Since it's inception in !"#$ the pre%pressuri&ed potable water tank has assumed various designs and has proven useul in a wide variety o open%system applications. (riginally used in well installations$ this technology gained widespread acceptance and was soon applied in a variety o applications re)uiring pressuri&ed water storage. * ith this le+ibility$ however$ can come conusion as to installation scenarios and related si&ing. ,elow$ we'll take a l ook at proper use and related si&ing techni)ues in such applications as pump cycle control$ volume maintenance$ and water treatment systems.

-ommon to the below e+amples is the act that it is necessary to determine both the amount o tank storage needed and the pressures necessary to obtain that storage. Simply stated /ll si&ings use the same principle with dierent values. 0eerred to as ,oyle's 1aw o 2deal 3ases$ this principle will be used to determine how much water is stored in tank at a given pressure. This multiplier will be reerred to as the Acceptance Factor . 4eep this e)uation in mind as a oundation to si&e any pre% pressuri&ed tank
Pump Systems
2t is common knowledge in the water systems industry that cycling a pump motor rapidly will oten lead to ailure. To prevent this$ most pump manuacturers normally recommend a minimum pump runtime o 5 minutes. 2n order to achieve the runtime$ the pre%pressuri&ed tank must store a given volume o water between pump cycles. 6oing so re)uires the pump to run or a speciic period to ill the tank. 2n general$ larger pumps re)uire longer intervals between start cycles. *hen si&ing a pre%pressuri&ed tank or the above purpose$ the ollowing inormation should be known 7ump horsepower$ pump output in gallons per minute 837M9$ and pressure switch setting in psi 8cut%in : cut%out9. The below procedure will guide you through a si&ing scenario using a hp pump. The pump will be operating at ; 37M with a pressure switch setting o #
/ccording to the =0ecommended Minimum 0untime= notation$ a hp pump should operate or a period o at least 5 minutes between motor starts. 2n order to run a ;37M pump or 5 minutes$ >< gallons o storage is necessary. The /cceptance Factor indicates that 5@ o a given tank's volume will be usable water between #< and "
