meaning to fit it but found the thought of dropping the tank for access somewhat daunting.

A couple of weeks ago I plucked up courage and drove my M/H up the levelling ramps which gave, even a "fuller figure" like mine, enough room for access.

Drained the tank and using some bricks and a jack it dropped out dead easy, just four 15mm bolts. So don't be wary of taking out the tank, it really isn't as hard as you think.

Any idea what size the final waste pipe pipe is on an Autoquest as mine appears to go up and over the leaf spring so the bottom 40/50mm doesn't empty unless the MH is leaning the right way. Looking at extending it around the obstruction????
I can't measure it at the moment!!
