Replacing a Water Heater

by Barry and Cindy 1997 U270 36'

Removed original hot water tank. We cut open the 2-1/2 year old tank to learn what happens to the inside in two years.

Installed new 10 gallon gas & electric Atwood hot water tank.

Cold water supply changed from top of plumbing manifold to a cold water manifold valve

Hot water from tank changed from top of plumbing manifold to a hot water manifold valve.

Two top water manifold plumbing connections capped off.

A new hose ran from cold water manifold valve to hot water manifold valve to bypass hot water tank for winterizing.

Replaced all original water pump plumbing from bottom of fresh water tank to bottom water manifold bottom connections.

Ball valves installed on input and output water pump hoses to allow water pump to be replaced without having to drain fresh water tank or drain kitchen & bath water lines.

Installed a permanent water pressure gauge to monitor water pump output, city water pressure & hot water tank expansion psi.

Rerouted fresh water tank overflow hose from running over rear bulkhead to flowing through floor far from bulkhead.

Original pump area has grown to a maze of plumbing connections & hoses. Blue expansion tank was removed a long time ago, but its blue wall mounts were still in place.

Replacing Water Heater

All plumbing from fresh water tank to bottom of water manifold was replaced. All holes in floor sealed to keep water leaks from bulkhead & inside floor. New plumbing held in place with Velcro to eliminate screws into floor. Pump new: New plumbing hoses, fittings & valves

Sharkbite plumbing fittings used with new permanent water pressure gauge

Replacing Water Heater

New hose connected to cold and hot sides of water manifold. Both valves are normally closed, and opened only to bypass hot water tank for winterizing or in case of hot water tank leak at which cases the valves connecting hot and cold water lines to tank are closed.

Replacing Water Heater

Original hot water tank was connected to top of water manifold, eliminating any way to shut off the hoses for winterizing or if there was a tank leak. New tank has its water connections at water manifold valves and manifold top connections were capped.

Replacing Water Heater

Original fresh water tank overflow went out back of bulkhead and wet bottom rear bulkhead, which promoted rust. Hose was re-routed

Replacing Water Heater

Fresh water tank overflow routed to water manifold area hole in the floor. Original rear bulkhead hole capped off.

Replacing Water Heater

New fresh water tank overflow hose was run through floor to keep water from flowing over rear bulkhead
