Shallow Bath Clearance - Which Waste?

[Jay666]

Hi, I'm plumbing in a cast iron bath; however, the clearance between the bottom of the bath plughole and the floor is only 64mm. What, if any, is the most suitable waste to use (u-bend or bottle trap or other)?

FYI, it's a tiled bathroom floor and waste goes into the soil stack.

Advice from you experts appreciated!
Thanks, Jay

you will probably have to angle it to the side of the bath as the outlet is a wee bit higher than the threaded bit if you see what i mean

Thanks chaps -

Nige F - you mean one of these? http://www.onplumb.com/40mm-hepvo-self-sealing-waste-valve-cv1.html

Bingobongo - yes, the outlet end will be too high to fit under the bath so I'll have to rotate it so it's level with threaded bit. Is there a chance that rotating will compromise the purpose of the u-bend bit though? Also, looking at the image, it isn't clear which bit will need to rotate? Final q - do you know what the total height of the fixture is? I couldn't find dimensions on the screwfix page. Thx

If you are discharging into a soil stack, its against regs to use one of these as the trap depth is insufficient. They are only to be used when discharging into a gully or hopper (see Screwfix description).
