How long should a Diaphragm Pump last before needing a rebuild kit? The quick answer is a full season. Keep in mind that the time frame may vary depending on the amount of time it's used and the type of chemicals that are sprayed.
If your pump needs to be rebuilt every 3 months, you may have an intake restriction issue. To illustrate what an intake restriction will do to your pump, try drinking though a coffee straw at the same rate as you would a regular soda straw. The feeling you get in your head as your tongue gets vacuumed to the roof of your mouth is the same stress your pump endures when the intake line is restricted. If you continue to drink though the small coffee straw at a consistent rate, eventually you will develop a headache or maybe even pass out. Either way, you will STOP.
