OK. I know that I am taking a wee liberty... Pardon the pun! 
BUT....
in as much that I profer my advice in this forum to DIY-ers I am bemused with regard to work undertaken by outside contractors for an organisation that I carry out 10-20 hrs per week as a general handyman and I would welcome your comments on a particular issue.
Approximately 15 months ago... the outside contractors that usually carry out and double check the dhw outlet temps (max 60 degs) and stored cold water (non potable) annually clean and sterilise the cwst's, empty the sani towel bins and issue health and safety certification ertc etc... were appointed to water saver time switches that serve 3 sets of urinels 15 in total. They also replaced the tub swiv p traps wi 40mm bottle traps and put tablet deodouriser cleaner plugs in the top of the urinal waste outlets.
Now, every 3 months or so the urinals discharge rate is so poor that MUGGINS (me) has to mask/vicks synex smeared mask and glove up to....??? dismantle the bottle trap access to wire brush out all of the crystallised ureic acid and cleaner residue coz the water is spilling over the lip of the urinals
Consequently, the o ring has memory loss and now every time the timer flushes thru... water drips out of the bottom of the trap!
Now... I'm all for energy efficiency, reducing unecessary use of water and recycling....(especially copper and brass!) But... n here's the rub...
Surely the restricted channell(s) available in bottle traps over p traps combined with time/flush switches and the inevitable gunge from the soluble tablet dispensors leads to an inevitable accumulation of foul gunk! n mugins 'ere avin' to brush out the traps n rod the discharge pipes (40mm to 50mm to the soil)
Q? I mentioned this to the chappy at my local plumb merchants when I purchased 15 x 40mm tub swiv p's... and he concurred "I have also wondered why they fit bottle traps to urinals"
Funny what you notice and think about when you point percy at the porcelain...innit!
