Vacuum Heads and Hoses; tools

Vacuuming a pool is necessary to have a sparkling clean pool. In the old days, a pool was rectangular in shape with straight walls and a sloping bottom from shallow to deep. The vacuums were aluminum and not flexible. They were heavy and cumbersome, but with the introduction of a curved bottom pool, the vac heads were made to flex. With new plaster one had to use a brush vac so no wheel marks were left in the soft and curing plaster. After a month of using the brush vac, the plaster was hard and ready for the wheel vac. The flexs vac had 8 wheels on it for the standard size, 14 in. The silicone wheels were much better, they lasted longer. To vacuum a pool, the sides and the steps are brushed. The vacuum is put in the shallow end and one works toward the deep end, let gravity work with you. The vac hose comes in several lengths, depending on the size of the pool. A 30 ft. hose was ample for most pools. For larger pools the hose can be connected with shorter sections to suit the size required. Before inserting the hose to the suction line, all the air must be removed from the hose. If it is not you may loose the prime in the pump. With above ground systems it is time consuming and sometimes difficult to prime. With pool service a vacuum a week was mandatory.
