Jenks, OK: what's different here
Jenks is a suburb of Tulsa in Tulsa County with a population of about 26,017 as of the 2020 census. Many homes there are in a metro housing market where sprinkler systems and outdoor backflow devices are common. Jenks sits about 11 miles from Tulsa, roughly a 15-minute drive via the main highway. The area sees freezing weather, with a mean first hard freeze around November 14.
Can a frozen backflow preventer be repaired or must it be replaced?
It depends on what cracked. If only the bonnet, a test cock, or another internal part cracked, the device can often be repaired in place. If the body cracked from freezing, the device typically has to be replaced.
How long does frozen backflow preventer repair take in Jenks?
A typical backflow repair or rebuild is often completed in a single visit, usually within 1 to 2 hours. Some providers can test a device in about 30 minutes and repair it on the same visit if it fails.
When does freezing weather hit the Jenks area?
Tulsa's mean first 28°F hard freeze is November 14, and the mean last one is March 17. The mean first 32°F frost falls on November 3, with the mean last occurrence on March 29. A device left full of water all winter is a common reason it fails the spring test.
Should the repair price be in writing before work starts?
One repair-oriented provider prices repair or rebuild work after a failed test in writing before any work starts. Ask the pro we refer for a written price before authorizing the job. Also ask whether a retest is included after the repair.
What to do next
- Ask the pro to confirm whether the body or only an internal part cracked, since that decides repair versus replacement.
- Request the repair or replacement price in writing before any work starts.
- Ask for proof of license and insurance before the pro begins work.
- Ask whether the device will be retested right after the repair, as some rules require.
