Unfortunately we had to send our product back. This was because the product purchased meant you had to install an extra tap. We thought that this could be installed onto the mains water supply to the kitchen tap. This wasn’t how the system works. This needs to be made more clear when purchasing. However return was excepted and we are now talking to an advisor on an alternative product which will for fill our needs. This is very good service and I wish I had spoken to an advisor in the first place. So to anyone who wants to purchase a system I would recommend speaking to one of the team first.
