Yo. ur thoughts please-
I have completed installing the drain pan hose. I actually ran it along next to the frame and under the shower and out the shower drain hole into the front well. I used a 1/2" ID water hose connected to the pan with a 34-1/2" burr. To test I put water in the pan to make sure it would drain. It drains OK but, I am concerned in the event of a major leak the1/2" hose will not evacuate fast enough.
I have not installed the washer yet - should I change to the standard hose?
Not sure what you mean by "standard hose". Our washing machine was installed at the factory and they used 1/2" tubing for the overflow pan drain.
On our Splendide stackable, the fill cycle runs for maybe a minute. A very good water flow would be 5 gallons/minute, so the washer might use up to 5 gallons of water when it fills. Often less because water flow is less. Our unit has a timed water fill. If the water level is too low to wash, operation stops. So in a worst case it might dump up to 5 gallons into the tray and then stop running because no water is in the tub.
I think the overflow pan probably holds around 2.5 gallons. If the fill cycle adds 5 gallons in a minute and your drain line drains 2.5 gallons per minute, the tray would probably still contain the entire leak. If not, your carpet would need to be dried, but I don't think it would be a catastrophic situation. And of course the worst case scenario is very unlikely.
Winterizing the washing machine correctly is key to preventing leaks. Our
Winterization Guide has instructions. In a mild climate, you could use compressed air with confidence, adding a little antifreeze for the drain and p-trap. For very cold climates, you might want to follow the antifreeze method all the way.
