how do I access the fittings on tbe water heater. I can see a leak either the blue or red hose going into the insulated water heater. is there a utube video on how to get to those fittings. I have trouble turning the valve off for water going into water heater and now there is water spraying out of the blue hose connection.. how do I get to it to repair. my hands won't fit anywhere in there. do i take the styrofoam insulation off to get more room so I can repair the fitting. no idea. or should I take it to bish rv repair in bozeman,mt.. and let them repair it
