Washing mach- remove sewer cap?

[ferg00]

Whats this mean? Does everyone do this?

It's my understanding that some RV's are plumbed so the washer doesn't drain into the gray tank but, rather, into the drain line after the tank. This means that you must remove the sewer cap so water can flow away.

The tank could overflow and back up into the RV.

The two I’ve had are plumbed directly to the grey tank .. I can see the pipe. Since the grey tank is vented to the roof there is no pressure issues and the low point in the plumbing is the shower.... personal exp . We run ours all the time with the grey tank closed, to get enough water to flush the black tank with no issues ( other than the overflow into the shower pan if you forget) I think it’s just cya for the maker since if you start a load with the tank full you could overflow the shower pan.

Probably a precautionary label. Do you know to which tank your washer drains & how many gallons that tank holds?

I don't leave our dump valve open when doing laundry. If our grey is over 1/2 full, I'll dump before I do a load of laundry just so I don't overflow into the shower pan, then close the valve. If under 1/2, I can do a load without dumping first.

The washing machine on my TS dumps into the gray tank and we have never had an issue with the tank drain being closed.

CYA message and to ensure the user knows to have the grey valve open and sewer hose connected. But if you know how to manage your grey tank, optional.
