How to plumb in a sink in a garden shed.

[abrogard]

It's a twin tub sink and we're putting cold water on only. Unless a really cheap online hot water thing comes onto the market.

The thing is I've found the two tub thing for under the sink that joins the two tubs into one outlet.

Now I figure I simply need something to screw into that, turn 90 degrees and exit through the shed tin wall.

The grey water will just spill out into a trough and be used for garden water.

So I don't need any P traps or fancy stuff.

But I don't find anything that is simply a 90 degree bend. Do I have to make it up for myself from a couple of pieces of 2" pvc and an elbow? But it looks onl the picture like the bottom of the 'two tub' adapter thing has a kind of screw fitting.

What's the reality?

And while I'm here how about the two semicircular washers on the bottom of the two tub tap we've got? They go one on top of the sink and one below? Or both at the same side?

All looks a very frail method of fastening to me - just that one about 1/4" threaded rod. That's how it's done?

Flat rubber seal goes on the bottom and the only leak proof connection is an adjustable S trap that screws onto the bottom of the twin bowl joiner, just turn the last leg of the S trap to 90deg, cut and fit short piece 50mm pvc pipe out through wall to trough. You will be glad of the trap, it will keep insects and crawly types out of the sink.

flat rubber seal. of the two on the tap? bottom one on the bottom under the sink? good.

I can't find a simple 'S'. perhaps they don' sell them in Aus.

You've done such a mighty job it makes me feel bad about asking more....

but the P trap - I have to get straight pipe of some sort that screws into that? It seems to have a threaded end there...

And i don't follow the 'plug and waste reducer' ? I get the idea that it's either the P trap or it, is that it? Not the both of them? It looks like a thing for screwing right into the sink, too, where our sink already has something there fitted in, with a downward leg of about 100mm or 4 ".

Funny that, too. Both sinks have this fitting but one of them, the main one, has a threaded rod running down in there too, somehow. Don't remember now. ( the shed's in another place entirely, not where I am now ). Wonder what that's about...

I agree about using a P or S trap , we had small frogs crawling back up into the sink and depending on what I put down there it sometimes stank.

The threaded end has a rubber flange inside and you slip the straight pipe into it and then screw the threaded end to squash the rubber flange onto the pipe to seal it

Here you go, just happen to have one sitting here.

Aha. All solved.

Thanks very much all concerned.

So I'll get the double bowl connector and the 50mm P and a length of straight pipe to put in the end.

And I'll fasten the tap down on the sink with one washer on top and one underneath.

And a garden hose running into the adapter nut on it.

And we'll be done.

Water in the shed.

p.s. thanks DJ, just saw your latest post with the pics. They put me in the picture alright.

garden hose will def give you water in the shed but not the way you think. Garden hose is likely to burst if left under pressure the entire time. Ok if you turn the feeder tap on and off when you leave and enter but there is a reason they don’t use garden hose when building houses🤭

[abrogard]

I know what you mean. I've had some little experience with them. We'll do it just to the get the thing up and running. Then I'll improve it. I guess that white pvc stuff is the way to go - bury it in the ground? About 30 metres or more and concrete to navigate through.

That's going to be my next question: what fittings required each end of the pvc when it has a garden tap at one end and a sink tap at the other?

And I guess I might have to take the tap off and put a T piece under it so's the T can feed the shed sink.

Sometimes the world seems to be nothing but plumbing.

Use the blue line poly pipe and irrigation fittings, it is permanent and will withstand mains pressure in all conditions. All the fittings and pipe are available at Bunnings. It doesn’t get any easier than that.

[abrogard]

Well that sounds pretty great to me. No 'ifs' and 'buts' - just blue line irrigation will do the job.

And fittings are available for each end of it to connect to the two different taps - or the T piece at one end if I put that in?

There's garden hose and then there is GARDEN HOSE.

Because I had heaps of white 20mm retic pipe under the house so I decided to use it to supply water to my shed. It's hard plumbed ~25m away, underground from the tap in the shed to a riser next to a rarely used garden tap on the side of the house . Between the riser and the garden tap initially I used a 500mm length of quality garden hose. I did this in case I ever wanted to use the tap. It was this way for ~10 years - zero leaks. I should add the short length of hose and garden tap are in the shade

I have since added a twin diverter to the garden tap and connected the riser to the tap using a length of braided hose such as it used to connect up basins inside houses.

As long as your hose connection is outside where it won't flood if it leaks you should be OK. I usually turn the garden tap off if we're going away for more than a couple of days.

There's also a horse blanket washing machine on the side of the shed, the waste water of which goes onto the lawn. This machine was initially set up to temporarily get its water via the garden hose on a reel on the back of the house. This hose just lay on the brick to the tap about 15m away bit was a bit of a PITA setting it up every time I wanted to use teh machine. While doing a bit of a clean up under the house I found enough bits of old cheap garden hose to set up more permanent connection so that it ran out of the way behind potplants on the side of the paved area. The water in the hose was normally turned off when not in use and used this setup for about a year, sometimes forgetting to turn the water for a couple of days, before the hose started to leak from a section of hose that was constantly exposed to the sunlight. I replaced the hose with a new mid range hose and even though parts are still exposed to the sun, about 4 years later have not had any problems although I do not usually leave the water on.

I wouldn't do this for any water supplies inside even a shed.
