How to Care for Your Pool During/Post Rainfall

Some people will have clear pool water after a storm, some people will not. Regardless of the pools colouring after heavy rainfall it is important to check that your pool chemistry is still correct immediately to prevent damage.

**Rain is acidic and will lower your pH and alkalinity. If the pH drops too low, the water in your pool will become acidic (low pH generally makes the water really clear) which will cause damage to the pool equipment.

So, to start check the basics:

  • Check the chlorine, as well as the salt/mineral levels depending on the system you have. Even if you have a salt or mineral system, extra chlorine may be needed to prevent the levels dropping too low resulting in algae blooming.

  • Check all your electrical equipment for damage or puddling before turning the power back on.

It is highly likely it will not be just the rainfall you are dealing with but also the runoff from roofs, patios, gardens etc. which can/will add a variety of contaminants to your water chemistry.

Contaminants can also come from not monitoring your pool water levels. If the pool water level does start to overflow into your gardens, patios or grass areas it will bring other contaminants/bugs into the pool, and, flood your backyard.

If you have a waste or backwash line make sure you drain a little water off as the pool levels increase. It is equally important not to drop your pool level too low because it leaves the pool walls open to damage from debris, and, more importantly, the weight of existing water will prevent it from lifting out of the ground due to excessive moisture the soil will swell.

If you are unsure of what your levels should be, or on any of the steps to take post downpour, make sure to contact your local dealer as soon as possible.
