Depending on the type of filter, and the amount of cleaning, the process time could vary. If you have a sand filter, the chemicals will be added to the filter and the correct lines will be plugged. The chemicals will be soaked in the sand, and when complete, we will have the filter up and running again.
If you have a D.E. or cartridge filter, the filter will be disassembled and the inside assembly will be removed. Depending on the amount of cleaning needed, it will either receive a quick peroxide cleaning or will need to be soaked in a filter cleaning chemical over night. The next day the assembly will be power washed, and re-installed.
