Symptoms
- Pump feels loose or doesn't build resistance
- Little to no output despite pumping or pressing
- Leaking from the seal during use
Likely causes
- CommonWorn or dirty sealSeals wear down over repeated use and can lose their airtight fit.
- CommonValve stuck or clogged with residueBuildup from regular use can prevent a valve from sealing properly.
- CommonParts not assembled correctlyMissing a small gasket or seating a part slightly off can prevent pressure buildup.
- Less commonCracked housingA small crack can leak pressure even if not visibly obvious.
What to do
- Disassemble the device following the manual and check all seals and gaskets are present and undamaged.
- Clean all parts thoroughly, especially valve components, to remove residue buildup.
- Reassemble carefully, making sure each part is fully seated before use.
- Check for any small cracks in the housing by looking closely or feeling for air escaping.
- Test with a spare seal or gasket if one is included with the product.
- Contact the manufacturer for replacement seals, which are often sold separately.
- Replace the unit if pressure loss continues despite clean, correctly assembled parts.
