Paddock VGB Drain Cover Lifespan
1. Recommendation: Check covers and screws yearly. Replace any covers or screws immediately that are compromised, damaged or broken in any way.
2. Requirement: Replace screws every 7 years at minimum (use only the size and grade of stainless steel screws 8/32 x ½ inch SS 316L recommended by Paddock).
3. Requirement: Inspect cover at 10 years minimum for any signs of damage and replace if needed. (Covers older than 10 years must be inspected every year thereafter for any damage compromising unit which would necessitate replacement.)
4. VGB Covers do not need to be replaced unless they are compromised, damaged or broken and all above requirements are met. These are stainless steel covers and should last life of facility if properly maintained. Ultraviolet light test is for degradation of resin products such as PVC or plastics.
