All the water outlets in my condo can only supply hot water for at most 2 mins and then I am left with cold water. I changed my gas water heater 2 days ago, but the problem continues. I was desperate when I thought the problem was finally resolved but was left with cold water again during a shower. Do anybody happen to know what is going on here ? Thank you a lot.
- Check the dip tubes on hot water heater.
- Isolate the hot water heater to make sure the heater was running properly.
- Turn off the radiant heat systems and bypass them with the built-in valves.
Open up each shower fixture and close off the water valves to take those out of the equation. If the hot water still run cold do next:
Remove the recirculating pump and check the system.
- Remove the check valves beginning with the one near the recirculating pump and discover the broken valve. If this still didn't work, they would've kept going to check every check valve in the system(three total).
Maybe it helps
