shower pulsing

Shower worked well for first 18 months and now when shower is started the water from it is stop-start (i.e. pulsing), but after approx 2 mins runs fine. If stopped and started after only few minutes it's okay, but not so if off for awhile.



Checked the solenoid and its okay (3.98). All valves full open and water supply unchanged from installation. What's next to check as likely problem? Any help is greatly appreciated . Thanks

Forgetting about the temperature turn the shower from fully hot to fully cold at fully hot you should have not much more than a dribble coming from the hose and on fully cold you should have a good strong flow, if you do not have this difference then you may have a faulty flow/stabilizer valve.
