Unfortunately, if the pressure in your pool pump drops or increases dramatically, it can indicate that something is wrong with the pump or another issue. Wondering what you need to know? Take a look at these tips:
1. Know how to check the pressure on your pool pump.
Most pool pumps feature a gauge that indicates the internal pressure of the pump. When you buy a new pool pump, make sure that you know which pressure the pump runs at in ideal conditions. Then, teach yourself how to read the gauge so that you can tell if it is high or low.
2. Troubleshoot low pressure by cleaning the filter.
If the pressure on the gauges reads lower than it should, the pump may not be able to pass through enough water due to the blocked filter. Luckily, it's easy to remedy. Simply take the filter out of the pump, wash it off with a hose and replace it. Mind the fact that, sometimes, debris gets caught in the crevices and pleats of the filter so make sure those areas are clear.
3. Address high pressure by checking the air breather tube.
Pool pumps have an air breather tube that allows trapped air to exit from the pump. If the air is stuck due to a clogged tube, pressure can build up under the dome of the pump. In some cases, the breather tube is located under the manifold assembly and leads into the discharge line. In other cases, the tube is under the dome of the pump, and it runs to the base of the pump.
If your gauge reads high pressure, turn off the pump. Carefully open it and find the air breather tube. Gently depress the tube with your fingers to see if you can feel a clog. If so, detach the tube from both sides run water through it until the clog is gone.
4. Add water for fluctuating pressure.
If the pressure on your pool pump goes up and down, the issue may be with the level of water in your pool. Namely, if the water is low, air will be sucked into the pump. That can cause the pressure to fluctuate. Fill the pool so that it amply covers the opening of the filter. If adding water to the pool doesn't help, contact a professional. They can help you make sure the gauge on your pump is working correctly, and they can address issues as needed.
