Toro TR50 Hi-Pop Severe Leak

I installed two Toro TR50 Hi-Pop heads (same zone) to replace a standard TR50s so that I could spray over nearby plants. Both spouted water around the pop-up shaft, spraying very little. Nice fountains, but not exactly what I had in mind. I have had no response from either my installer from who I bought the heads (I did the replacement - a simple exchange of TR50 rotor heads), and nothing at all from Toro. Nice service.

Can you help me understand the problem? Or are these rotors perhaps defective? I had to pull them immediately and return to the standard rotors.

The heads are either missing their wiper seals, or the cap that holds the head together is loose.

Water pressure may be the issue. Pressure sufficient to pop up a standard head may not be enough for a hi-pop head. The zone may need to be re-nozzled, to bring up the pressure.

Toro TR50 Hi-Pop Sever Leak

Thanks for both of your replies. I will check my units for the wiper issue, and will talk to my installer about pressure. I have a work-around in place now that satisfies my needs. Both units were to serve a vegetable garden, and I intend to replace the two with a drip system next spring. I do have a couple of other places where those hi-pop units would be useful, so solving the leakage problem would be most beneficial. I sure wish that I'd known of this forum a year ago. Again, many thanks.
