O-Ring Wrekin HD10 Blue Bowl - Heavy Duty Housing Replacement O-Ring 10028034

This O-ring from WrekinWater, part number 10028034, is the replacement seal for the Wrekin HD10 heavy duty filter housing with the blue bowl, sealing the bowl against the housing head under mains pressure.

Signs this seal needs replacing

• Weeping or dripping from the join between the blue bowl and the head.
• The old O-ring appearing flattened, cracked, or sticky.
• Needing extra force on the bowl spanner to stop a leak.
• A drop in pressure after the housing has been opened for a filter change.

On the HD10 heavy duty housing, this O-ring is what allows the blue bowl to seal against the head under the higher pressures these units are built for. Rubber seals lose their elasticity with age and repeated compression, and once that happens even a housing that's tightened correctly can weep at the joint.

WrekinWater specifically notes this O-ring fits the blue bowl HD10 only, helping you avoid ordering the wrong seal, and stocks it as part of 15 years' experience supplying Wrekin heavy duty housing parts from Shropshire.

How to replace it

1. Turn off the water supply and open a tap to release pressure in the housing.
2. Unscrew the blue bowl from the housing head using the housing spanner.
3. Remove the old O-ring 10028034 from the head groove.
4. Clean the groove and lightly grease the new O-ring with food-safe silicone grease.
5. Fit the new O-ring and screw the bowl back on hand-tight plus a small turn.
6. Restore the water supply and check the joint for leaks.
