What's the consensus on using this for the plaggy joints?! I'm sure we've all done it before. Picked up some silicone spray today cheap enough.

Yes plastic I meant. I've heard that fairy rots the rubber seals

we have used loads of different things,special gel lubricants and sprays but I cannot see how fairy would rot the seals
we have been back on a job this week from 2002 adding new drainage and the old stuff is still working fine
but I cannot remember if it was fairy or not :;):

Horses for courses. You should always use the right lubricant for pipes as it also protects the rubber from ground salts etc: Wash up liguid
Contains salt that can rot the rubber over time. In big pipe lines we use putty and denso around each joint to protect from contamination.

Sean's right - much better to use the proper lube, particularly when there are rubber/nitrile collars involved.
Some wash-up liquids, when neat, are a bit too aggressive. Obviously, pipes and collars need to be able to withstand them in dilute form when they're being sloshed down the sewers, but the good quality wash-up liquids, undiluted, are a bit much.
Having said all that, I've never understood why pipe lube, which is essentially a crap soap, is so expensive. Makes no sense!

well 14 years on the current pipework is still in good order! also as said multiple stuff tipped down drains every day
I prefer the spray over the gel ,but if neither are available then out comes the fairy

It will "still work fine", after all the pipes are in tight against the register making it a tight seal. You wouldn't use pipe lube to wash the dishes :;):
We have in the past discussed wash up liquid and the damage it does to compo'. I just think that as professionals we should be recommending the correct materials along with compliance. As the gaffer says: I to can't see why the lube/grease etc: is so expensive. Woe betide my top man who leaves the lid off the tub of grease

Yeh never use it in compo any more. Too much efflorescence and the concentrated plasticisers seem to last ages anyway.
3 quid for 200ml spray. Not too much more than fairy

I agree wholeheartedly Sean, but as said the top gets left of the tub or the silicon spray gets snaffled for barrows or something else
havent used it in muck for 10 years the sachets are where its at now

I would have thought acid and other toxic stuff what goes down the drains are more harmful to a rubber seal than washing up liquid ?

As above Mick.
