Why is my filter pressure so high??
If you own a pool or spa, you must know how important a swimming pool filter is. A filter removes dirt, debris, and other contaminants, so that your water remains clean and sparkling. However, sometimes the pressure on the filter gauge gets too high, and you might wonder why. In this article, we'll take a look at ten potential prospects to this issue, and how to solve them.
1. Clogged or Dirty Filter
One of the most common reasons why the pressure in the filter rises is due to a clogged or dirty filter. If the filter cartridge is filled with debris and contaminants, it will have a harder time pushing water through, leading to higher pressure. To fix this, simply clean or replace the filter cartridge. Ideally, you should clean your filter every one to three months depending on usage.
2. Faulty Pressure Gauge
Another reason why your filter pressure might be high is due to a faulty pressure gauge. Sometimes, the gauge can be inaccurate or not calibrated properly, causing the reading to be higher or lower than the actual pressure. If you suspect this is the problem, you might consider getting a new gauge or calibrating it.
3. Air Leak
If there is an air leak in the system, it can also cause the filter pressure to rise. This could be due to loose fittings, cracked pipes, or faulty valves. When air enters the system, it takes up space and reduces the amount of water that can flow through, leading to higher pressure. You can try to locate the air leak and fix it, but if you can't, it's best to call in a professional.
4. Dirty Pump Basket
Similar to a clogged filter, a dirty pump basket can also cause high pressure in the filter. When the pump basket is full of debris, it restricts the flow of water, causing the filter to work harder. Make sure to regularly clean the pump basket by removing it and flushing out the debris.
5. Oversized Pump
If you have an oversized pump, it can also cause high filter pressure. This is because the pump is pushing too much water through the system, making it harder for the filter to keep up. If this is the case, you might consider downsizing the pump to a more appropriate size for your system.
6. Closed Valves
If you have accidentally closed one or more valves in your system, it can also cause high filter pressure. When a valve is closed, it restricts the flow of water, which causes the filter to work harder and raises the pressure. Make sure all valves are open and free of restrictions.
7. High Water Table
If you live in an area with a high water table, it can also cause high filter pressure. This is because the pressure of the groundwater can push water back into your pool, causing the filter to work harder. If this is the case, you might consider installing a check valve or an anti-siphon valve to prevent backflow.
8. Dirty Pool or Spa
If your pool or spa is extremely dirty, it can also cause high filter pressure. This is because the filter is working harder to remove the debris and contaminants in the water. Make sure to regularly clean your pool or spa to reduce the amount of debris that enters the filter.
9. Broken or Damaged Filter
If none of the above reasons seem to be the problem, it's possible that your filter itself is broken or damaged. This could be due to cracks or tears in the filter cartridge or damage to the filter housing. In this case, you might need to replace the filter entirely.
10. Incorrect Plumbing
If your plumbing is incorrect or outdated, it can also cause high filter pressure. This could be due to undersized pipes or improper fittings. If this is the case, you might consider remodeling your plumbing system to better suit your needs.
Conclusion
Overall, there are many potential reasons why the filter pressure in your pool or spa might be high. By systematically checking each prospect, you can identify and fix the problem, and ensure that your water remains clean and clear. Remember, regular maintenance and cleaning of your pool or spa filter can go a long way towards preventing issues like this from arising.
