Quick overview
- Waterway part 425-1928 The factory waste outlet fitting, not a generic hose barb.
- Waste port only This is the fitting at the waste outlet, separate from the valve body it threads into.
- Sand filter service part Listed under Waterway Clearwater and Carefree sand filter parts.
- Common leak point The waste outlet takes the full backwash flow, so a cracked or worn fitting shows up as a drip every time you backwash.
- Direct replacement Goes in where the original fitting came out.
- Worth doing with a fresh o-ring Any sealing o-ring or gasket on the joint is cheap to renew while the fitting is off.

Product details
The Waterway 425-1928 is the waste outlet fitting used on Waterway sand filter assemblies. It is the factory part, listed under both the Clearwater top mount and the Carefree filter parts breakdowns.
Where it sits
The waste outlet is the port that dumps water out of the system when the valve is set to backwash or to waste. It carries the full flow of the pump every time you clean the sand, which is why the fitting itself wears and eventually weeps at the joint.
Before you order
This is the fitting alone, not the valve. If the leak is coming from the valve body or from the spider gasket inside it, those are separate parts. While the fitting is out, renew any o-ring or gasket at the joint so you are not back at the same drip in a season.
