Dishwasher and washing machine into one waste spigot

[sonray ltd]

Give use a pic the jon of your new drain connection.

 

[Jon Parker]

Just had to nip it up by half a turn on each screw as there were a few drips on emptying the sink after tonights washing up, but refilled, re-emptied and now dry as a bone.

 

[Jon Parker]

The kit also comes with a 90-degree elbow but this is optional and I don't need it.

 

[sonray ltd]

Stick a jubilee on that stigot just on the safe side.
Otherwise jobs a gooden.

 

[Jon Parker]

Yes, curses! I forgot to buy the jubilee clips today. I even stared right at a whole rack of them for several minutes whilst waiting for service in one place! Bah! Silly me!

 

[sonray ltd]

That's sods law.

Also keep hold of the cutter you'll never know when you might want it if you ever move the drain connection or fit a new trap etc.

 

[Jon Parker]

Yep. Already filed away in my "might use at some point in later life, but probably not" section of the shed, along with every off cut of every piece of wood I've ever purchased and not used!

 

[Jon Parker]

The smaller y-piece arrived today, excellent delivery speed from Welcome - Stevenson Plumbing and Electrical Supplies. It's now all connected up and working fine.



Once again folks, thanks for your assistance. Saved me a pretty penny I'm sure.

Regards
Jon

Thanks for completing the thread with a happy ending Jon!

Bah! Spoke too soon! After the dishwashers 2nd run I've got water in the cupboard. Seems to be coming from the underside of the drain cut-in clamp.

I re-read the instructions to make sure I've done it properly, which I have. It says suitable for 40mm and 32mm pipe, I have 40mm - which means you must remove the 2 spacers before fastening the clamp tight, which I have done. Can you see though how where the clamp goes over the pipe it's nipped quite severely? Is this normal for such kits?



It almost looks like the clamp is too small for the pipe and as a result the pipe is being squeezed, deforming as it does so.

At first I thought it might be water leaking from where the dishwasher drain hose goes onto the spigot (still no jubilee clip) but I had a good feel around and that connection was dry as a bone. Definitely seems to be coming from the clamp somewhere.

Shall I risk another half turn on each screw? Is the pipe likely to shatter or just bend if it's over stressed?

 

[Mike Jackson]

Read the instructions again. Looks like you should have left the spacers in for 40mm.

 

[Jon Parker]

It says "Position the 2 plastic saddles over 40mm waste pipe. For 32mm pipe leave the 2 spacers in place."

Did you tighten it up like the Incredible Hulk!? Looks over tightened to me!

 

[SafeGasInstall]

Cheers for that, I have looked. What is the name of what I'm looking for? "Spigot Y-adapter" and variations is not coming up trumps.

NEVER USE them !!! have been called to two flats that had one of them Y , and they both flooded the flats below

I agree it does look over tight but the clamp will only tighten so far. It's not quite fully closed either. I don't have a big enough screwdriver to tighten it anymore. The pipe is definitely nipped.

Thanks, but I've gone with the self-cut extra drain spigot as detailed earlier in the thread.

 

[Jon Parker]

Just checked the screws. Yesterday I tightened them all up pretty much as far as I was physically able to. Today, the two screws at the front I was easily able to put another full turn. It feels like they have slacked off. This is all going very strange, and I may just plump for the Mcalpine SK1a trap and do the whole lot.

From the pictures, have I got push-fit, compression or solvent weld piping?

 

[Rover]

stick a bit of silicone round the edges

 

[Jon Parker]

Silicone on, will see if that has any effect. Thanks for the suggestion.

 

[sonray ltd]

Bloody hell jon you've over tightened it slightly.
You don't need to tighten it so both clamps meet, The top clamp has a o ring that seals it when just hand tight.

Any mileage in slackening it off? Will the pipe regain its shape or stay deformed?

 

[sonray ltd]

That won't regain it's shape.

 

[Jon Parker]

I'll leave it alone then, and hope the sealant does the business!

 

[sonray ltd]

Shame really all was going well.

 

[Jon Parker]

Agreed. Instructions didn't say anything. I assumed tight=good.
