Simple hose connection?
 
4 Attachment(s)
Just bought a new washing machine and have a problem connecting it to the utility sink it drains into. Here's the sink:
Attachment 18896

In the side of the cabinet there's a plastic inlet pipe (not visible in the photo above - it's on the other side) that connects to an outlet in the sink, below the faucet -- that's where the drainwater comes out. The washer drain hose should connect to the pipe that goes into the cabinet.

Both the pipe into the cabinet and the washer drain hose are 1" diameter rigid plastic. The old washer drain hose was perfectly round, and I used a piece of flexible rubber hose to connect them:

Not pretty but it worked fine.

The new washer drain hose is NOT perfectly round - it has three small grooves. Here it is from the end and side:

The old connection method won't work now. Because of those grooves, a little water leaks out no matter how much I tighten the clamps.

This new drain hose seems to be washer-specific. The way it connects to the washer, I can't use the old hose in the new washer. I looked at "universal" washer drain hoses and they don't look like they'd connect to that washer properly either. It appears I'm stuck with the current one.

Is there any easy way of making a leak-proof connection, given those grooves in the drain hose?

The alternative is to hang the drain hose over the edge of the sink, and of course that works fine but doesn't look as nice.

Thanks for any help.

Ayuh,.. You could probably use a hose barb for an internal connection, instead of external...

The grooves inside are ridges
 
It's hard to see from the photo, but the inside of the drain hose isn't round either. Those grooves aren't just external -- the whole hose end, inside and out, is molded in that shape.

Would a hose barb would make a tight seal with those ridges pressing against it?

Ayuh,... Can't guarantee it, but the hose clamps will be compressing it Flat...
Rather than the way you have it, with the clamps compressing it, inverted...

You might want to go with a Brass barb, instead of plastic...

youre scaring me here! :laughing: if its the drain from washer your trying to route,dump it right into the sink not the drain. :whistling2:

Suggestion that might help the idea of an internal barb fitting making a tight fit...

Boil some water and place the end of the hose in the boiling water. That should soften the pipe to better conform to the barb without risking melting the plastic.

On the barb, you can make it slide on just a little easier if you coat it with "standard" KY gelly (water soluable and won't harm the plastic).

While the hose is still hot, try to force it over the barb and then use a hose clamp to hold it tight.

The drain hose is indeed from a washer. Either way the water goes into the sink. The pipe built into the below-sink cabinet enters the side and routes to an outlet at the top of the sink, right below the faucets. The water comes out there and goes into the sink, then down the sink drain. It's designed for that purpose. It just looks neater than having a hose hung over the side of the sink.

Thanks, all good suggestions.
