How Often should you clean your Tinaco

By Ivania Ramos, Vice President of Property Management with Galvan Real Estate and Services

The recommended frequency for cleaning your tinaco (rooftop water tank) in Mexico is every 6 months, or twice a year. This is the general guideline from the Mexican governments Secretaría de Salud.

This helps prevent sediment buildup, algae, bacteria, sarro (scale/mineral deposits), and potential health risks like gastrointestinal issues from contaminated water.

When to clean more frequently?

Every 3 months — If your water supply is low quality, highly mineralized (common in many Mexican regions with hard water), or if the tinaco lacks a proper lid/is exposed.

Every 4 months — In hot or tropical climates where algae and bacteria grow faster.

Rotoplas who is the largest Tinaco manufacturer in Mexico suggest up to 3 times a year depending on usage and materials.  The official advice is every 6 months for standard household conditions.

Quick tips for maintenance –

**Always ensure the lid is secure and in good condition to keep out dust, insects, and debris.

**During cleaning: Empty the tank, scrub with neutral soap/jabón neutro and a stiff brush, disinfect with diluted chlorine (cloro), rinse thoroughly, and refill.

**Consider periodic chlorination or algaecides (like pool floaters designed for tinacos) between full cleanings to control growth, especially with well water or in sunny areas.

If you have a cisterna (ground-level tank) too, it follows similar guidelines.

Regular cleaning keeps your water safe and extends the life of your plumbing. If your water comes from a questionable source or you see issues, error on the side of more frequent checks!
