Frequently Asked Questions

• Can I buy a replacement blue silicone valve for the MACVALVE?
  No, the plastic body is solvent welded and the blue silicone valve cannot be accessed or removed.
• Can MacValve or a non-return valve be used in line with macerator units (e.g Saniflo)?
  No. Some Saniflo unit installation instructions state that MacValve or Non-return valves can be used in conjunction with the unit, however, our products cannot accept the 10 Psi pressure from these units and are therefore not suitable for use. We suggest you contact Saniflo, or the macerator manufacturer, to discuss alternative options.
• Can a MACVALVE accept discharge from a domestic appliance?
  No, the water pressure from domestic appliances is too high for the self-closing valve to function properly, and a MACVALVE should never be used in this circumstance.
