RV Winterization
Protect your RV from Ohio winters. Our winterization service drains every line, blows out
your fresh-water system, and fills your plumbing with non-toxic antifreeze — so you
don't spend spring repairing what you could've prevented in fall.
Every spring we see the same thing in the shop: RVs that sat through winter without proper winterization and cracked like an ice tray. Water heaters split at the seams, PEX runs ruptured behind the skin, pumps that spin but won't prime. All of it is preventable — and a Post's Traveland winterization costs a small fraction of what spring repairs do. Schedule before the first hard freeze.
Why an RV Freezes Faster Than You Think
Ohio winters punish RV plumbing in ways most owners don't expect. Water doesn't need to freeze solid to cause damage — a single cold night below 28°F can crack a PEX fitting when trapped water expands with nowhere to go. Water heater tanks, low-point drains, outdoor showers, and P-traps under the sink are usually the first victims.
And the damage cascades. A split fitting behind the wall drips into insulation all winter, and by summer you've got delamination, soft subfloor, and mold. One overlooked line can turn into a repair bill the size of a new roof. Winterization isn't optional in this climate — it's insurance.
The Five-Step Winterization
Proper winterization isn't just "pour antifreeze in." Every RV that comes through our bay gets the same five-step protection — in order, every time.
Drain & Purge
We empty your fresh tank, grey tank, black tank, and water heater. Any trapped water becomes a winter weapon — so every drop comes out first.
Blowout
Low-pressure compressed air pushes residual water out of every PEX line, faucet, shower valve, and outdoor fixture — the stuff drains alone can't clear.
Bypass the Water Heater
We route antifreeze around your water heater tank — saves roughly six gallons of antifreeze and protects the anode rod from chemical damage.
Pump Non-Toxic Antifreeze
Pink RV antifreeze pumps through every supply line, fixture, and appliance — until it runs clean-pink at every tap. Safe for your fresh-water system in spring.
Seal & Store
P-traps topped off, low-point drains closed, exterior hatches checked, and a spring to-do list tucked into your glovebox so de-winterization goes just as smoothly.
Don't Forget the Spring Wake-Up
Winterization is only half the job. Come spring, your RV needs to be de-winterized properly before the first trip — fresh-water system flushed clean of antifreeze, water heater refilled, lines pressure-tested for any hairline leaks the cold may have revealed, and every fixture checked for clean flow.
Book both services together in the fall and we'll hold your spring slot automatically. Family-operated since 1956 — we're the ones who built the relationship; we're also the ones who pick up the phone when it's time to wake your RV back up.
