A filter’s stress measure is the tool familiar with measure a filter’s psi. The facial skin of this gauge is clearly marked down in increments of people or tens and usually has a maximum value of 50-60 psi. The “normal” psi rating for specific swimming pools will vary as a result of factors including filter dimensions, pump power and feet of head. The “normal” stress could be the baseline psi reading after huge filter cleaning cycle or following the installation of brand-new filter media (brand new sand or recharged DE grids). For instance, if your typical baseline psi reading is 10 psi proper your gauge checks out 18-20 psi (eight to ten psi above your filter’s typical running force) it is the right time to backwash your pool filter.
