Helpful Information


Low Water Pressures Perrin & Rowe kitchen taps are compatible with most low water pressure installations. To support water conservation regulations, Perrin & Rowe kitchen and basin taps are fitted with a flow controlling spout tip aerator. This limits the water output to 6 to 7.5 L/min to give a WELS Four Star rating. This flow rate is based on taps installed into homes with an incoming pressure of 150 to 500 kPa. When Perrin & Rowe kitchen and basin taps are installed into homes with low inlet water pressure of less than 150 kPa, we can change the spout tip aerator to a non-flow-controlled version to achieve the 6 to 7.5 L/min flow rate. Kitchen taps with a spray rinse require a minimum inlet water pressure of 100 kPa to activate their diverter mechanism and a maximum of 500kPa. The single lever shower mixers N5506, N5106 and N5806 require at least 100 kPa to operate their internal pressure balancing valve.


Ceramic disc cartridges incorporated within Perrin & Rowe tapware are a consumable item and have a parts replacement warranty for five (5) years from the date of purchase. The consumable component warranty provides for the supply of replacement cartridges during this period. Flexible hand shower and kitchen tap spray rinse hoses, O rings and washers, non-return valves, poppet valves and aerator inserts are also consumable components and covered by a five (5) year parts replacement warranty from the date of purchase. The warranty excludes damage caused by misuse, improper installation, or vandalism. Proof of purchase is required before service parts are sold or technical advice is given.


Tapware must be installed by a Licensed Plumber in accordance with the relevant Standards and plumbing regulations, the Perrin & Rowe installation instructions, and best trade practice. Warranty is voided by Failure to observe Perrin & Rowe’s manufacturer’s care and cleaning instructions.


Information regarding product care and maintenance of your product are reasily available. Warranties on Finish are voided by any of the following:
i. Damage to finishes by adhesives, sealants, paint, or any solvents used to remove them. Paints continue to cure for a few days. Vapours released during this process can sometimes cause metal finishes to discolour or tarnish. It is best to wait until no paint odour can be detected before installing tapware and accessories.
ii. Damage to finishes by use of unsuitable cleaning agents or improper materials contrary to the Perrin & Rowe manufacturer’s Care and Maintenance instructions. These include cleaning agents containing acidic, corrosive, abrasive, citrus, or alcohol-based substances or through scouring of a surface by abrasive cloths, sponge pads or similar.
iii. Damage to finishes which arises from installation or post-installation use.
