What can you safely check yourself before slab leak detection in Kansas City?
A reasonably handy homeowner can spot warning signs: listen for running water with fixtures off, check the water heater or meter for movement, and look for warm spots or damp flooring on the slab. What you should not do is open floors or concrete or work on piping yourself.
Why slab leak repair is beyond DIY in Kansas City
Kansas City requires a permit before most plumbing work, and only minor jobs like replacing a faucet or clearing a stoppage are exempt. Work that opens, alters, or replaces piping needs a permit and inspection, and piping under a slab must be inspected before concrete is poured over it.
When to call a pro for slab leak detection
Call a pro if you hear water running with everything off, see warm spots on the floor, notice damp carpet or warped flooring, or your water bill jumps for no clear reason. Any repair involving pipe access or replacement under the slab also needs a licensed contractor.
