How to Troubleshoot Your Pool Overflowing After Rain

Hey there, fellow pool aficionado! Let's dive into a wet topic that might have you feeling a bit overwhelmed – handling an overflowing pool after a good ol' rain shower. As your pool-savvy best friend, I'm here to guide you through this soggy situation. So, grab your pool skimmer and let's get to work!

What Happens When a Pool Overflows from Rain?

You might think that a bit of extra water isn't such a big deal, but when rainwater gets into the mix, things can take a turn for the worse. Here's why:

1. Filter System Vulnerability

Even if water isn't pouring over the sides, having it above the optimal level can be problematic. When water surpasses the midpoint of your skimmer opening, your filtration system can struggle to do its job. Debris like leaves and bugs can't be effectively skimmed off, leading to a dirty, murky pool.

Pro Tip: If your pool's water level is only slightly higher than usual, give it a few days to evaporate naturally before taking action.

2. Altered Pool Chemistry

Rainwater isn't your pool water's BFF. It's acidic, which can throw your pool's pH levels out of whack. This not only affects sanitation but can also lead to unsightly stains. Plus, rainwater lacks the chemicals needed to maintain clear water. It's a bit of a party for contaminants, and they feast on your chlorine, leaving your pool's water quality compromised.

3. Surrounding Area Flooding

Overflowing water needs somewhere to go, and that's often your pool deck and surrounding yard. This flooding can destroy your landscaping and create a perfect breeding ground for pesky insects like mosquitoes. If not properly managed, excess moisture can even make your pool shell pop out of the ground – a "pool popping" nightmare.

4. Pool Structural Damage

Believe it or not, too much water can be bad news for your pool. Inground pools at capacity risk water seeping between the wall and vinyl liner, leading to sinking. Above-ground pools face structural stress, potentially causing wall and frame damage. Even your pool equipment isn't safe – flooding can spell trouble for your pump and more.

Draining a Rain-Overflowed Pool

When your pool is feeling a little too full, it's time to channel your inner pool pro. Here are ways to bring your water levels back to equilibrium:

  • Garden Hose Drainage Method: The simple yet effective siphoning method – just connect the hose to your tap and let physics do the work.

  • Utilizing Drainage Spigot for Drainage: If your pool setup allows it, attach a hose spigot directly to your plumbing for a straightforward drain.


  • Submersible Pool Pump for Effective Drainage: When the rain has been particularly generous and your pool resembles more of a water park than a serene oasis, it's time to bring out the big guns – the submersible pool pump. This heavy-duty equipment is your go-to solution for efficiently draining larger volumes of water from your pool after a heavy rain

Why Opt for a Submersible Pool Pump?

Unlike some other methods that may require manual effort or limited capacity, a submersible pool pump is designed to handle significant amounts of water. Its submersible nature means it can be placed directly underwater, making it incredibly effective at removing excess water without putting additional strain on your pool's structure or equipment.

Steps After Draining Your Pool

Just getting rid of the excess water isn't the end of the journey. To restore your pool's harmony, follow these steps:

  • Preventing Pool Overflow Incidents: Give your pool a shock treatment to obliterate contaminants, then test to gauge chemical levels.
  • Rebalance: Adjust chemicals as needed to bring your pool water back to its pristine state.

Preventing Pool Overflow Incidents

Prevention is key, my friend. Here's how to keep rainwater from becoming a pool party crasher:

  • Optimal Use of Pool Covers: Pull out that cover for heavy or extended rain periods. The right cover can work wonders in keeping your pool in check.
  • Installing Effective Drainage Systems: Proper drainage can work wonders. It'll keep excess water away and protect your pool area from flooding.
  • Proactive Pre-Draining Strategy: If you see a storm coming, consider preemptively lowering your pool's water level to make room for rainwater.
