A kind comment from a recent customer.. "Initially we liked the website video which explained your product, then yours was one of the only websites which gave an offer price for the full kits online so we had an idea of cost from the beginning. A couple of calls later and we had a mutually convenient delivery time for our kit. It arrived on time, all in order with full instructions. The tank is beautifully made and fit together easily. Great product and great service. I would certainly recommend your Graf tanks/kits and service to potential customers."

Another kind comment from a recent customer.."We have been able to install our rainwater harvesting in our London terrace home with no professional help at all. For Jay and me, two people who have got limited DIY skills, this has been achievable. When it comes to electricians, plumbers, plasterers, I’m going to hand that on to somebody else. But I’m really, really pleased that both of us, Jay and I, have dug this hole, we’ve had the confidence knowing that what we’re doing here is right. We can do the work now, then for years and years to come this will be free water every time we flush the toilet, every time we wash our clothes, we know that we can look skywards and we’ll say “Thanks. You know; free water! Great." I’m over the moon”  More on case histories.

Lots of us already use rainwater from small waterbutts or waterbarrels for our garden watering. But rain collection in a 200 litre butt will not give much drought protection. We offer you bigger tanks at lower prices. We also offer a range of tanks adaptable to different locations: modular wall tanks that fit neatly against the house, large tanks that can be located away from the roof filling it and installed either above or below ground. Our range of accessories makes using rain water storage easier and more pleasurable. Filters and Syphons and help stop stored water turning brackish and sediment accumulating in tank bases and in taps and hoses. Pumps make distribution from the tank easier by maintaining good pressure.
