Help with bath waste

[GaryMo]

The outlet for the shallow trap I have for the bath waste is in line with the bath leg brackets. Is there something available to drop the trap lower or even a trap that has a lower outlet compared to the inlet?

I've attached a picture just in case the above makes little sense!

I cant realy tell from your picture but you could swivel the trap 90*s and use waste fittings to run the pipe work where ever needed

You can use any 40mm trap, but you may have to cut a hole in the floor to accomodate a deeper trap. If the waste is going to stack then deeper traps should be used IIRC.

Alternative may be a HepVo valve: http://www.plumbworld.co.uk/hepv0-self-sealing-waste-442-1788

Just get a low level bath trap from plumb centre

Use them all the time on the bath you have in that photo.

Thanks all.

I've gone for this option. Is it OK?

 

[dextrous]

yep, although make sure you hoover the carpet before you put the bath panel on

 

[GaryMo]

Lol, it's currently in the middle of our bedroom!

Correct. That original trap looks like it only has a 38mm depth trap seal, only a trap with a 75mm trap seal can go straight into a soil stack. The second trap looks to have a 50mm trap seal but cant tell from here. the 38mm and 50mm traps are OK if going into a hopper.

 

[GaryMo]

Where do you take measurements? Bottom of outlet to top of bend?

 

[neds]

The depth of seal is from the top of that bend to the bottom of the discharge as indicated...

Well Said and Thankyou ,Neds.... Looks like a Hep V O with a 90 degree adapter would just clear the metal bar PS do you know why the Tower of Babel was never finished........ Because the bloody gas fitters got involved Giving rise to the expression ARGI - Bargi

Sorry to correct you but you are mistaken there.

50mm seal on bath trap is required, not 75mm.

Hmm was always taught for anything less than 50mm pipe requires a min 75mm trap seal, I supopse that link is very reputable so...

Depth of trap seal is more to do with soil/vent pipe arrangement - the Single Stack is pretty much universal now and required a 3" seal when it was introduced . It`s very likelyB`stard ised much over the years,in practice.and that`s why I recommend the hep valves ...
