changing water heaters


I live in a mobile home and the water lines are "plastic". The 3/4" water lines have a compressed fitting to connect the water lines to the flex copper lines going to the water heater. As you can see, the water connections on the tank (40 gal) are on the sides of the tank, one at the top area of the tank and one at the bottom area. The new tank (55 gal) has both connections coming out of the top of the tank, not the sides. Is there a way to extend the current lines by using couplers or extensions?

I'm total electric, and I'm very novice when it comes to this kind of plumbing, but this was my initial thought......Take two short 3/4" pieces of galvanized pipe threaded on each end....attach the existing water lines to one end of the pipes....then attach new flexible copper lines, let's say 18", to the other ends of the pipe and connect the new line to the water heater. Is this a workable solution? By the way, the water heater is in its own enclosed closet so there's no chance of anyone accidentally touching the hot line.

Your new water heater is not rated for mobile homes, return it and get the correct model. Also do not connect with galvanized, it will cause galvanic action and corrode quickly.

That would make a change-out very simple, and we have a home depot fairly close to us. Thanks.
