We were looking for a suitable gray water system for our property. After looking at other models we were advised to go to Aquablock. Yes, they had the goods and we have it installed and are very happy. The ladies on reception are lovely, friendly, helpful and polite. The plumbers, when you can get them, are also friendly, but that's the problem, getting hold of them. But, it's not just that, it's the attitude, it always seems like a bother. Having said that, they will do things for you and chase up information, but you get the impression that you're putting them out. Writing this is actually very difficult trying to pinpoint what we're not happy with. It's like I've said, they're friendly and helpful (eventually), but the accompanying attitude is off putting. We use them now when we have to, but prefer to bypass them if possible.
Update. We've had nothing but problems with our system and we finally had a fellow from another company come out to service our machine. He pointed out everything that was done incorrectly - a bit alarming - but at least now our system is running smoothly :)
