#5: Check the Main Water Filter
If you’re not regularly cleaning your swimming pool’s main water filter every six months, that may be the cause of your pool’s low water pressure. When left uncleaned for long periods of time, your main water filter can become clogged. When it is clogged, the water pump is unable to work effectively, causing pressure to drop. At this point, your pool will be unable to keep up with the buildup of dirt and debris. Of the five DIY check-ups we’ve discussed so far, this one is the most involved, which is why we saved it for last. It can take a bit of time to clean the main water filter. You have to remove the cover, remove both the inner and outer filters, clean each element of those filters, and then clean out the filter housing bottom as well. However, if you’ve checked all the other components we discussed and your pool still has low water pressure, it’s time to check the main water filter.
Sometimes even that is not enough though. Let’s talk now about when you need professional help.
