2psquared Report post Posted January 22, 2023 Water in heater plenty hot. Just getting tepid water in discovery 08. Thought it was checkalve but now I am not sure it has one. It does have a mixing valve and think the screens might be clogged. Just looking for a heads up before I decide if I can fix it or have a repair done.

rayin Report post Posted January 22, 2023 On this parts list #18 is the mixing valve. If the eco-thermostat is allowing the water temperature to reach 130-140°F it is working OK, if the water temperature, as measured when draining a bit into a cup already containing a thermometer is lower than 120-130°, the thermostat should first be checked to insure it is lying flat against the tank, otherwise it should be replaced. These are all DIY projects, just take care not to get scalded. Share this post Link to post Share on other sites
