Default Rialta Water Heater

Just purchased a 2005 Rialta....Cannot get any hot water....the Top dischare pipe from the water heater is hot and the Relief valve is hot, so I feel the heater is working....I have found the two values as shown in the info and still cannot get hot water......I have also worked the relief valve to relieve the air in tank......but still no hot water......any suggestion will be greatly appreciated......I feel that I am missing a valve somewhere.....the hot side of the facuet runs cold water good....just not hot.

I have a bypass valve on mine.

Since I use mine once every blue moon, I leave it bypassed, with the drain open. I still flush it regularly, even though it's not used.

Although bypassed, I still get water from the hot tap, but it's not hot.

By-pass valves would be located very near or right at/on the water heater inlet and outlet.

I've seen:

Single valve - would also require a check valve
Two valves
Three valves

bypass setups.

I'm not familiar with Rialtas though.

My Bypass is at the inlet. Water line in, then splits to two. I missed it a few times because it's against the steel brace. I thought it was routed through the brace, but when I put my finger around it, I felt the lever underneath. The valve looks like it goes through the brace, but it's actually tight against it.

Note; With the valve on I get hot water. With the valve bypassed, I still get water flow from the hot tap, but it's not heated.
