I've fitted god knows how many trays over the years, when I've not used any sealant ive had the occasional leak, when i have used it ive never had a leak. Plumbers gold, ob1 etc are best, just a small bead does the trick. Each their own
Thanks for watching Jason. Yes new methods cant be ignored. I had a DIY friend recently fit a shower tray onto 18mm marine ply using just silicone. Non of this 25mm of sand and cement bedding business. Now idea how long it will last obviously...ATB b33zo
Hiya, great video and very well explained. There is a small pipe feeding out of the outlet, what width is that? And the connector after that, what width is that? And the third pipe too ! what width is that one ? This would help with my shopping list as I am going to order one of these.
Thanks for watching Eamon. The shower trap which you can get from your local plumbers shop or Screwfix (item 45503) takes a 40mm pipe. Pick up a few 135 degree bends and some solvent adhesive while you're there. Good luck. b33zo
@ Thanks a million for this. I looked at the 135 degree bends and will pick up a couple for sure. I already had the shower trap for install hence my query. Thanks again, Eamon
Lol. That’s the trouble with TH-cam isn’t it? If you’re a DIY’er you can get confused and wonder which way is best. Truth is there is more than one way to do this job. Nothing wrong a bit of plumbers gold sealant for added reassurance but it isn’t always necessary. A good quality rubber washer will seal it if it’s all clean and assembled correctly. Much easier to replace to when the time comes although not too difficult even when sealed with the help of some rubber gloves.
Thanks for watching@@tellylgeorge . Very true sir. If you have a decent shower tray and MacAlpine fittings the rubber seals should make a perfectly good leak-proof joint. b33zo
Agree. Some say use Silicone (like in this video), some say don't use Silicone and use Plumber's Putty intead. Some show a black O-Ring with a cardboard ring warning you not to tighten without or the ring will warm and of course mine does not come with one. My late dad had a saying.. Ignorance is Bliss. The more you know the more you'll get confused the more you worry you might not have done it right.
Nice video. The waste (the part you screw in from the top) on mine is disintegrating, maybe the UV light is causing it. I can't access the trap under the floor but my plan is to only replace the waste at the top. If I take the existing waste off (probably use Dremel so the trap is not forced), can I screw in a new waste without needing to hold the trap from below? I noticed you managed to tighten the waste from the top without holding trap.
Thanks for watching. I recently had a similar job but luckily a considerate carpenter had created a small 'trap door' in the floor and I could access the plastic trap to change it. I believe I saw a video where the plumber had wedged something into the bottle part to hold it up in position while he changed over the top screw in part. Definitely worth a try before ripping up the floor tiles. Good luck. b33zo
Thanks for watching. A lot depends on the access available the number of corners and bends and the likelyhood of leaks. I would solvent weld where possible as its a permanent joint. The shower trap has a compression joint connecting to the pipework so that it can be replaced if necessary. Just remember to leave a 'manhole' in the floor for access. Good luck b33zo
My waste has only one rubber seal that fits under the shower tray. There is none over the shower tray opening which as this video shows fits underneath the screw top. I noticed this when last cleaning out my waste. Also no silicone has been used. Is it normal for just one rubber seal to be present or is one potentially missing from the install?
Thanks for watching Dando. The McAlpine waste system comes with everything you require. It sounds like the upper washer may have been left out. Main point is: does it leak? If it doesn't leak and you have limited DIY experience of spending half a day on your knees I would probably leave it alone until it does. Best wishes b33zo
My new shower tray came with a mcalpine trap. Only one washer supplied for underneath and install leaflet says to use a "neutral" silicone sealer for top of the tray. It's the old style of tray, not the slimline type. Hope this info helps.
Thanks for watching shailen. I haven't seen any hair traps for this sort of fitting. For cleaning it's very simple to remove the shiny cover together with the tube and cup to totally clear any hair etc that might have entered the trap. ATB b33zo
Agreed Brian. What McAlpine recommend and what I do is based on DIY experience and failures. Out of interest can you name of a plumbing job where Plumbers Gold is recommend - I've never used it before this little job? b33zo
Apart from making it more difficult to remove the trap in the future, what's the harm in using something like Plumber's Gold? I ask because I am doing a shower trap replacement job (this stuff is all new to me, no experience at all) and in removing the old one, there are a few scratches on the shower tray, so I'm thinking a seal is a good idea in my case. Always like to hear the argument against though...
Thanks for watching rh. I think if you watch again you'll see quite clearly that the protective film was peeled back for fitting the tray and is removed from around the waste before fitting that but left on the main part of the tray for well, protection. Good luck with your project. b33zo

Do you need a separate trap to prevent sewer gasses with this type of waste?
@dhewitt2514 thanks for watching. This waste forms a trap once it contains water. No other parts required. b33zo

Hi there, any recommended hair trap to use with this waste trap?

Will that shower trap stop smells coming back if connected to soil?
Thanks for watching Tiger Eye: Definitely. b33zo
You'd want one with a no return valve. Like the McAlpine
ST90CP10-NRV 90mm Shower Trap with Non-Return Valve
Can CT1 be used instead of plumber
Gold?
i would have thought BT1?
Shower trap
No need to put any kind of sealer on these McAlpine shower traps ,indeed McAlpine recommend that no sealer should be used on this product.
