Round Rock Water Bill Up $80 Out of Nowhere? Here's the Hidden-Leak Checklist
Why $80 is a useful threshold
An unexplained increase of $80 or more on a Round Rock residential water bill usually means a hidden leak, and slab leak detection is the fastest way to confirm one in a Brushy Creek home represents roughly 10,000 to 15,000 gallons of additional water, depending on your rate tier. That is not seasonal variation from lawn watering. That is either a significant change in household habits or a significant leak. The checklist below helps you distinguish between the two before spending money on a plumber for a problem you can solve yourself, or before the bill gets higher because the problem was ignored.
Call (512) 737-6168 when the checklist finds nothing and the bill is still elevated.
Check the obvious sources first
Before the gauge test, check the easy things. Did someone fill a pool or hot tub this month? Did the irrigation schedule run more cycles due to the heat? Did a new appliance get installed? Was there a teenager home who took long showers every day? All of these add up to real increases. If there is a reasonable explanation, the bill increase is not from a leak.
If nothing obvious changed, run the dye test on every toilet in the house. Drop a dye tablet or food coloring into each tank, wait 15 minutes without flushing, and check for color in the bowl. Silent toilet leaks are the most common single source of unexplained water bill increases in Round Rock, and they are invisible without the dye verification. A toilet that runs for one second every 20 minutes loses surprisingly large amounts of water per month. Mark any toilet that shows color and plan to replace the flapper.
Run the meter test
Shut off every fixture, ice maker, and appliance that draws water. Go outside to the meter box and read the meter face. Wait ten minutes. Read it again. If it moved, or if the seep indicator exhibits intermittent spinning, water is leaving the system with everything off. That is a confirmed pressurized leak. Note whether the meter is inside the fence line or at the property line, and repeat the test with the main shutoff closed to determine which side of the valve the loss is on.
If the gauge does not move, the increase is likely from a fixture that was running more than usual, and the checklist above is the right next step. If the meter moves, the investigation shifts to finding which system is losing water. Call (512) 737-6168 once the gauge registers a loss and you need the source located.
Check under sinks and at appliance connections
With the meter confirming a leak, walk the house systematically. Open every cabinet under the sinks in the kitchen and bathrooms. A seep at a supply junction, a weeping pipe joint, or a dripping garbage disposal will show as moisture, water stain, or swollen particleboard in the cabinet base. Check behind the refrigerator if the ice maker is connected. Check at the base and the connections of the water heater. Check the washing machine supply hoses and the connection at the wall.
Also check the irrigation controller during a rainfall event. If the controller is in a cycle or if a valve is stuck open, the system runs whether you know it or not. Turn the controller off completely, not just to the off setting but at the main power, and check whether the meter indicator stops. If it does, the irrigation system is the culprit.
When the checklist does not find it
If the meter confirms a loss and the visible checks find nothing, the source is in the slab, an in-wall run, or the buried service line. These locations require acoustic detection equipment, thermal imaging, and pressure testing tools. Attempting to find them by opening floors or walls without confirmed location information turns a detection problem into a restoration problem as well.
An $80 increase today can surge to a $160 increase next month if the loss escalates or a second breach develops alongside the primary one. Addressing the verified source is the first step.
A pipe condition check after the repair prevents a second investigation on the same run. Many Round Rock homeowners find that assessing the pipe while the access is open costs far less than a second service call months later.
Detection work locates the source without destructive exploration. The alternative, opening walls or breaking concrete to search, creates restoration costs that dwarf the cost of a proper diagnostic visit. Call (512) 737-6168 and we can locate the source within one visit without opening anything until we know where the repair needs to go.
After the source is found: the repair and the verification
Once the source of the $80 increase is found, the subsequent stage depends entirely on what electronic leak detection revealed. A silent toilet leak gets a new flapper and a fill valve check. A leaking supply connection under a sink gets a replacement fitting and a dry-cabinet test. An irrigation valve that is stuck open gets the solenoid or diaphragm replaced and the controller tested through a full cycle. These repairs are fast, targeted, and directly connected to the loss the bill showed.
A slab leak, an underground service break, or an in-wall supply rupture are bigger repairs, but they follow the same principle: fix the established source and verify the fix before closing any opening. For a slab correction, that means coring the concrete at the confirmed location, replacing the failed section, and pressure-testing the repaired run before patching the concrete. For an underground line, that means excavating the single confirmed break, replacing the failed section, backfilling in layers, and verifying with a final meter test before leaving.
Verification is what separates a complete repair from an incomplete one. After any supply-side correction, we run the meter test again to confirm the indicator has stopped spinning and the dial is static with everything off. A meter that still moves after a repair means a second leak is present, or the repair did not fully address the source. We do not leave a job until the meter confirms the loss has stopped.
A completed repair should prolong the savings and bring the next bill back to the baseline. If the bill remains elevated after a repair, run the meter test again to confirm the fix held.
A bill that comes down but not all the way to baseline suggests a secondary loss remains. Call (512) 737-6168 if the statement went down after a repair but not fully to the prior level. A residual elevation after a confirmed repair often means a second source was running alongside the primary one. A subsequent meter test with everything shut off confirms whether another pressurized loss is still active. If the indicator spins again, the investigation continues from where it left off, with the first confirmed source already eliminated from the search.
A two-source investigation on the same day costs less than returning for a second full visit weeks later. A repeat meter test with everything off confirms whether another pressurized loss is still active. If the indicator spins again, the investigation continues at no additional diagnostic charge.
