Clogged Pool Lines? Here's a Step-by-Step Guide to DIY Unclogging
Is your pool pump working overtime but the water pressure seems weak? Do you hear loud noises coming from the equipment but can't get the water flowing right? It's likely you have a blocked pool line preventing proper circulation.
Pool plumbing clogs can happen over time as debris builds up. Leaves, dirt, algae, and scale slowly accumulate inside the pipes, reducing the water flow. Fixing a clogged pool line is possible on your own without calling a professional - if you follow the right steps.
Detecting a Clogged Pool Line
How can you confirm it's actually a blocked pipe causing issues before attempting to unclog it? Here are signs of a clogged pool line:
- Reduced water pressure - Pool takes longer to fill
- Loud or pulsing pump noises
- Pump working hard with little results
- Cloudy water circulation
Before assuming it's a clogged line, rule out other potential problems first. Check that the pool water level is normal, skimmer baskets aren't overflowing with debris, and there are no air leaks or issues with the filter. If those are all clear, it likely means there is a blockage in the plumbing.
Finding the Blocked Line
Most pools have multiple plumbing lines - one for the main drain, skimmers, jets, etc. To pinpoint which one is clogged, you'll need to isolate and test each line separately.
Start by turning on the pump and closing all the pool valves except one line. Check the pressure gauge on the filter while running water through only that line. Repeat this for each line, comparing the pressure readings. The pipe with the lowest pressure is likely where the clog is occurring.
This may take some time, but it's the only way to identify the specific blocked line without having to clear every single one. Once you've confirmed the clogged pipe, turn off the pump and get ready to tackle the blockage.
Step-by-Step Guide to Unclogging a Pool Line
Unclogging a pool line is a straightforward DIY project if you have the right tools and follow safe procedures.
Safety first! Before attempting to clear any clogs, turn off the power to the pool pump. This avoids injury from the moving parts inside. Next, close all the pool valves except for the line you identified as blocked. This focuses the pressure only on the clogged pipe when you begin blasting water through it.
2. Attach Hose Jet to Pipe Opening
A hose jet (also called a bladder) is designed to seal over the opening of the pool pipe. Attach this securely with the hose connected. Be sure it creates a tight seal so maximum pressure goes through the line when turned on.
3. Blast Water Backwards Through Pipe
With the hose jet sealed in place, turn on the water! This will send a strong stream backwards through the pipe, dislodging any built-up debris. Let it run for several minutes until the pressure gauge shows normal readings again. Using this backflow method forces out even stubborn clogs.
4. Increase Pressure With Tennis Ball
For severe clogs, hold a tennis ball over the skimmer opening while blasting the hose. This increases the backpressure for a more powerful cleaning effect. Check the pressure gauge - when it returns to normal, the line should be cleared.
5. Consider a Professional CO2 Cleaning
DIY unclogging methods may not work on lengthy or very obstructed pipes. Call a pool service company to use a CO2 system - it delivers highly pressurized bursts of carbon dioxide to break up the toughest blockages.
Preventing Future Pool Line Clogs
Regular maintenance helps avoid a recurring clogged line problem. Here are some tips to keep your pool plumbing clear:
- Clean out pump baskets and skimmer daily
- Monitor water chemistry/pH to control algae and scale
- Inspect all plumbing openings for debris buildup
- Consider professional servicing to routinely clean the pipes
Advanced cleaning methods like hydro-jetting can also be used quarterly to keep interior pipe surfaces debris-free. Taking preventive steps will save you time and money in the long run.
When to Call a Pool Service Company
In most cases, a DIY unclogging resolves the issue. But if you still have low pressure after trying all troubleshooting steps, contact a pool professional for assistance.
A technician can use specialized power equipment like industrial CO2 systems or hydro-jet blasters. For severely damaged lines, pipe replacement may be required. Leaking joints may also need resealing.
Technicians can also inspect the overall plumbing system to get to the root of what's causing repeated clogging. Whether it's pipe layout, missing strainer baskets, or lack of maintenance - they can advise on upgrades or process changes to stop future problems.
FAQs about Unclogging Pool Plumbing
What causes clogged pool lines?
Debris like leaves, dirt, and sand gradually build up inside pool plumbing over time. Calcium/scale deposits from unbalanced water chemistry can also block pipes. Algae and biofilm growth are other common clogging culprits.
Which pool lines clog most often?
The skimmer and main drain lines tend to clog more frequently than return lines. That's because they pull in debris from the water surface and bottom of the pool.
Can I use a drain snake to unclog pool pipes?
You can attempt using a drain snake for removing stubborn clogs. Feed the rotating wire down the pipe to break up and dislodge debris. Take care not to damage PVC pipes - a hose jet is lower risk.
When should I call a professional vs. DIY?
You can try DIY methods like hose jets for regular clogs. But for chronic issues or pipes deeper than 2 feet, call a pro for hydrojetting, CO2 cleaning, or potential pipe replacement.
How can I prevent my pool lines from clogging in the future?
Stay vigilant about cleaning baskets, balancing chemicals, and inspecting plumbing openings for debris buildup. Consider professional maintenance services to routinely clear pipes before major blockages occur.
Dealing with reduced water pressure and circulation issues from a clogged pool line can be frustrating. But in most standard cases, it's possible to successfully unclog the pipes yourself.
Follow our step-by-step guide to safely locate and clear out the blockage. Restoring normal water flow prevents expensive equipment damage down the line.
With some preventative maintenance, you can avoid plumbing problems. Dive in and enjoy your sparkling, flowing pool again!
