Questions & Answers


Hi, there! We're sorry to hear this. As for the cap, yes. You can remove the cap to do some repairs but it will take a little bit of elbow grease because it is really tight. The Orbit 51017 has been discontinued for a long time but Orbit says that the manual for the Orbit 57065 (the automatic version) is applicable to this model. The only differences are the manual and automatic function but everything else is similar. Orbit also mentioned that you may have to fix/change the gasket to stop the leaks. May we recommend the Orbit 53066 3/4" and 1" anti-siphon repair kit. Just click Add to Cart and enter your zip code on the next page if you're interested in purchasing this item. Hope this helps. Thank you and we hope to see you again here at!
