Helpdesk for your questions 
Can I get advice about installing the system?
Yes, drop a quick line to our email helpdesk and we will answer any questions you have. Even if you aren't sure about something - just drop us a line and we will sort it out. There is also a telephone helpline for customers who have already purchased their Ontap Water Filter System.

Can I adapt my current system or fridge to your filters?
Yes, we have two kits available for converting most filter systems or refrigerators using 1/4", 5/16" or 3/8" plastic pipes to Ontap Filters, but drop a line to the helpdesk to put your mind at rest if you aren't sure which kit to buy or if it will fit your current system or fridge.
Our conversion kits will even fit Triflow taps such as BRITA, DEVA & "Str3am".
