The Aqua-Glo:
They will last indefinitely unless physically damaged.
Send the remaining standard to us for evaluation. We may be able to make a new match for it. If we cannot, then you will have to buy a new set, GTP-835.
You can buy a new set, GTP-835.
As long as the seal on the barrier bag is not broken, they should last indefinitely. However, if a pad has turned yellow, then it has spoiled and is no longer fit for use.
Call us, and we will advise you as to whether or not you need to return the unit to us.
Our instruction manual explains that you must calibrate it every time you use it.
If you need to return an Aqua-Glo for repairs, see the Return Service page.
The Gammon Gauge:
As long as the piston falls within the zero range on the scale when at rest, you do not need to calibrate the Gammon Gauge.
If the piston will move freely in the glass cylinder when removed from the gauge, the spring must be replaced.
Disassemble the gauge. Clean the glass with a Scotch brite pad. Do not use anything else. Reassemble the gauge. If the piston still will not move freely in the glass cylinder when removed from the gauge, you can either return the gauge to us or replace the glass and piston. Never send in a gauge that has fuel in it!
