The check valve on the solar return line prevents the panels from being pressurized/filled with water when they are turned off by the diverter valve. Typically a "leaky" valve is used for the diverter valve so that the solar supply line can drain when the pump is off.
To begin installing a check valve, check the following steps to ensure accuracy: Ensure pipes are clean and debris-free before installation. Move the flapper by pushing it away from the seating surface to ensure free movement. Identify the arrow on the valve indicating the flow direction.
Install a shut-off valve for the solar system so that the cold water supply is not interrupted. Install a T&P Relief Valve. The drain line should be discharged the to the outdoors no higher then 6″ above grade. Install the pump on the collectors feed line with the arrow pointing to the direction of flow. (To collectors)
Yes, check valves can be installed vertically, depending on the type. Note that the arrow on the check valve indicates the proper positioning concerning the pipe's flow; for vertical installations, ensure the flow arrow points upwards. When installing a check valve, precision and adherence to proper procedures are paramount.
Can You solder pipe fittings with check valve installed?
WARNING: Do not solder pipe fittings with check valve installed. This will result in heat damage to plastic and rubber components of check valve. 1. See Installation Instructions Maintenance-Free Circulators. Remove union nut, gasket, tail piece and check valve from packaging. Slide union nut onto discharge piping.
How do I install a thermosyphon prevention check valve?
Install a thermosyphon prevention check valve on the collectors return line. Install the tank sensor on the threaded stud located behind the cover plate of the bottom portion of the tank. Mount the automatic controller on the tank or next to the 110V outlet.
How do check valves work?
Check valves play a vital role in fluid systems by permitting flow in one direction while preventing backflow. When considering installing a check valve, it's essential to understand the right process. Installing check valves involves several key steps to ensure optimal performance and prevent issues like water hammer.
