If you are noticing some sand collecting in the pool, it may be a problem. The filters may have worn down, or some part of them may be broken. It is important to examine all of the components.

2. Damaged Backwash Valve

Your backwash valve may cause this problem. If there is a leak or some issue with the backwash valve, then the small amounts of sand might leak. This can be an easy fix as you just have to replace the O-ring for the valve. High filter pressure is something that the pool owners may across at some point.

It is not something to worry about as this keeps the filter pressure at 5-20 psi. If your pool sand filter pressure exceeds the recommended range, then your filter may end up bursting. This is why it is important to keep the filter maintained. High filter pressure can be due to dirty water. The sand particles catch algae and debris and this can be fixed easily by cleaning out your filter.

3. Air Leak

If the pressure in your sand filter is too high after you have cleaned it and backwashed it, then you may be dealing with an air leak in your filtration system or pump. This could be a problem but you can fix it yourself. If some bubbles are coming out of the strainer pot of your filter system, then it may be a sign of an air leak.

4. Low Filter Pressure

Low filter pressure is way less dangerous than high filter pressure but it can still cause issues. It is important to fix this problem and make your pool sand filter flow at an acceptable rate. The Clogged skimmer basket is one of the most common reasons for the lower filter pressure.

If the filter pressure is low when the pool pump is turned on, then you must check your skimmer basket. Clogging in the plumbing could be a reason for low filter pressure as well. You must take care of all the plumbing issues to clear any kind of blockages to fix this issue.
