05 May Common Pool Filter Malfunctions
At Aqua Pool, we specialize in keeping your pool clean, beautiful, and running smoothly. That being said, there is a host of common pool filter malfunctions that even responsible pool owners face. Here’s a round up of the most frequent issues we see according to filter type. When it comes to sand, cartridge, and D.E. filters, we see a variety of smaller issues leading up to catastrophic problems:
- Bad Sand
After much use, the edges of sand can dull which results in less effective filtering and can lead to cloudy water.
- Broken Laterals
If you notice sand in your pool, you could have a cracked or broken lateral (small pipe in bottom of tank that water is pushed through).
- Leaking or Failing Valves
Inside a sand filter, an internal gasket channels your water return through the correct port. After much use, the inside valve can start to leak or rupture even causing malfunction and the need of professional attention.
- Oily Cartridges or Short Filter Cycles
These two symptoms are attributed to the need for either more frequent cleanings or replacement of your current cartridges.
- Popped Tops
A filter tank when put under pressure that has a misaligned clamp can pop the top resulting in a massive exiting water flow.
- Dirt in Water
If you notice that dirt seems to make its way around your filter cartridge, make sure that your cartridge is securely in position without allowing a gap at the bottom. This is an easy fix but one we see frequently.
- Calcium Clogging
E. filters can accumulate a mineral clog that slowly pushes filter pressure upwards. Address your filter grid fabric with a mild acidic solution to dissolve this build-up and reintroduce a healthy flow rate.
- Leaking Drain Valve
Most D.E. filters use a threaded cap and o-ring. It is important not to over tighten this connection to prevent cracking and possible leaking.
Oftentimes stainless steel tanks can develop tiny holes over time. These small pinhole leaks require professional attention to prevent further issues and leakage.
