We have done it that way before. Just a dab of silicone sealant works great. Now we wire don't go through the hose and we wire everything with regular 3 prong plug in ends. When we connect them where cows might get at them, we just use electrical tape around the connectors and tape the cord to the hose. If we need to stretch out the hose or the water source shrinks back, we can then use a chunk of hose and add a regular extension cord to stretch the power out.
