Thanks, but I'm not James, I'm George.

Have a look at Dave's post on a DIY for the valves :

Or, since you are in Homestead, FL and will never need a heater, just cap off the hose.
( cut the hose just before the valves, put something round, solid and about 2" long in between the 2 and clamp it up. )
