Brew area sink plumbing query

[HoppyTommy]

Hi

I've managed to acquire an old Belfast sink for my garage to add to my brewing area. I have water and power in the garage but no waste water.

I only brew about once a month so I was planning on running a 4m length of 32mm flexible hose from the sink waste out of my garage door to the nearest waste water drain on the back of the house. When not in use I would coil up the flexible pipe and leave it hanging on the garage wall. I'm planning on putting an isolater on the pipe to the tap above the sink in case anyone accidentally turns it on when the waste is not in place.

I've come to order my plumbing bits tonight and I've hit a bit of a snag. Are there any plumbers (or good DIY'ers) who can recommend the correct fittings to go from my sink waste to the 32mm corrugated pipe. The sink fitting is a 40mm threaded male part. My best guess was a 40mm to 32mm adapter that would allow me to insert the 32mm pipe into the compression fitting with a good smear of sealant and hope for the best. I'm not fussed about a u-bend or trap.

Has any one got any bright ideas or other suggestions to solve the problem? It would be so nice to have a sink near my brewing area. Photos to follow. Thanks in advance.

Hi!
I think the 40mm thread on the sink outlet is designed to take a trap.
Install a trap and then a reducer and a short length of 32mm waste pipe. If you put the corrugated hose in very hot water it may push over the 32mm waste pipe, especially if you chamfer the waste pipe; you could seal it with a Jubilee clip.

Thanks for the reply. That sounds like a plan. I've ordered a few bits and bobs and I'll see what goes together. Cheers

Had a play with my plumbing stuff tonight and you're spot on BigCol. A bit of hot water and a bit of sanding to my 32mm pipe and the corrugated pipe went on a treat. Got a cheap trap for about 3 quid. Starting building my brewing bench as well. Picture a Belfast sink on the right hand side.

All up and running. Waste pipework works a treat, cheers for the advice BigCol Did my first brew on Wednesday. Lovely not to be messing round on the garage floor.
