Y connect washer and dryer???

[bedtester]

Is something like this ok to connect washer and condensing dryer to the same drain spiget. I was planning to fit a double stand pipe but room behind integrated appliances is proving challenging. Plan B is to run 2 waste pipes to the spigets under the sink. Dishwasher, Washer, dryer in that order

My concern is the washer may pump drain water into the dryer

Fit one of these on the top of the Standpipe. https://mcalpineplumbing.com/traps/domestic-appliance-traps-accessories/twin-connector/

There's literally no room to squeeze a stand pipe behind the appliances, believe me I've tried. The waste hoses for the dishwasher and washer will fit and reach the sink trap spigets if I run them down the skirting recess behind the machines. The dryer hose is much to short but could tee into the adjacent washer hose. Just a little concerned the washer will back fill the dryer with drain water‍

Syphoning only occurs if the hose route is not correct, connection for all must enter from a higher position than outlet.

I've found this product to add a 3rd spiet under the sink. I'd have to extend the dryer hose to reach it.

Not a good idea to share a drain hose, it is designed to pump one appliance at a time. Could it backflow, probably not but there would always be a risk.

What size of hose is on the drier, usually they're a lot smaller than standard drain hoses. Why not just extend it?
