Re: Water Heater
I don't see any problem using a regular water heater, except that it may be a challenge to find one that fits in the available space. A family member lived in a trailer where the water heater was accessed via a door on the outside. When the water heater needed replacing, it was discovered that the water heater would not fit through the door. Replacement required demolishing part of the bathroom -- which needed to be done anyway because the shower "enclosure" was Masonite panels covered with vinyl and not well-sealed which led to rot.
If the supply line has a standard outside diameter according to the table below, you can use "Shark Bite" type fittings to adapt and extend it to the top of the tank.
Nominal = Actual outside diameter
3/8" = 1/2"
1/2" = 5/8"
5/8" = 3/4"
3/4" = 7/8"
1" = 1+1/8"
If you have 5/8" nominal pipe (3/4" outside diameter) you may have a hard time finding an appropriate fitting; it's kind of an odd size.
Be sure to set up the T&P relief valve so that it drains to the outside or underneath. By code, the end of the T&P pipe should not be threaded.

The "Senior Member" designation under my name doesn't mean I know a lot, it just means I talk a lot.I've been a DIYer since I was 12 (thanks, Dad!). I have read several books on various home improvement topics. I do not have any current code books I can refer to. I was an apprentice plumber for two years.
