Your on demand hot water system should not require any maintenance unless specified by the manufacturer. You may wish to operate the system pump regularly to ensure that it is in proper working order. Some parts may wear out over time and require replacement. Consult your instruction manual or dealer representative for further information.
Repairs to on demand hot water systems generally fall into four categories:
- Pump repairs
- Electric repairs
- Leak repairs
- Plumbing repairs
As with any complex electrical or plumbing device, carefully read the instruction manual before attempting any repair. When in doubt, contact your dealer, a professional plumber, or an electrician.
If the pump in your on demand system fails you will probably need to return it to the manufacturer for repairs or replacement. Most manufacturers offer a limited warranty on their pump products. Contact your dealer for instructions.
If the pump stops working one possible cause is a problem with the electric supply to the pump. If you have experience testing and repairing electric supply problems you may attempt this repair yourself. When in doubt, contact a professional electrician.
