    Hello everyone,

    I need help with something that has bothered me for several years, I have a very large yard. About 26 valves. ( in several locations.)

    25 are working fine it’s only one that’s giving me problems.

    There is a group of 7 valves ( water master ) – they are all running the same type of sprinklers and the same distance from the pump, one valve as very little pressure – I replace the inners and it work ok for a day or two now its has low pressure again.

    What the heck is the problem.

    The valves are all the same height and the sprinklers are also all the same height as the rest of the yard ( they rest of the yard all works fine )

    Check the lines for foreign materials like stones or sediments. Try flushing your lines with the sprinklers disconnected
