Pool filter cartridges can run for about 2,000 hours for a filter pump. Usually filter cartridges have to be replaced once every 1 or 2 years. The life of the filter will be less if you enter the pool with suntan lotion, deodorants, mousse, styling gels, and other damaging chemicals.
Also, about every 10 years or more, youâll probably need to replace (or repair), much of your pool equipment â namely the pump, filter, cleaner or heater. Replacement value can be set for each equipment item, and amortized over a ten to fifteen year period to compute an annual pool equipment replacement cost.The average inground pool spends about $50-$500 per year on repair parts or replacement equipment.eplacement value can be set for each equipment item, and amortized over a ten to fifteen year period to compute an annual pool equipment replacement cost.
