If your pool has Waterway Sand filter it goes without saying that the sand should stay in the filter. If you see it blowing out into the pool, something is broken. The most common problem is a cracked lateral, which is one of the perforated pipes at the bottom of the filter tank that catches water that has circulated through the sand. Laterals are proprietary , meaning you will need the exact “brand” to replace. Laterals also come in different styles too. Some Waterway laterals are “thread in” and some are “twist lock” Most Waterway laterals changed to “twist lock” in 2004. We are describing the method in which they connect into the manifold at the bottom of the “stand pipe”
Waterway Carefree sand filters (16” and 19” diameter tanks) and all Waterway Clearwater tanks (16”, 19”, 22”, and 26”) use 505-1930 Thread style or 505-1950 twist lock. The color of the part is not important, just to make it more complicated both styles have the same part number engraved into it. It is very clear which one is needed when you remove the old one.
