2022 310GK-R Gray Dump Valves

[SolarPoweredRV]

The 310GK has a 3" valve and pipe on one gray tank and a 1-1/2" valve and pipe on the other. The handles pull distances equal to the diameter of the valves. What you're experiencing is normal.

Rob,

Does your 310GK only have one grey tank?

Mine has 2, Kitchen and Bathroom/Shower.

Rob,

Mine has 2, Kitchen and Bathroom/Shower.

Ours is just like yours - one for the kitchen and one for the bathroom and W/D. That's why I said it had a 3" valve on one and a 1-1/2" valve on the other.

Thanks so much for the confirmation. Our shake down trip wen well with just a few nit picks so far. Came home to a Recall letter from Grand Design on the awning fabric… I hope it gets replaced… it is the thinnest looking stuff I have ever seen on an RV awning in 30 years

Our ‘22 310gkr, both grey pull out the same distance, about 4-5 inches.

Mine too. As long as it drains it should be no problem. My philosophy is if I can fix it myself I do it. Bring it to the dealer they fix one thing and break something else.
