Water softener connection to a spigot-type washing machine trap

[woodspiral]

I'm plumbing in a water softener and I'm a bit stuck on the final part for the drain

I want to connect it to the double appliance sink trap that I have.

At the end of the water softener drain is a male 22mm thread (I think the spec is a G1017). The drain hose is around 10mm and labelled as G0743 in their diagram.

I basically need a standard female washing machine type connector on one end of a drain hose and jubilee clip around the spigot on the washing machine trap under the sink.

The problem I have is that I can't find a hose with a decent diameter with a standard 22mm female connector on - they all seem to be a bit on the narrow side. Also, looking at many sites like Screwfix and so on they don't seem to specify the diameter of the hose so it's impossible to tell. What size diameter do I need for a standard waste trap spigot? Am I looking at something specialist here or probably I'm overlooking an obvious solution!

Cheers,
Woods.

I’d use a drain pipe off a washing machine/dishwasher and add this to the end. Job done. The 22mm you state is actually 3/4 bsp female. Plastic one here if preferred.

You can put an ad on Facebook market place for a hose, someones always got a machine waiting to be scrapped.

Awesome, thanks, Shep. I knew it must be simple. I read that most plumbers don't like the spigot type connectors, but I'm willing to give it a go since it's what's there...

Next problem is to source the exact hose for the overflow - it looks like it's around 10mm thick - I think it's similar to the drain hose which I've got which the diagram says is a 'G0743'...

Screwfix do a trap with two spigots on the top, in my case I just unscrewed one and the softener adapter screws on in place of it.

make sure you check in case the inlet to the trap has a blanking plug in place !!

as phil says use a washing machine hose, but if you have a threaded outlet on the softener use a washing machine inlet hose instead as it has threaded connectors at both ends ie

Pictures of the overflow outlet?

G0743 hose here is actually 10mm dia not wall thickness so probably about 7/8mm internal diameter. if the hose is for the drain that the softener uses when it flushes out during regeneration then a new or even used washing machine inlet hose is fine (its what I used) car boots usually provide a source of hoses (i have some in the garage right now!)

Thanks chaps. All very helpful. I'm going to have a go at this in the next couple of days so will report back. I've assembled the various hoses, connector and clips.

The final problem is that I have a dishwasher that needs to be connected too. The waste will be taken care of thanks to the spare spigot from the sink waste trap, but for the supply I was thinking of using a Y connector or similar from the output of the water softener. In terms of physical shape a T connector would be better. Is that a bad idea in any way? I could plumb in a dedicated water outlet using copper pipe for the dishwasher, which will sit in an appliance recess on the other side of the sink to the water softener, but was rather hoping that a splitter connector would be good enough. This would involve possibly running an extended water hose from the dishwasher behind the sink to the connector by the softener. If there is a really good reason not to do this then I will use copper for a new outlet, but if it's perfectly do-able with a T-splitter of some kind then I'd go with that option.

Thanks for all your helpful advice. This plumbing lark is quite draining (geddit?) - I'd much prefer to be making sawdust!

Cheers,

a water softener is intended to be inserted in the water supply such that everything after the softener gets softened water. frlm your description of trying to provide a supply to the dishwasher it appears that perhaps your plumbing hasnt been altered correctly to accomodate the softener. do you have a bypass to enable you to take the softener out for service without losing supply to the rest of the house?
ie

 

[woodspiral]

Yes, I've got the bypass and non-return all plumbed in ready.

Ok. it was when you mentioned needing a supply for the d/w I assumed that there was not a feed to it from the softened side. if it was me I would put in a proper feed for the dishwasher taken from the tap supply, fairly simple with pushfit plumbing these days.
its fun working in a cupboard with limited access isnt it ??!!!!

PS if the softener is going to sit in a kitchen cupboard is the base strong enough to support the weight? I strengthened mine with timber underneath the cupboard base (just in case) a softener full of salt and water is bl**dy heavy

Another point to note.....Check the specification on your Dishwasher to ensure it is suitable for connection to an external softener.....a lot of the Siemens, Bosch and Neff Dishwashers stipulate in their instructions NOT to connect to them to a softener but to utilize the softener that is built into Dishwashers.
