Installing a Shower waste Trap

[Disciple72]

Hi all,
I've had really good advice off you pro's on here, so I'm back again looking for some more.

I'm installing a shower and am about to fit the waste trap. Obvioulsy this comes apart into about 5 pieces. I'm curious about which parts I need to seal with mastic before I jump in with both feet and get it wrong. I'd be really grateful for any advice you could give. This may sound like a dumb question but is this the only trap I need, by this I mean do I not need a seperate U-bend trap as well? Do you need to use this sort of trap on a shower or can you have one like yo have on a bath? The reason I'm asking this is because this one is a bit too plasticy for my liking I wanted something with a proper metal crome finsh.
Many thanks,

This is a pic of the trap I'm using.

The big and small white bits form the trap.

Mastic/sealant is not required.

Only personally speaking but I'd use a hefty squidge of silicone below the chrome outlet rose.....any leaks here may not be seen for a good while.
Traps like this allow you to remove gunge without any drama and another 'u' bend isn't needed.

Thanks very much for your reply. When you say below the chrome outlet rose do you mean underneath the the rubber seal that goes under it? The reason I'm asking this is because you need to be able to unscrew the outlet rose to get to the piece that comes out to remove any hair/soap build up.

Thanks one again

Often its the actual strainer centre of the rose that pulls out, allowing you to degunge etc......I would have thought that unscrewing the rose, once fitted, is just asking for leaks. Certainly its that way on the one I've just fitted!

I would have thought that as well, but it needs to be unscrewed to remove the centre strainer, as shown in the picture.

I'm thinking of abandoning this one and going for this instead. What do you think. http://www.plumbworld.co.uk/removable-top-wastes-319-0000

It is not necessary to unscrew anything to remove the strainer.

The center of the outlet lifts off to allow the strainer to be removed
for cleaning.

Yes, surely thats correct? Unscrewing the rose, once fitted, will compromise the seal on the underside of the trap too. I wouldn't want that in my house!
I think the centre bit just prises out.

Totally agree with you guys, not comfortable with this at all but the silver piece in my hand is all one piece and you can't take the strainer out without removing the whole shabang. Taking it back tomorrow and gonna go for the one in my previous post. Would you think this would be ok?

Cheers fella's

If you go with the waste in that link you will then need a seperate trap fitted.

I'd personally go for a dedicated shower waste with trap, similar to the one you have....McAlpine products are excellent but of course there are others.
This waste must be meant to be cleaned by unscrewing the large cap on the very bottom of the trap, leaving everything else alone.....how many of them are so accessible?
From what I see from your choice, you'll need to put a trap on these which is fine if there's space.

Look here on page 24

This is the type of trap you have.

Put the blunt end of a screwdriver inside and knock out the
center.

Great advice and much appreciated.

Thanks to you all

I've gone for the solid waste in the link so will have to get a seperate trap. I'm not really limited by space so what would you recommend?

Thanks

A shallow seal bottle trap.
