I want to back flush my hot water line. I got some blockage near my shower valve so I think. Whole other story. I don't have a floor drain or any drain where the tank is. To drain the tank I would fill buckets and then throw it out the bulkhead. Instead of keep filling and empty buckets I thought of either connecting a hose to the drain and running out the bulkhead or connecting a hose to the hot water corrugated line and out the bulkhead. I prefer the corrugated line to avoid dumping any sediment in the new tank. Any for potential problems doing this?
