Spec:
1. Hold the valve stem still with pliers. To protect the valve stem from damage, you can cover it with a cloth or a rag and let the pliers grip through the cloth.
2. Unscrew the old handle from the valve stem with your other hand.
3. With the pliers still keeping the valve stem still, thread the new handle in place.
4:It’s important to prevent any damage to the valve stem’s surface. Scratches and bumps may prevent the valve stem from sliding properly into the sealing gland inside the waste valve. Valve stem scratches may also damage the sealing gland.
