I have been using Graham Water Systems for over 10 years without a complaint.

Once a year I get Bob to test my water, change my R.O. filter, and service whatever systems need attention. After more than 10 years, all of my equipment is running without fail. Bob knows what he is doing!

Graham Water Systems is our preferred supplier of all water treatment systems for all of our new home purchasers. We only use Graham Water Systems because we know that the job will be done right, that Bob will stand behind everything he installs, and most importantly that Bob services what he installs. A lot of companies will install a system, but only a few service them.

Bob is very professional, and we that’s what we want for our purchasers.

Punctual, Friendly, Reliable, Helpful!

We just recently moved to Waterloo, and our home has an osmosis water purifier and a water softener: both new to us. We chose Graham Water Systems from the yellow pages and have been very pleased with the service and value. Bob has patiently educated us on how to use the appliances, offered friendly and helpful advice, and done an excellent job servicing both appliances. We highly recommend him.

We are absolutely delighted with our new water filtration system. All the worries about what kind of water we are drinking and showering in are gone. A drink of water now tastes like I remember it as a child! As well, there is no need to fuss with bottles of water or manual water filters. We both feel that we have done something positive for our health.

Thank you for being our reliable support for our softener as well. It certainly is comforting to know you are only a phone call away.

Best regards,

Stephanie von Schilling,


I would recommend Bob to any of our friends. He shows up on time, completes the job in the time frame stated and leaves the work area spotless. Bob demonstrated a genuine and honest approach to our water concerns and at no time appeared to be pushing for the sale.

Graham Water Systems Inc. installed a water softener and fresh water system in our home and from the moment the filter system was installed the water quality improvement was dramatic. Clearly demonstrated in our daily showers. It simply feels healthier.
