When Pool Drains and Lines Get Clogged
Your pool pulls water through the main drain and skimmers before sending it to the pump and filter. Leaves, small toys, pebbles, hair and other debris can work their way into these lines and slowly block them. As flow drops, the pump strains, the skimmers stop pulling well and the water does not circulate properly.
Clogs often show up after storms, after a pool has been neglected or when skimmer baskets have been missing or damaged. Clearing the blockage restores healthy circulation and takes stress off your equipment. Good circulation also spreads sanitizer evenly through the pool, which helps prevent cloudy areas and algae in corners and on steps.
Signs of a Clogged Line
Watch for these common warning signs:
- Weak suction at one or more skimmers
- Low flow at the return jets
- A pump that runs loudly or struggles to keep prime
- An empty or half full pump basket while the pool is dirty
- Debris collecting near the main drain
- Filter pressure that is unusually low
How We Clear Pool Drains
We start by checking the pump basket, skimmer baskets and valves to find which line is affected. Then we use methods suited to pool plumbing to dislodge the blockage and flush it out, and we check flow afterward to confirm the line is clear.
While working on the drains we also look at the drain covers. Covers wear out over time and should be in good condition and properly secured for safety. If we find a cracked, loose or outdated cover, we let you know. With 20 years of experience, we treat drain work carefully and keep safety in mind at every step.
Pool Drain Questions
What usually causes a clogged pool line?
Leaves, small debris, toys and hair are the most common causes, especially when skimmer baskets are damaged or missing.
Can a clogged line damage my pump?
Yes. A pump that cannot pull enough water can overheat and wear out faster, so clogs should be cleared promptly.
