What is the 50% rule for repair vs. replace?
Repair when the fix costs less than half the price of a comparable new model and the unit still has several years of life left. One guide adds a second test: replace if the repair exceeds 50% of replacement cost and the unit is more than 80% through its expected lifespan. If a repair approaches the cost of a new unit installed, replacement usually wins.
How much do common appliance repairs and replacements cost?
Typical repair costs run $150–$400 for refrigerators, $180–$250 for washers, $100–$430 for dryers, and $75–$600 for dishwashers. Replacing costs more: about $600–$2,300 for a refrigerator, $500–$1,000 for a dishwasher, $700–$1,300 for a washer, and $800–$1,200 for a dryer. Those gaps are why younger units usually justify repair.
When should Tulsa homeowners repair a backflow assembly instead of replacing it?
Repair makes sense when the assembly is relatively young, the fix is well below half the replacement price, and there is no safety issue. Oklahoma’s plumbing code requires testing at installation, immediately after any repair or relocation, and at least once a year. Factor that required retest into the true cost of a repair.
How does Tulsa weather affect backflow testing and repair decisions?
Freeze damage is a real local risk: Tulsa’s mean first 28°F hard freeze is November 14 and the mean last one is March 17, with a mean of 241 days between hard freezes. Exposed plumbing and backflow preventers can be damaged by freezing temperatures, so winterization timing matters. Freeze-damaged assemblies may tip the math toward replacement.
Who can test a backflow assembly in Tulsa?
Oklahoma has no statewide backflow tester license; each city or rural water district approves its own testers. Many require ABPA or ASSE certification together with a Construction Industries Board plumbing license. The City of Tulsa requires testing by a City-approved Back Flow Assembly Tester before acceptance.
