Shower waste question (1 Viewer)

[nicknoxx]

How would I go about connecting a waste like this:-

to a hose like this:

without using a trap in-between?

Thanks

With some difficulty unless you have a massive void below your shower tray. You may be better with a 90⁰ waste that your pipe will push onto and be secured with a jilubilee clip
The two waste outlets on the shower in our Adria Matrix failed recently. I had one heck of a job replacing them. Had to cut the shower tray off the walls and re-seal it. Good luck

 

[nicknoxx]

I guess I could make a suitable void as I haven't installed the shower tray yet.

Maybe not in a Boxer PVC or else you will not be able to stand up in it.

I was thinking I could make a space under the floor if necessary, rather than raise the tray height.

drop the tail of the waste through the floor and connect below probably need a series of reducers to get small enough to join to that waste i assume your using a domestic shower tray that needs 1 1/2 waste fitting
your layout youve posted previously is very similar to the layout on my self build from 12 years ago in my sig below theres a link to my blog which may help

If you don’t have a trap the smell from the waste tank can be overwhelming on occasions, are you having a tank..?

I was just about to say the same. It's going to be pretty wiffy without a trap

Yes, I fitted three of these to mine .. previous owners had just kept plugs in all the outlets. Found out why the very hot week I didn't bother with them!

There will probably be a low point in the hose which will act as a trap. If not, I'll take the advice and fit one.

Its surprising what you can learn from the forum. After a bad session of smells from the grey tank I have always thought it daft having no traps in the waste pipes.
As Ian has done a project during the winter will be to investigate fitting traps to the waste pipes.

That's a domestic sink waste. What sort of shower tray are you fitting?

Good point, I didn't notice tha lack of recess. You would need a big space below the tray to fit a trap onto that though, usually shower wastes are quite shallow with integrated traps and side exit fittings.

To me it looks like a domestic sink slotted waste. The slotted is used for built in overflow, in the ceramic sinks. This would be wrong for a shower tray, unless the outlet is so deep that covers the slot.
Shower tray waste is much larger at the top.

You can get adapters for washing machine and dishwashers that usually go under sink with 1 1/2 tread to a 22mm spigot. Make sure you use a un slotted waste. The one in the picture is slotted, and will leak out.

You would be right, but that isn't a slot in the picture, it's the side of the nut that's caught the light.

I was thinking I could make a space under the floor if necessary, rather than raise the tray height.

There are 2 trains if thought on this issue, if you make a space between the showertray and the floor if the van and something breaks or gets blocked in the future then you may have to rip you shower tray out to fix, and whilst using shower, you may get water backing up or filling tray because of sheer volume of water. If, on the other hand you consider having the waste pipe dropping vertically down through flooring to underside of van, and have trap fitted then it’s a much easier job to work on any blockages and the water runs straight down through the floors keeping the tray emptier. Either way it’s worth speaking to Magnum Motorhomes for any bits.

Also it’s worth putting too plug holes in so it empties whether you are level or not.

There doesn't appear to be room for an angled waste.

 

[bigwood]

From watching the videos of self builds I think most people put the shower tray on battens to give room underneath for the waste pipe.
I will be fitting the traps to our motorhome underneath the floor before the pipe goes into the tank.

Motorhomes don't have waste traps.

I had to fit a very similar replacement shower fitting in my old Coach-built. Too tight within the floor for the stupid thin pipes the original build used so went right through floor to underside and built a small enclosure to protect an ordinary u bend.

 

[The Wino]

Motorhomes don't have waste traps.

I'm pretty sure ours does built into the fitting under the sink

This is the waste on ours we have a chausson MH but got a waste like this when the original broke

They're not a trap as such, they have a slightly deeper flat bottom to hopefully catch any none fluid waste - food, hair etc. They don't stop any odours returning from the holding tank or the pipes as they don't fill with water as this water would begin to smell too.
The Hymer basket type is better than the plug type for showers. The small basket is easily removable.
