How to tell when cartridge needs cleaning
There are a few different ways to tell when the cartridge needs to be cleaned. A lack of good water flow is a definite indication that the cartridge is either dirty or needs to be replaced. If you clean the cartridge as described in this article, and flow is still not what it should be, chances are it may need to be replaced. Another indication is observation of the pressure gauge. I've seen many filters in which the pressure gauge is broken. It's a good idea to have a good working pressure gauge. There actually is a reason that that these are on the filters. Depending on a number of different things, your filter, when clean or new, will have a "normal" or clean pressure reading such as around 12 psi. Again, this may vary depending on your system. To determine this, of course you'll need to have a new or clean filter. Once the pump is turned on and fully primed, check the pressure gauge. Should be between 10 to 15 psi. Lets say it reads 13 psi. Rule of thumb is that 10 psi higher than the normal or clean reading would indicate that the cartridge should be cleaned. In this case it would need to read around 23 psi(10 psi more than 13).
