Safety and a Quick Inspection First
It is wise to put off pool cleaning for a moment after a bout of heavy rain or high winds. Make an initial sweep of the patio and pool area for any hazards before you begin:
- Check for tripped breakers, damaged outlets or downed power lines
- Be on the lookout for loose decking, broken glass and other storm debris
- Note any floodwater near the equipment or signs of electrical trouble
Should you come across structural damage, electrical faults or flooding by the pump, have everyone stand clear and put in a call to a utility or a qualified pool pro. Under no circumstances should one swim if the water or system is not verified as safe.
When it is time to open the skimmer or pump strainer, the pump must be off. Adhere to the instructions in your manual and chemical labels, and don’t forget to put on proper PPE like gloves and closed-toe shoes.
Tackle the Debris Before Vacuuming
The most effective way to clean up is to get rid of what is floating on top before addressing the grit below. Begin with the larger leaves and branches to prevent clogging your filters.
- A leaf rake or net will do for the surface of the pool
- Pick up any sticks or twigs from the steps and shallow ledges
- Make sure the pool area and adjacent drains are clear
Take your time with this; agitating too much organic matter can cloud the water and only prolong the job. If the cover has been holding debris, take it off with care so the leaves do not drop back in.
Skimmers, Baskets and the Waterline
With the surface largely cleared out, it is time to empty the baskets in the skimmer and pump.
- Shut down the pump prior to any access
- Rinse the basket if it is full of leaves or grit
- Give the pump strainer a once-over for anything that might impede flow
- Wipe away residue from the waterline
If you encounter a lid that is stuck or a part that is cracked, do not try to force it. The same goes for a pump motor that is sounding strained; at that point, contact a service professional.
Dealing with Fine Sediment on the Floor
Even when the pool appears in order, storm grit will have made its way to the bottom and can leave the water hazy.
- A light brushing will dislodge material from the corners and steps
- Vacuum at a leisurely pace to avoid churning sediment back into the water
- Be diligent in emptying robot filters or cleaner canisters
For a pool that has taken a beating from the storm, you may find manual vacuuming preferable to putting a cleaner to work right away.
Filtration and Water Balance
Run the pump as the manual dictates and give the filter a good look.
- Any poor water flow or odd pressure should be noted
- Backwash or clean the filter in keeping with the manufacturer’s guidance
- Test to see if the storm has altered the chemistry or diluted the chlorine and make adjustments
- Top off the water level if the rain left it low
Some pool owners make the error of using shock without ensuring the water is clear for circulation, or they ignore a clog. Avoid these pitfalls and never enter a pool where the water quality is in question.
When to Put in a Call for Service
There are times when a pool owner is better off leaving it to the experts. Seek professional help if the pool remains cloudy despite your efforts, or if there is reason to believe floodwater has contaminated it. Leaks, air in the system, damaged valves or electrical problems are all cause for concern.
A pro can spot hidden damage from severe weather and get the water clarity back to where it should be. For the most part, the prudent course is to follow the proper sequence of removing debris and looking after the pump and filter, rather than taking any shortcuts.
