After reading several post about the in line water filter in the A-frame and the trouble I had removing the canister I decided to remove the filter and canister and connect the water line with a 4 inch piece of sch 80 grey pvc pipe. I noticed on the small piece of pvc pipe it said for "Outdoor Use Only" has anyone come across this? Does that mean it cant be used with portable water? I bought it in the sprinkler section of the hardware store.
