Check all the sprinklers, as a leaking sprinkler near the valve can cause a different sprinkler that is farther from the valve to not fully pop up. If there is leakage between the riser and the cap when the riser is completely up, the riser seal is bad, the riser is scratched, or ...
The consequences of poorly doing more complex jobs like sprinkler solenoid repair or valve replacement are much worse, so these tasks should always be left to the pros. The mid-range option If you can afford to fix more than just the most noticeable problems, we recommend it. Doing more ...
A shut-off valve, for use with a sprinkler head affixed to a riser pipe, including a valve seat affixed within the riser pipe upstream from the sprinkler head, the valve seat having an opening and imp
Alternatively, flow shut off valve 28 could be omitted. If this occurs, the relevant markings would be omitted from cover 22 as well. The Rebar Attachment Collar Sprinklers 2 of the type disclosed herein are sometimes used in installations where the sprinklers are not buried in the ground, ...

are thought to be superior. There are several reasons for this. For example, a pop-up sprinkler's nozzle opening is typically covered when the sprinkler is not in use and is therefore less likely to be partially or completely plugged by debris or insects. Also, when not being used, a po...
Complete shut off of the water flow normally only happens if the nozzle 18 is plugged, or if the tubular structure 40 is completely closed off such as by turning a manual shut-off actuator mechanism described hereafter in conjunction with FIGS. 13-24. Another example of a shut-off valve ...
The use of temperature sensitive magnetic materials provides a reliable, self-actuating opening and closing valve not requiring any external power sources and having a cost effectiveness similar to existing sprinkler heads. Additionally, the size configuration for the sprinkler head for new and retrofit...
The cylindrical housing 21 has an inlet port 22 into which fluid is transmitted. In the passive state, the spring 18 abuts against shoulder 15 of the valve ring 13 to urge the riser 10 downwardly to be completely surrounded circumferentially by the housing 21. Fluid pressure transmitted from ...
