How To Fix Pool Filter Pressure Still High After Backwash
1. Inspect The Return Valves
When the pool filter pressure is too high, you need to start with the information in front of you.
The main reason this happens is when the water does not have a way to return. This starts to increase the amount of pressure that is being provided by the pressure gauge reading.
You will want to make sure the pool is in good shape and that is going to include looking at the return valves.
This is the only way you are going to have enough information to see what is wrong with the pool filter and whether or not it has to do with the return valves not working properly.
In most cases, the return valves are not going to be in good shape and that is what will get in the way of what you are doing.
2. Unclog The Return Valves
You will want to take the time to see where the clogged debris is in the return valve.
You will notice the water is not coming through the return valves and it is starting to rise in pressure. This is normal due to the obstruction in the valves.
The best option is to see how it can be unclogged.
You will need to assess the location of the debris and then begin clearing it out. This can be done by taking off the return valves and then seeing what can be done to remove the debris.
Each situation is going to be unique but it is a must when you want to do things properly.
3. Assess If The Pool Filter Is Working
You will also want to look at the pool filter.
Is it in good shape?
Are the settings working as they are supposed to? Sometimes, you are not going to get power to go to the pool filter, which is going to cause it to stop working properly.
This is going to depend on the type of pool filter you are using for the setup.
It is important to look into this when it comes to backwashing the pool. Getting as much information about the swimming pool is a must to guarantee good results as time goes on.
Otherwise, the pressure might come down but the water quality is going to remain poor.
4. Replace The Return Valves If Damaged
You will want to also think about whether or not the return valves in the pool are damaged.
In some cases, the return valves are going to get damaged and that will be the issue you are dealing with.
It is essential to think about what can be done to get the return valves back to how they need to be. If you are not taking the time to do this, the debris will remain in there and the return valves will not do their damage even when things are cleared up.
This is why you have to be diligent and continue to assess what is happening inside the return valves.
These are the details to consider if the pool filter pressure is still high after backwash.
If the pool filter pressure is still high after backwash, this means the return valves are either clogged or damaged. To fix the issue, inspect the return valves, unclog them, and then re-check the pool filter. If the return valves are damaged, it is best to replace them.
You will need to troubleshoot this problem and make sure you are taking the time to assess every inch of the return valves.
This is the only way you are going to be sure the problem is going to go away in the swimming pool.
