Two new five-horsepower pumps which run on 575 V three-phase power and controlled by a variable frequency drive (VFD) were also installed. This new system will reliably pump the pool water through the system to be filtered while saving the owners a lot of money compared to the old energy sucking pump that did not use a VFD.
The chemical control system was upgraded, too. It comprises a new chemical controller that is connected to peristaltic pumps to feed liquid chlorine and muriatic acid as required to keep the pool water constantly sanitized to regulated levels per the Ontario health code, Health Protection and Promotion Act, R.S.O. 1990, c. H.7. This controller measures pH, ORP, temperature, as well as free chlorine in parts per million (ppm). The free chlorine reading is now required by the health code and helps operators see more easily what the pool’s chlorine level is. This controller offers a true ppm reading of the free chlorine in the water, opposed to other units that calculate a derived ppm which is not as accurate.
The pool shell was also completely stripped of all existing paint, and a few areas were repaired where the concrete was deteriorating. This allowed Acapulco Pools to repair all the cracks by V-cutting, priming with epoxy, and filling with a non-shrink grout. The V-cut helps the repair material to ‘key’ into the crack, creating a mechanical bond in addition to the chemical bond between the patch material and the concrete.
There were also a few areas where the rebar had to be replaced and new concrete was poured. The entire shell was then coated with a layer of thin set to leave a solid, sound, and smooth surface to paint. Finally, two fresh coats of epoxy pool paint were applied throughout the pool to protect all the shell repairs, leaving a brilliant new finish for the pool.
