Within the swimming pool and spa industry, these tradespeople are also known as "pool and spa service professionals" and have two national trade associations that offer membership, IPSSA, the Independent Pool And Spa Service Association, Inc. [1] and UPA, the United Pool Association.[2] Certification can be obtained through various organizations, including the NSPF and APSA.
There are as many as 15,000,000 residential pools and spas in the United States and about 400,000 "commercial" or "public" swimming pools.[3][4] The two service industry trade organizations boast of having about 15,000 members, tops which means that each such professional who is a member would have 1,000 pools each to clean. Obviously there are many pool service professionals who are not members of these organizations and millions of pool owners clean their own pools.
According to the National Swimming Pool Foundation,[5] which has certified hundreds of thousands of pool service operators with its CPO or Certified Pool Operators course,[6] only 26 states require that operators of public or commercial pools require that they be properly trained and certified. But there is a move afoot by the Center of Disease Control on a grant provided by the NSPF to create the first ever uniform aquatic health code.[7] These servicemen generally clean either residential or commercial swimming pools.[8]
To properly clean a swimming pool, residential or commercial, a service professional, a residential pool owner or an employee of a commercial pool owner has a choice of manually cleaning the pool or using an automated pool cleaner if speed and efficiency is preferred.
A pressure-fed sand filter is typically placed in line immediately after the water pump. The filter typically contains a medium such as graded sand (called '14/24 Filter Media' in the UK system of grading the size of sand by sifting through a fine brass-wire mesh of 14 to the inch (5.5 per centimeter) to 24 to the inch (9.5 per cm)). A pressure fed sand filter is termed a 'High Rate' sand filter, and will generally filter turbid water of particulates no less than 10 micrometers in size.[18] The rapid sand filter type are periodically 'back washed' as contaminants reduce water flow and increase back pressure. Indicated by a pressure gauge on the pressure side of the filter reaching into the 'red line' area, the pool owner is alerted to the need to 'backwash' the unit. The sand in the filter will typically last five to seven years before all the "rough edges" are worn off and the more tightly packed sand no longer works as intended[citation needed]. Recommended filtration for public/commercial pools are 1 ton sand per 100,000 liters water (10 ounces avdp. per cubic foot of water) [7.48 US or 6.23 UK gallons].
Introduced in the early 1900s was another type of sand filter; the 'Rapid Sand' filter, whereby water was pumped into the top of a large volume tank (3' 0" or more cube) (1 cubic yard/200US gal/170UK gal/770 liters) containing filter grade sand, and returning to the pool through a pipe at the bottom of the tank. As there is no pressure inside this tank, they were also known as 'gravity filters'. These type of filters are not greatly effective, and are no longer common in home swimming pools, being replaced by the pressure-fed type filter.
