⚠️ Common Signs of Failure

• Cracks or crazing in the outer cover, especially at the bends
• Inner wall collapsing and starving the exchanger of flow
• Rubber flakes or debris found in the heat exchanger

🛠️ Service Notes

• Renew the hose clamps with the hose, as used clamps rarely re-seal on a raw water joint
