I just put a new set of pads in my filter and my gauge shot up very quickly.
Check to see if you have placed your pads and/or filter plates in the filter housing correctly.
Identify the type of wine you are making to the grade of pad you are using. If your gauge rises quickly, this means that your pads are blinding (clogging) quickly. You may need to filter with a coarser pad.
Do not start filtering from the bottom of your container, especially if you have sediment. The pump could draw the sediment into the pads and quickly blind them. Start filtering about half way down your container.
The gauge increases in pressure proportionately to the saturation of the pads. The more saturated your pads get the more back pressure is created, therefore the higher the pressure on your gauge.
Always flush out your pump well after use and avoid getting solids into your pump. This will make your check-valve last longer.
Clean and dry off the whole machine prior to storage.
Rack your wine prior to filtering.
Lubricate your tightening screw with petroleum jelly or food grade grease. Keep the screw running freely.
