Eddy, I'm trying to see what happens when two zones are operating at the same time, but can't figure out how to do that. I can start only one zone at a time from the timer/control box. The new valve the repairman installed has an "On/Off" lever, so I can start that one at the valve, but the other valves only have a type of screw lever at the top of each - I've turned them but nothing happens. In the next few days I'm going to randomly turn the lawn zone on through the valve lever (not the control box) to see if the pressure varies when started that way. This morning it was very strong and worked perfectly. I am going to google "porting problem" - though I'm not mechanically minded, it sounds interesting :o) Thanks for your help! Linda The new valve has an easy "on/off" lever.

You can flush the head by removing the nozzle and turning the zone on for a few seconds. If water comes shooting out, then the blockage is either gone or was never the problem. Also, check the filter under the nozzle for debris.

I purchased a Fire Hydrant Spa showerhead from Water Managent-Take A Shower and it is chrome colored plastic. The nozzle isn't even metal and I can't get a hold of them to return it. This prduct is junk.

is it both the hot and cold or just one of them? could be a clog in the faucet itself. remove the aerator and run it for a with both taps minute wide open. if this doe snot help it, you may need to remove/disassemble the faucet to clear it. could be crud built up inthe shutoffs too. try to close then open them a coupel times to see if they go back to working. i usually leave the tap running with the aerator off when i have had to do this at our old house.
