Pool pump and filter in Tulum: how to know when they're failing

A pool filter needs backwashing when pressure rises 3 to 5 psi above its clean start-up reading. If pressure doesn't drop after backwashing, the filter media is exhausted or channeling and has to be replaced — something that in Tulum happens every 12 to 36 months depending on the area.

How to read the pressure gauge

Situation	Diagnosis	Action
Clean start-up pressure	Normal	Write it down: it's your baseline
+3 to 5 psi	Dirty filter	Backwash
High and won't drop after backwashing	Media compacted or channeling	Replace the filter media
Low with the pump running	Insufficient flow: obstruction or air	Check basket, trap and suction
Needle oscillating	Air in the system	Check lid, o-ring and water level

How often the filter media is replaced in Tulum

Manuals say 3 to 5 years. In Tulum that almost never applies, and it varies a lot by area:

Area	Local factor	Media life
Soliman Bay, Tankah	Fine beach sand that compacts	12 – 18 months
La Veleta, Región 12	Construction dust	18 – 24 months
Holistika, Macario Gómez	Jungle organic matter	24 – 30 months
Town colonias	Lime from the well water	24 – 36 months

Signs the pump is about to fail

Metallic noise or squeal on start-up: worn bearing. Cheap to replace now, expensive later.
Motor very hot to the touch: blocked ventilation or a strained winding.
Constant drip at the base: failed mechanical seal. Leave it and water gets into the motor and you lose it.
Loses prime and you have to fill the trap: air entering through suction or a badly sealed lid.
Rust on the housing (beach zone): salt-air corrosion; check the electrical connections immediately.

How many hours a day the pump should run

The general rule is that the full volume of the pool should pass through the filter at least twice a day. In Tulum, with high water temperature and a constant organic load, we work with 8 to 10 hours a day in the hot season, concentrated during sunlight, which is when algae have the best opportunity. Turning the pump off to save electricity costs more than the bill it saves.

Frequently asked questions

Frequently asked.

How often should a pool filter be backwashed?

When the gauge rises 3 to 5 psi above the start-up pressure with a clean filter. In Tulum that's usually every one or two weeks in the hot season, and more often if there's construction nearby or the pool sits under trees.

How long does the sand in a pool filter last in Tulum?

Between 12 and 36 months depending on the area, quite a bit less than the manual's 3 to 5 years. On the coast, fine beach sand compacts the media in 12 to 18 months; in town, lime from the well water exhausts it in 24 to 36.

How many hours a day should the pump run?

Between 8 and 10 hours in the hot season, enough for the full volume to pass through the filter at least twice. It's worth concentrating them during sunlight hours, which is when algae have the greatest opportunity to grow.
