How We Close & Winterize Your Inground Pool

Credible Pool & Spa Pool Winterization — protect your pool all winter long

Closing an inground pool has exactly one job: make sure no water is left anywhere it can freeze, expand, and crack something. There is more than one way to get there — and if you have owned a pool before, or came to us from another company, our method may look different from what you are used to. That is okay. Here is exactly what we do, why we do it this way, and why it fully protects your investment. (This page covers our inground pool closings.)

How We Winterize — Step by Step

  • We lower the water to the correct level for your pool and cover.
  • We blow out every plumbing line with compressed air through the skimmer, then plug all the lines (skimmer and returns) so no water can sit in the pipes over the winter.
  • We add pool-grade antifreeze to the lines as a backup barrier against any last trace of moisture.
  • We open the drain plugs on your equipment — pump, filter, and heater — so any water inside drains out completely and has nothing left to freeze.
  • Everything above the waterline gravity-drains on its own. Water always finds its level, so any plumbing above the pool’s surface empties itself right back down into the pool.
  • We winterize your water chemistry and install your safety cover.

When we are finished, there is no standing water left anywhere the cold can reach it.

Why We Don’t Take Everything Apart and Store It in a Shed

You may have had a company — or an older, now-retired owner — who pulled the pump, filter, heater, and chlorinator apart every fall and carried them off to a garage or shed. That method is not wrong for its era, but it is not safer, and here is the honest reason why.

Every time equipment is disconnected and reconnected, you introduce wear and new risk — cross-threaded fittings, stripped unions, cracked plastic from handling, fresh leak points, and the classic missing or mismatched part come spring. Taking it apart does not remove the freeze risk; it just trades it for handling risk.

Modern pool equipment is designed to spend the winter right where it sits. Draining it through its own drain plugs and clearing the lines protects it every bit as well as a full teardown — with far less to go wrong. Less handling means fewer failure points, a cleaner and faster spring opening, and your automation and valve settings stay exactly where they belong.

The Simple Science of Freeze Protection

Freeze damage happens for one reason: water gets trapped somewhere, freezes, and expands with enough force to split pipes and crack equipment. Our closing removes trapped water four different ways:

  • Compressed air and line plugs clear and seal the plumbing
  • Antifreeze backs up the lines against any residual moisture
  • Open drain plugs empty the pump, filter, and heater
  • Gravity drains everything above the waterline back into the pool

No trapped water means nothing to freeze — and nothing to crack.

We Stand Behind Every Closing

Here is the part that matters most: we take full responsibility for the winterization we perform. Freeze damage is unmistakable and easy to diagnose — if we open your pool in the spring and find something that failed because of how we closed it, we own it and we make it right. That is our commitment to you.

You do not have to be an expert in every valve and plug. You just have to know that the people closing your pool do this hundreds of times a season, use a proven modern method, and stand behind the results. Trust the process — and hold us to it.

Old-School Teardown vs. The Credible Method

  Old-School Teardown The Credible Method
Freeze protection Yes Yes
Added wear every year High — constant disconnect/reconnect Minimal
New leak points & lost parts Common Rare
Automation & valves stay set No — reconfigured each spring Yes
Spring opening Slower, more surprises Faster, cleaner
