Washing machine drain connector

[gmc600]

Looking for some advice, I've got a washing machine that drains under the sink via something like this:

https://www.screwfix.com/p/mcalpine-v33s-compression-domestic-appliance-tee-piece-connector-white-40mm/4167P?tc=CA8&gad_source=4&gad_campaignid=22609680925&gclid=Cj0KCQjwjo7DBhCrARIsACWauSkw8Obin5CWi9m_fmj7J-eQmb5r85cku8hfKcQyuHxHpjBpexhILo4aAiRgEALw_wcB&gclsrc=aw.ds#product_additional_details_container

I've now got a dryer that also requires a drain, is there a connector available that allows both to be connected at the same time?

Thanks

Seems like DIYnot has disabled the link, if you copy and paste it it still works, or search for "McAlpine V33S Compression Domestic Appliance Tee Piece Connector White 40mm (4167P)"

I am not a plumber, but would the following work?

McAlpine WM11 Washing Machine Trap

Includes two MA15 nozzles.

Edit- you can get a double connection that goes onto the existing spigot, but I believe that the appliance manufacturers insist on an air gap between the two waste outlets. The following does NOT have that.

Sorry, first post not entirely accurate, here’s what’s under the sink right now.

Pipe splitting off on the left is washing machine drain, one on the right appears to be coming from our boiler as far as I can tell

Looks like you've got Boiler condensate and washing machine already connected, changing the trap isn't going to be straightforward, so you may need to look at cutting another Tee in somewhere.

Then, either connect the Condensate to that, (will need a Gas Engineer to alter the Condensate pipework), and then change the Trap for one with two appliance connections, or run suitable pipework from the existing waste to accept the new dryer connection.

Hello Gmc600,

This might be worth a punt:

It might fit where your washing machine is connected and is less than £7. It also means you don't have to touch the boiler condensate pipe.

I did link to that, but also mentioned that I have read that there needs an air gap, which the one in your/my link doesn't have.

Air gap is provided within the trap, as long as the discharge point is above the water level in the trap.

Thanks. I (incorrectly) assumed that there needed to be an air gap between the two waste pipes.

Thanks all, I'm intrigued by the presence of the air gap, is there ever a scenario where you put a lot of liquid down the sink or from the attached appliances and it's enough to fill the pipe completely and leak from the air gap?

In your scenario, the air gap is within the confines of the trap, (just ensure if fitting the Y adaptor as linked, that it is horizontal, and both connections are at the same height), as the water will discharge above the level of the water in the trap, the plughole is open to atmosphere, and should the plug be in, then the overflow will provided the required ventilation.

Both drain hoses also need to be installed as per manufacturers instructions and rise from the appliances, to the underside of the worktop, before dropping down to the discharge point.

Anti Vac traps can, if the outgoing waste pipe becomes blocked, back up and leak from the air admittance valve, but that is a pretty rare occurrence as most would deal with a blocked waste before it becomes that much of an issue.

Sorry, didn't notice you'd already linked the same product from a different seller.

No probs. You posting it helped @Hugh Jaleak correct my mistaken understanding of air gaps.
