Pool Sand Filter Leaks & Why They Happen

Pool Sand Filter Leaks & Why They Happen

Your pool sand filter is important for keeping your water clean and fresh. As water pumps through the filter, the sand helps trap debris and dirt.

However, if your sand filter is acting up, then you could end up with a dirty pool. And unfortunately, this is one of the most common issues pool owners face.

So let’s talk about some common sand filter problems and how you can resolve them. That way, you and your loved ones can get back to enjoying the pool sooner rather than later.

Pool Sand Filter Leaking From Top? Potential Reasons

Cracked Tank

A sand filter is a pressurized device. If the tank has a crack in it, it will need to be replaced.

Low Or High Filter Pressure

The ideal sand filter pressure is somewhere between 10 and 25 psi. If the system has an obstruction somewhere or incorrect sand levels, then it can inappropriately decrease or increase the pressure.

For instance, if the pressure goes below 10 psi, you might have a clog. You should clean out the pool skimmer and then inspect the pump.

However, if the pump doesn’t have any issues, then it could be low pool water levels or a lack of sand in the filter itself. Either way, you should reach out to professionals for maintenance and inspection.

Broken Multiport Valve Handle

If the multiport valve handle is loose or broken, various ports and pathways can be affected. This could alter the backwash, filter, rinse, water, and closed settings.

Leaking Waste Line

A damaged spider gasket could cause a leaking waste line, which could lead to a host of other issues.

The Importance Of Getting Your Filter Replaced

Health And Safety

If you don’t replace your sand filter in time, you could deal with several problems with your pool safety.

Debris, bacteria, and grime can build up in the pool. This can occur from animals, people, sun lotions, and several other sources. Even rainfall, pollen, leaves and twigs can create a dirty pool.

This creates a breeding ground for disease and bacteria. Ultimately, this can cause skin irritation, eye irritation, and even respiratory problems.


Nobody wants an ugly pool. Keep your pool clean and clear. You can feel proud inviting anybody over to enjoy it.


It’ll be more expensive to have your pool completely cleaned out, drained, or repaired if you let the damage get too severe. It’s best to stay on top of these problems early and often.
