Kitchen undersink Dishwasher connection

[psarinuk]

Hi all,

I've a Marley WTW4W Tee connector as shown in the pictures with what seems like a non-standard connector port for dishwasher drain hose.
I've tried the connectors from B&Q and Screwfix but they seem too large.

Can anyone please advise what I need to buy to connect the dishwasher drain hose to this?

Thanks.

Simpler to change the fitting probably, https://www.screwfix.com/p/mcalpine...ppliance-tee-piece-connector-white-40mm/4167P

I bought a similar one from B&Q yesterday, Not only was it longer than the current Marley Tee connector, the top section would not slide into the sink waste, so the seal could not be formed before I screwed in.

If there is no other option, I can try this one too when Screwfix opens tomorrow.

78mm height for the Marley appliance adapter, the McAlpine is similar @78.5mm so should fit ok.
