How to Clear a Clogged Pool Line Drain Without Calling a Plumber

Pool Line Clogged? A clogged pool line drain can ruin an otherwise refreshing swim. When debris, scale buildup, or airlocks clog your pool's circulation, you may notice reduced water flow, gurgling noises, or air bubbles from the return jets. Left unchecked, these clogs can strain your pump and filtration system, resulting in costly repairs.

The good news? You do not have to call a plumber to fix it. With the correct tools and techniques, you can unclog your pool lines quickly and efficiently by yourself. This article will walk you through simple, practical methods for clearing a clogged pool line drain, keeping your swimming pool flowing smoothly, and preventing future blockages.

4 Common Causes of a Clogged Pool Line Drain

A clogged pool line can happen for a variety of causes, from common debris to more serious plumbing concerns. Identifying the reason of the blockage allows you to determine the most effective technique to clear it. Here are some of the most common causes:

  1. Debris Buildup

    - Leaves, debris, algae, and even tiny toys can get stuck in the skimmer or return lines, reducing water flow. This is one of the most common reasons of clogged pool lines, particularly in pools surrounded by trees.

  2. Calcium or scale deposits

    - Hard water can cause mineral buildup inside pipes, gradually narrowing the path and resulting in clogs. This is particularly common in locations with high calcium levels in the water.

  3. Airlocks

    - When air becomes trapped in your pool's plumbing, it can disrupt efficient water circulation.  This frequently occurs after faulty priming of the pump or during winterization, and might result in gurgling noises or insufficient suction.

  4. Collapsed or damaged pipes

    - If typical unclogging pool methods fail, the problem could be structural.  A damaged or collapsed pipe could be blocking water flow and requires professional inspection or repair.

Most clogs can be cleared quickly and effectively with a high-pressure drain flusher saving you money on plumbing repairs.

How to Unclog Pool Lines Using a Drain Flusher: Step-by-Step Guide

Cleaning a clogged pool line drain does not have to be difficult. With the proper drain flusher, you can quickly restore water flow and keep your pool running smoothly. Follow these instructions to unclog your pools without calling a plumber.

  1. Check and clean the skimmer basket

    • Before using any flushing method, make sure the skimmer and pump baskets are clear of debris. A clogged basket can reduce suction and make it appear like your pool lines are blocked.
    • Remove any leaves, dirt, or debris from the skimmer basket to ensure appropriate water intake.
    • Check the pump basket for any obstructions that may be preventing water flow.

  2. Flush the Pool Line with a Water

    • One of the most effective ways to remove a blocked pool line is to use a drain flusher attached to a garden hose.
    • Place the drain flusher in the skimmer or drain line fully and turn the water on full force quickly.
    • The expanding drain flusher locks into place generating water pressure with a powerful jet action to dislodge clogs and restore normal flow.

  3. Reverse Flush for Stubborn Clogs

    • If debris is trapped deep in the line, reversing the flow can help break it up and flush it out.
    • Insert the drain flusher completely at the opposite end of the clogged line (for example, the return jet or pump intake).
    • Turn the water on fully open and flush the obstruction in the other direction.
    • Continue until the water runs freely.

  4. Blow Out the Pool Lines to Remove Airlocks

    • Airlocks can mimic the symptoms of a clog. Using a drain flusher with powerful water jet action can help remove trapped air.
    • Install the drain flusher so it is all the way in the return or skimmer line.
    • Allow the pressured water to force air pockets and debris out of the system.

  5. Perform Seasonal Maintenance to Prevent Pool Line Clogs

    -
    • Regular flushing keeps pool lines clean and prevents build-up from becoming a larger problem.
    • Flush the pool lines at the beginning and conclusion of the swimming season.
    • Use the flusher on a regular basis to remove any debris that could cause a blockage.

Preventative Maintenance Tips to Keep Your Pool Line Drain Clog-Free

Keeping your pool's lines clean reduces the possibility of future clogs and costly repairs. A little routine maintenance goes a long way toward ensuring proper water circulation.

  • Clean skimmer and pump baskets regularly - To ensure strong suction, clean the skimmer and pump baskets on a regular basis.
  • Use a Professional Drain Flusher Seasonally - Flushing your pool lines multiple times per year helps to prevent buildup and blockages.
  • Maintain proper water chemistry - Balancing pH and chemical levels helps to prevent calcium and scale deposits in pipes.
  • Winterize pool lines correctly - If you live in a cold region, properly blowing out pool lines will keep them from freezing and cracking.
