No routine or seasonal maintenance is required for the HepvO sanitary waste valve, however, should you blow-out your drainage lines do not exceed 80-100 psi.
- HepvO is resistant to standard caustic-based drain cleaners. It is also resistant to acid-based cleaners with concentrations up to 10%. When flushing with higher concentrations of acid based cleaner, the valve must be removed before the operation.
- If mechanical drain cleaning devices are to be used it is necessary to first remove HepvO from the waste system. This provides a useful access point for servicing downstream pipework.
- It is good practice to rinse the HepvO valve with clean water after any maintenance procedure.
