WHY use BOTTLE TRAPS?

[hrpuffnstuff]

@ work I have 8 basins in the girls shower rooms, 8 in the guys room (making 16 traps in all)
Then this again on 4 more floors

The refurb guys used 1 1/4 bottle traps. going into 1 1/2 then into 2"
I'm forever instruction my team to clean the traps out (espically the girls rooms cause of the hair,
And the smell is ruddy terrible, more so than i have ever come across in all my years.

I wanna know WHY use Bottle traps instead of 'P' traps
(mush less maintenance, as most of the 'crud' goes through the pipes)
YES there are cleaning eyes (2) on all floors.

I want to replace all these traps but need some evidence (from googles) as to why bottle traps should not be used, and the reasons.

Any help please?
I have googled and cant find anything useful to show the directors so as to back up my plans

cracking question. Are they anti syphone?

Bottle traps usually used where you may have to fish things out as they tend to sit in the trap. They were also used on basins as they don't syphon easily.

Get rid of the bottle traps and your bosses might be able to get rid of a man. Less work to do. I'm sure they will be up for that if you suggest it.
What is the problem with just doing the job.

I'd probably start in the girls shower room and *

Bottle traps are great as they will guarantee you further work when they have to pay you to come in and routinely unblock them. If you fit P traps you won't get any maintenance work on them.

££££ sorted!.

No, not anti syphon.

Building is 120+ yrs old so my time is better spent maintaining parts of the building that require proper maintenance

(today unblocking 2 x lead 8mtr long downpipes, that had started growing tress in them)
​

other than girls brushing their hair over the basins and putting their hair down the waste rather than the bin which is less than 1mtr away from them.:crazy:
tamz bottle traps STILL syphon back unless they are anti syphon ones (see 1st sentence)

I wondered if there was like building regs on WHY some architects recommended bottle traps?

They are good for catching pee in urinals and allow for cleaning of same. P traps float my boat every time as do McAlpine all in one traps.

yes bottles are designed to be easily accessible and allow for regular cleaning etc. P traps are better but.......the stuff will probably only build up further down the system, probably initial horizontal pipework and this can be more difficult and expensive to maintain, hence bottle traps. the trap might be smelly but not as bad as a whole pipe lined with it!!!!!!!!!!!!!
