Risers allow easy access from the surface to tanks installed underground. Risers must be secured and sealed to the top of the tank to prevent the intrusion of run-off or ground water.

Testimonials

  • “Just wanted to tell you I designed a system around the flout for the Affordable Housing Association here on Denman and it worked like a charm. Your worksheet worked well and the dose pressured up the field evenly for about 3 minutes. I called the person who will be living in the house, he went and saw the squirt test and was impressed with the whole idea of dosing with no electricity as he is the one who will be paying the bills! Cheers and thanks.”
