Review 1 for Valley Instrument Grade A Stem Mount 1 1/2in. Glycerin Filled Gauge - 0-15 PSI
October 17, 2007
"I placed this gage on my swimming pool filter to measure back pressure. As you desire an accurate reading to identify when to backwash the filter. I found the gage reading to be off by about 3 pounds, and when I removed the gage the needle did not return to the zero peg. The needle fell to 3 lbs and remains in that position. I purchased a Glycerin filled gage to achieve better accuracy. This particular gage did not work for my situation."
