Service professionals in the Southeast report to working with chlorine generated pools more than many other parts of the country. Salt water chlorine generators are on an average of 84 percent of the pools that they service.
Respondents from this region indicated that an average of 69 percent of the pools they service incorporate an automatic pool cleaner. Suctionside cleaners make up 63 percent of these, pressure-side 30 percent, and robots 7 percent.
For secondary sanitation systems, 27 percent of service techs encounter UV on at least one of the pools that they service, 18 percent encounter ozone, and less than 1 percent see Advanced Oxidation Processes AOP technology.
Respondents indicated that about 1 percent of their total pools utilize UV or ozone.
The Northeast includes Connecticut; Delaware; Maine; Massachusetts; New Hampshire; New Jersey; New York; Pennsylvania; Rhode Island; and Vermont. The Northeast represented 6 percent of the total number of responses that we received in this year’s survey.
About 80 percent of those responding to the survey reported that they use trichlor to sanitize the pools they service. Dichlor, calcium, and liquid chlorine are all used by about 60 percent of those responding to the survey.
Respondents from the Northeast declare an average liquid chlorine cost of $3.15 per gallon, and $218 for a 50-pound bucket of trichlor tabs. For trichlor, this works out to $4.83 per pound of available chlorine.
For Dichlor, respondents indicated that they pay between $8.21 and $7.42 per pound of active chlorine, depending on whether or not it is anhydrous. They pay a median price of $4.80 per pound of available chlorine for calcium hypochlorite.
For testing purposes, most professionals reported to using test strips, employed by 80 percent. However, DPD is also a popular testing method with 40 percent of respondents using this method.
