| Has anyone had a problem with their water pump stopping when using the hot water? It works fine with the cold but when you turn on the hot it quits. Hate to buy a new pump if that isn't it. |

That is weird! I have never heard of that before. If it works when using cold water then the pump is just fine. There is something else wrong. Do you get hot water when you are hooked up to a outside water supply and pump turned off?

Do you have the valve on the hot water line, behind the water heater, opened? The system gets pressurized on the cold water line so if the hot water valve and the bypass valve are both off the water pump will turn off once the water lines and hot water tank are pressurized. This is what may be happening:
water tank ----> water pump ----> cold water line to hot water tank ----> hot water tank ----> hot water line out ----> valve (closed) ----> hot water line to faucets ----> faucets
In summer mode the hot water and cold water valves behind the hot water tank should be on (parallel to the pipe), and the bypass valve between the hot and cold pipes should be off (perpendicular to the pipe). ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

| Anything blocking the pipes leading to or from the hot water heater? |

| It will run for a few seconds then the pump shuts off. Maybe something internally in the pump? |

If it pumps fine when a cold water faucet is open (as you indicated above), its not the pump. That narrows it down to something on the hot water side. Check to see if it does this on the sink faucet and the shower faucet. If only one of them does this you have a blockage in the hot water faucet or somewhere in the line to that faucet. If it does it on both, check the bypass valves behind the water heater (as I indicated above). ------------- Doug ~ '10 171 (2009-2015) ~ 2008 Salem ~ http://www.rpod-owners.com/forum_posts.asp?TID=1723 - Pod instruction manual

| He hasn't changed anything there since our Alabama trip and we used the pump then. The shower and kitchen sink on hot stop working. |

| I vote with Treck. I think it is blockage especially if you did not change anything. |
