I checked it's accuracy (by volume) monthly for six years. It remained accurate the entire time. It is much easier to pump out a certain number of pumps for a given layup than it is to measure with a scale. If you keep track you will soon be able to accurately estimate the number of pumps for a given area of fabric. If your pump is sticking it may not deliver accurately and you should spend the money for a new one. I believe they sold replacement pistons for less than the entire pump. You should keep the pump at a constant controlled temperature. David Scale hands down.

I have a pump that I bought used and can't seem to get it working smoothly despite a lot of cleaning. Seems to me a scale and cups are easier to keep clean and monitor rather than the pump? Any thoughts? Will
