I'm often asked if I provide bi-weekly service, or if I come less in the winter for a lower rate and my answer is always no. When you have been around pools as long as I have, you know better.
Arizona Monsoon season is July-September. However, wind storms and rain storms are not limited to these months alone. In the example illustrated on the left, there were city owned trees next to the property on the other side of a retaining wall. I had to take a picture of the amount of plant debris I pulled out of the strainer basket, because it was as full as it could possible be after a storm...in January.
Baskets that are full of debris restrict water flow, which in turn does not cool the motor, or filter enough water from the pool. Excessive heat can cause a lot of unwanted and expensive problems, which can easily be avoided with weekly maintenance.
Through out the year, I find dead birds, rodents and even reptiles getting into the skimmer. In the image to the right, I found a small rabbit stuck in the intake of this Vac-Mate. The rabbit was starting to decay and had plugged the intake hole. The water flow was restricted, the pump was running hot and there was no filter pressure.
