💡 What causes premature seal failure in residential plumbing fixtures?
- Installing mismatched polymer blends degrades fast around oxidizers or glycol coolants making upgrades much handier when you swap to pure EPDM compounds
- Ignoring working pressure limits allows fluid to force past mating surfaces during pump cycling or sudden temperature shifts
- Storing loose inventory near direct sunlight triggers premature surface cracking before you ever mount them onto faucets or valves
