Questions and answers
I have a leak on the primary filter chamber i have replaced the o rings and it still leaks. Can you tell me what i can do to fix this problem
To fix a leak in the primary filter chamber of a Davey RainBank Evolution MkII after replacing the O-rings, follow these steps:
1. Ensure the O-rings are the correct size and type for the unit.
2. Check that the O-rings are seated properly and not twisted or damaged.
3. Apply a suitable lubricant (not petroleum-based) to the O-rings to help them seal better.
4. Make sure all connections are tightened securely but not overtightened.
5. Inspect for any debris or damage on the sealing surfaces that could prevent a proper seal.
6. If the leak persists, reassemble the unit and ensure all parts are aligned correctly.
Always disconnect the power supply and relieve pressure before performing maintenance.
