There is usually some space around the drain hose where it goes into the drain. This usually allows enough air to get in that it is not a problem. If the washer hose is connected to the drain tight, then yes, there needs to be a vent above that connection. There may already be one above the drain if you follow it up. Most washer drains are fairly close to the main stack which allow for venting. The only question is, Does the washer drain alright? If so, don't worry about it.

How do you unfreeze a drain for a washing machine?

Raise the room temperature, or place a hot water bottle inside the machine, and allow the ice to melt in the pipes. Hopefully, the plastic pipes will take the expansion from the ice and not spring a leak.


Can you fill a washing Machine with Ice to use as a cooler for a party and if so how would you drain it after the ice melts?

Yes, you can do that. But they aren't insulated at all so plan on refilling the ice often. After the party simply run the machine as normal on "short wash". It will sense that it is already full or nearly full and will run as always. **Yes. Put it on a spin cycle if it works, lower the drain hose to ground level to drain if it does not work.


Why does your washer smell like rotten eggs when draining?

My guess is - water that is still sitting inside the inner parts starts to drain as the load is beign drained. Maybe run an empty cycle with bleach in it. Just a thought. There is a product called Smelly Washer that will take the smell out of your washing machine.


What happens if i plug a 25 amps machine to a 30 amps outlet?

Plugging a lower drain machine into a higher drain outlet is perfectly fine, the outlet will be able to deliver all that the machine needs. And the machine will only use up what it needs, so having excess at the outlet isn't going to hurt anything. The other way around, a machine pulling more than the outlet can deliver, will trip the breaker or blow the fuse.


Is sinkable a compound?

No. Unless you count the ability to funnel running water into the drain as an inclined plane, it doesn't even qualify as a simple machine.

How do you drain a washing machine into an overhead drain?

When the washing machine drains the soap suds come up through the bathroom toilet why?

The drain is getting plugged and the toilet is lower than the washing machine drain so it is easier for the water to come up in the toilet than to go straight out the drain. Put some drain cleaner down the drain where the washing machine drains and that may solve the problem.
