No water coming from FW tank

[Kandy]

2011 Heartland Landmark Augusta. We had a no water situation last October as there was no hot or cold running water. Found out that the HWH outlet check valve (brass) had come apart. Took out all of the loose parts (O-ring and a white plastic plunger) and had HW after awhile. I ordered the new check valve from Heartland (now only plastic check valves available). I installed the new upper check valve and all works fine on CITY water connection. I put filtered water into the FW tank (2/3 full) and turned on the FW pump and no water is running in the system. I had replaced the FW pump (5.7 Smart....) with the recommended Shur Flow 4048 last summer and all worked fine until the HWH outlet check valve failed. I took out the new water pump and it pumped water out of a container of water +- 3 feet lower than the pump. I have not yet reinstalled the pump and am wondering if there are any thoughts that might solve the issue.

Hi Kandy,

The output of the pump is teed together with the city water near the hot water output. Is it possible that a line was kinked or otherwise disturbed when the check valve was replaced?

Btw, you might want to order another brass check valve. The plastic valves have a history of developing leaks. Here's a link.

You'll also need a short 1/2" brass close nipple to convert the female fitting on the check valve to a male fitting.

Dan: Thanks, I'll try that. I need to check to see if a line is kinked.

After you turn the pump on, open a faucet and leave it open for the air to escape the system. This can take a while depending on how much air is in the system. Do the same for the hot side. Also make sure your winterizing valves are in the correct position.

If the hot water tank is empty that will fill first when you turn on the pump.
