12 months after fitting an Oliveri under sink water filtration system I attempted to replace the filter cartridge. I live in Perth Western Australia. When it was fitted I was told I could activate the alarm (battery operated led light and sound alarm) for a reminder in 12 months. It didn't work and I suspect the battery was flat before I installed it. I was also told I could easily buy replacement cartridges at Bunnings. Not the case. Bunnings (two stores) said they stopped stocking Bunnings 'years ago'. They recommended Trade Link who told me the same thing and advised me to order online. Trade Link also gave me the phone number for the Oliveri Warehouse (?) in Welshpool WA. I called them and they said they had no suitable cartridges and didn't know when they would have any. They also couldn't recommend anywhere in WA where I may be able to buy one. I don't buy online (don't trust it) but was forced to as the old cartridge had been in place for 12 months. I ordered and received the cartridge in about a week or more. I have since sent an email to Oliveri Customer Service about recycling the old cartridge and have yet to receive a reply several weeks later. Overall my experience with Oliveri is poor and I would not recommend the product to anyone.
