Just discovered this Chronic leak and wondering if anyone can recommend a contractor who can replace the vacuum valve.

See photo attached.

Thx,

You can get repair kit for few bucks in you know model number, very easy to reseal.

Amazon.com (https://www.amazon.com/720A-Pressure-compatible-Backflow-Preventer/dp/B0BGBYDKH1/ref=asc_df_B0BGBYDKH1?mcid=177760cb5af73e389fa3d79 327488806&hvocijid=3556701401619605262-B0BGBYDKH1-&hvexpln=73&tag=hyprod-20&linkCode=df0&hvadid=721245378154&hvpos=&hvnetw=g&hvrand=3556701401619605262&hvpone=&hvptwo=&hvqmt=&hvdev=c&hvdvcmdl=&hvlocint=&hvlocphy=1027028&hvtargid=pla-2281435176938&psc=1)

Mind had lizard caught in it preventing it from sealing all way. Take cap off and look see if anything stuck?
