Citrus Heights gets most of its rain between November and March, about 21 to 22 inches in a wet year. Rain does not create leaks out of nothing, but it finds weak joints, swells Fiddyment soil under slabs, and turns small problems into visible ones. Winter is also the season that hides leaks, because a wet yard looks normal even when a line is broken.
Why leaks show up after wet winters
Fiddyment soil swells when it gets wet and shrinks when it dries. That cycle moves the slab a little each year, and the movement stresses pipe joints that are already old. Copper lines under slabs crack at stress points. Polybutylene joints from 1978 to 1995 give out. The leak was often waiting for months. The wet season is what finally opens it enough to notice.
Rain hides leaks. Here is how to tell
A yard that is wet everywhere after rain is just rain. A leak looks different: one strip stays soggy days after the rain stops, or one patch stays greener than the rest while the lawn dries out. The bill is the tell that rain cannot fake. A bill that jumps while use stays flat means water is going somewhere. A meter test works in any weather and settles it in two minutes.
What to watch from November to March
Watch the bill first. Then warm spots on the floor, cracks that widen after a wet stretch, musty rooms that never quite dry out, and one strip of yard that stays green through winter. Any one of these alone is a hint. Two together mean test the meter before the season ends.
Pools and irrigation in winter
Rain adds water to a pool and cool air slows evaporation, so the level moves for reasons that have nothing to do with a leak. Bucket tests mislead in rainy weeks. Wait for a dry stretch before trusting one. The irrigation system sits off all winter, so irrigation leaks wait quietly for spring startup, when the first run shows them as geysers or fogging heads.
Does cold weather burst pipes here?
Freeze risk is minor in Citrus Heights, but a hard cold snap can still crack an exposed hose bib or a line in an unheated garage. Disconnect hoses before a freeze warning and cover exposed bibs. If a bib splits, it usually shows as a wet wall or a puddle near the foundation on the first warm morning.
How the company tests a winter suspect
The company starts with the meter test, rain or not. If the dial moves with all water off, the next step is isolation: house versus yard line, hot versus cold, and the irrigation valve shut to test the zones. Acoustic listening goes on the section that fails isolation. A yard line break shows as a narrow strip of wet soil or one green patch that outlasts the rain. The company marks the spot before anyone digs, so a winter repair opens one place, not a trench across a wet yard.
What to do when you suspect a winter leak
Run the meter test first. Rain does not change the reading. Note the pattern: one spot or everywhere, and when it started. Call with the bill change, the spot, and the date. That list points the testing at the right section from the start, and a winter leak found in January costs less water than one found in April. Tell the company four things: how much the bill changed, where the wet spot or warm spot is, when it started, and whether the spot stays wet days after the rain stops. That last detail matters most in winter, because it separates a leak from rain in one sentence.
If a winter leak damages floors or walls, photos and the detection report are what the insurer asks for first. Insurance coverage moves faster when the evidence is already in hand.
Frequently asked questions
Does rain cause slab leaks?
Rain does not break a sound pipe. It swells the soil under the slab, and the movement stresses joints that are already old or weak. The leak was waiting. The wet season exposed it.
My yard is soggy after rain. Is that a leak?
If the whole yard is wet after rain, that is rain. If one strip stays soggy days after the rain stops, or one patch stays greener than the rest, run the meter test.
Can the meter test work in the rain?
Yes. The meter box sits at the curb, and the test only needs every fixture off. Rain does not change the reading.
Should I wait until spring to check a suspected leak?
No. A pressurized leak runs around the clock and does not pause for winter. Waiting lets water keep moving under the slab.
Why does my pool level keep changing in winter?
Rain adds water and cool air slows evaporation, so the level moves for reasons that have nothing to do with a leak. Wait for a dry stretch before trusting a bucket test.
