Greenville’s cooling season runs long, and by October most Upstate homes have had the air conditioner running since April with the plumbing quietly carrying a summer of showers, gardens, and cookouts. Fall does three things to a house here, and each one is a reason to walk through the plumbing before the weather turns. The leaves come down and find the drains. The air dries out and reveals the leaks that summer humidity hid. And the first freeze arrives earlier than newcomers expect, usually in late October or early November, to find the pipes nobody insulated. This checklist is organized around those three problems.
When the leaves come down
Fall leaves clog more than gutters. They work their way into yard drains and downspout outlets and slow the water moving away from the foundation, which puts extra strain on the sump pump and the sewer line during the next heavy rain, and heavy fall rain in the Upstate is not rare. Once a drain is partly blocked, that rain has nowhere to go but the yard and, on the red clay under most Greenville homes, into the crawl space.
- Clear visible debris from yard drains and downspout outlets before leaf season peaks, and again after the oaks finish dropping.
- If your home has a sump pump, pour a bucket of water into the pit and watch it start and drain. A pump that has sat idle since the spring rains can seize without warning, and November is a poor month to find out.
- Run each indoor drain and watch it empty, since a sink that drains slowly in October stops in November when the house fills with holiday guests. Our drain clearing visits are short ones.
When the air dries out
This is the observation most fall checklists miss. Greenville’s humid summers make it easy to overlook a small leak, because condensation on pipes, air conditioning lines, and windows looks very much like a slow drip, so a leak under a sink or behind a wall goes unnoticed for months. As the air dries in October, that background moisture disappears, and a leak that is still there stands out. Fall is the best month of the year to look.
- Open every cabinet under a sink and feel the supply lines and the trap, and look for water stains, soft spots in the cabinet floor, or a faint mineral smell.
- Look around the base of each toilet and at the floor around the water heater, and put a few drops of food coloring in each toilet tank, since color in the bowl after fifteen minutes means a flapper leaking around the clock.
- Read the water meter at bedtime and again in the morning with nothing running. If it moved, water is leaving the system somewhere, and professional water line leak detection finds where without opening walls room by room.
Before the first freeze
The Upstate does not see sustained deep cold, but it sees more freezing nights than the rest of South Carolina, and a night or two below freezing is enough to split a pipe that was installed for a warmer climate and never protected. The vulnerable spots are the outdoor spigots, the crawl space, the garage, and any line along an exterior wall.
- Disconnect and drain the garden hoses, since a hose left connected traps water in the spigot, and that water is what splits the pipe behind the wall.
- Fit insulated covers on the outdoor spigots and wrap any exposed pipe in the crawl space or garage with foam sleeves.
- Shut down and drain the irrigation system, and check the backflow preventer for drips, since it sits above ground and freezes first.
- Find the main water shutoff and turn it once to confirm it moves. A seized valve is a hard thing to discover while water is running across a floor.
If a pipe does freeze and split, our frozen and burst pipe repair team handles it, and our post on preventing frozen pipes covers the full routine, including what to do on the cold night itself.
The water heater, in any weather
Water heaters work quietly all summer, and by fall sediment has built up on the bottom of the tank. Rumbling or popping while the heater runs, water that takes longer to heat, or showers that run short sooner than they used to are the signs. A flush clears the sediment and helps the unit keep up once temperatures drop and hot water use rises. If the heater is past eight or ten years, or you have seen rust-colored water, a slow leak at the base, or a pilot that will not stay lit, have it looked at now rather than the week before the holidays. Our water heater team flushes and inspects both tank and tankless units as part of a fall visit.
What a professional fall check adds
Most of this checklist takes an afternoon, and a professional visit catches what a homeowner cannot see: a hairline crack in a drain line, a water heater a year or two from failing, or a pressure regulator that has faded. A typical fall plumbing visit from Carolina Heating Service covers the water heater, the exposed pipes and outdoor fixtures, a sump pump test where there is one, and a check for hidden leaks, with a camera inspection of any drain that has been slow. The technician tells you what was found and what, if anything, needs follow-up, with the price presented before any work begins, and the visit is recorded on video.
Scheduling before winter sets in
Carolina Heating Service has served Greenville and the surrounding Upstate, including Spartanburg, Anderson, Laurens, and Pickens counties, since 1981. Schedule a fall plumbing check online or through the 24/7 website chat, and you will receive a photo of your technician and an on-the-way message before arrival. Getting the plumbing looked at before the first hard freeze costs less than the repair after one.
