Sand Filter Lateral Replacements - Threaded Style
The lateral pipe is the major part of any sand filter used for a swimming pool and if broken or worn can have a negative effect on the quality of your pool water.
Sign of a broken or worn out lateral are :
- Sand on the pool floor
- Cloudy water
To replace the broken laterals you will have to empty the sand from the filter into a large container. To do this you need to remove the multipart valve carefully to not damage the O-rings. Cover the long pipe leading from the multipart valve inside the sand filter with a plastic bag and use an elastic band to hold the bag tight.
Remove the sand and then clean around the laterals. Once the laterals are clear of any sand, undo the broken lateral and replace with a new one.
When you have completed the above steps, refill with the sand you have saved. Remove the plastic bag from the manifold pipe and replace the multipart valve carefully and secure to the filter.
You will notice the pool water become cloudy but don't worry as this will clear after a short time.
