Model # T240BP1
Is 20-40 the correct size of sand for the T- 240BP-1?
If T-240BP-1 sand filter is unavailable, what is the replacement sand filter, are all the dimensions the same and how much does it cost.?
When should I change the sand in my filter?
You should change the sand in your filter every 5-7 years. You can generally tell that it is time if your pool water is not as clear as it normally is or when you notice the interval between backwashes is shorter. You can use > this guide to walk you through it.
