Inline valves installed below grade or above the ground are suitable for use with any water quality. Water from a lake, well, open ditch and other dirty water source may contain particles, rocks, sand and other debris that can get into the valve and cause it to malfunction. In order to protect the valve, a filter with 80 to 120 mesh is suggested. If you have a problem with your valve, you may need to turn the water supply off and disassemble the valve to find the problem. Most of the time, the glitch will be around the diaphragm with problems such as a rock piercing the diaphragm or the diaphragm becoming plugged. If you find the problem, you can use one of our 3/4" through 2” diaphragms as a replacement.
