Had www.leakdetective.ca in brantford ontario come over to find a leak in our pool they showed up and tried to find the source of the leak was unable to find our leak his equipment that pressure test the return lines malfunctioned. Told us to close all the lines and let the pool lose water until it stopped. Paid in full $395 pool still leaks he would not return to find the leak. Rude, poor customer service. Unprofessional. Huge waste of time and money. in my opinion Avoid at all costs.
