How to turn on sprinkler pump? (novice=may be an easy answer!)

chatguyApril 14, 2010

Hi All,

I'm a new homeowner with an underground sprinkler system, that also has a pump (due to low pressure of city water). Although I've opened up sprinkler systems in other homes before that don't have a sprinkler pump, I do consider myself a novice. Currently, water does flow through the sprinkler heads, but with low pressure, while noticing the pump not turning on.

I noticed the pump is connected to a relay box, which is also connected to the sprinkler control box. The control box and the relay are both plugged into a working outlet, but the pump does not turn on....making me think there is a simple switch to turn it on, that I'm not finding? If so, would anyone know where I can find that switch?

The pump is: Myers model # RJ50S (The sprinkler control is Rain Dial RD900-INT).

Would anyone know how to turn on the Myers RJ50S pump, or where the pump's on/off switch is?

Hi chat,

You should have a motor control box and a electrical disconnect box. First I recommend just having a licensed electrical check it out. Why. Things go wrong and liability. Electricity is deadly especially if your pump is big enough to be a 220 or 240 volt pump and with a licensed electrician if the fix doesn't work he can come back and fix it. The piece of mind is worth it. With that said, it might be a blown fuse or the disconnect is open. After checking the disconnect box and you believe it is okay. Check the route of the electricity to the Motor control box and make sure your lines are hot to the motor control box on/off switch. This can also be on your controller as the motor control feature. Try the on button. If things don't work, you probably have a short in the pump wiring and you need to call the electrician and have him pull the pump and check the wiring. This is a generic take on it without looking through your operating manuals. good luck. I hope you have those. JMHO Aloha
