Eric was great, he was friendly and on time. My job ended up being bigger than I originally expected and he showed me the issues and explained what was necessary without BSing me. Would definitely use again in the future.

    Of the three sprinkler repair companies I contacted, Hessenauer was the only one to respond. They provided a date and time, and they arrived on schedule. They did a thorough inspection and fixed multiple problems for a reasonable cost. They are now my "go to" sprinkler repair company.

    Eric has been out here twice to correct everyone else's mistakes and I am so grateful.  I finally have my irrigation system working as it should.  This is a quality company with excellent workers who know their stuff. I'm glad I found them.

    Eric was out today to repair 3 valves damaged by a lightning hit.  Was on-time, communicated his arrival, and clearly explained the problem.   Very professional.  Emma also was a pleasure to deal with when making the appointment.  Will definitely use them again.

    Could not have worked with a better team. They came out, heard what I wanted, then validated that it was needed, and gave me a quote. They did a lot of repairs on my old system and it is up and running again. I could not have been more impressed with their timeliness, professionalism, and attention to my specific needs as an old home. I will use them again when needed.

    I was impressed with Hessenauer Irrigation.  Jay did a great job replacing an old irrigation clock.  He didn't stop there, he checked each of my 4 zones and replaced a few heads that needed to be replaced.  I'm saving their contact info and will definitely use them next time I need any work done!

Installing a reduced pressure zone backflow assembly is absolutely necessary for any irrigation sprinkler system in the Orlando or Central Florida area. This type of backflow assembly protects the potable water system from cross-contamination by preventing reverse flow from back-siphonage or back pressure.

When a reduced pressure zone backflow assembly is installed at either your home or business, it will most likely need to be installed on Schedule 80 PVC, galvanized, or copper pipe & fittings to comply with local code. The reduced pressure zone backflow assembly must always be installed with the relief valve outlet at a minimum of 12 inches above grade but must not exceed a maximum height of 3 feet.

Any backflow assembly must be tested annually to comply with local code. They must be tested by a state-certified backflow tester with a pressure differential type gauge. If the backflow fails the test, it must be repaired by a state-certified tester that is also certified to repair the unit. The results must then be logged with your local municipality by the test/repair contractor.

If you have a reduced pressure zone backflow assembly installation at either your home or business that requires an annual test, please call Hessenauer Sprinkler Repair & Irrigation on 407-302-2227 to make an appointment. We carry out backflow tests & repairs within the Orlando or Central Florida area. If a backflow assembly is not installed at your property, we can recommend & install the correct type to protect your potable water supply from contamination for your irrigation sprinkler system.
