Types of Cartridge Filters

There are several different types of cartridge filter housings. The pictures used in this article are for a basic capsule-style housing. Some may accept band clamps in the center, others may have fly basics on the pinnacle, and some even have a series of small cartridges. The cartridge cleaning process itself is the same.

How to Clean the Filter

On a level surface, rinse the cartridge with a good hose nozzle from acme to lesser as shown in the motion picture. Do not apply a pressure washer as this tin can impairment the filter element. Continue rinsing from top to bottom turning the cartridge around until clean. That's it. Supplant in housing and turn the pump on.

Tip: Ever take annotation of the force per unit area. If information technology becomes higher each time you put the clean filter dorsum in, it's a sign you may demand to supplant information technology. There are means to get more than time out of your cartridge.

Rinse from tiptop to bottom.

Extending the Life of the Filter

The filter is made up of pleated cloth. Over fourth dimension, the folds in the pleats tin can build up residual that cannot easily exist removed with a rinse. If yous spread apart the pleats and wait in, you may see some discoloration and rest. When this occurs, you'll notice that y'all need to clean the filter much more than ofttimes.

This residue tin exist broken down past soaking the filter in Tri-Sodium Phosphate, available at your local pool store. I have found that using total-strength hydrochloric acid on the cartridge works very well.

Notation: I only do this if I am replacing the filter and merely trying to get a few more days of filtration out of it. This is Non good for a filter. I cascade the acid directly on the filter cartridge covering every bit much of the element every bit I can, leaving information technology to eat away at the residual for iii or 4 minutes. The fumes tin be overwhelming and information technology WILL damage the filter, so I don't recommend it unless yous plan on replacing it very shortly.

How to Tell When Cartridge Needs Cleaning

There are a few unlike ways to tell when the cartridge needs to be cleaned:

• A lack of skilful h2o 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 menstruation is even so not what information technology should be, chances are it may need to be replaced.
• Another indication is ascertainment of the force per unit area gauge. I've seen many filters in which the pressure approximate is cleaved. It'southward a practiced idea to have a expert working pressure gauge.

How to Read a Pressure Gauge

At that place's a good reason 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 around 12 psi. Again, this may vary depending on your system. To make up one's mind this, of grade, you'll need to have a new or clean filter. Once the pump is turned on and fully primed, check the pressure level estimate. Information technology should be between 10 to 15 psi. Permit's say it reads 13 psi. A rule of thumb is that ten psi higher than the normal or clean reading would betoken that the cartridge should be cleaned. In this case it would need to read around 23 psi (10 psi more than xiii).

Relieve air pressure.

When to Go a New Filter

Although the cartridge tin be cleaned, information technology does eventually need to exist replaced. My experience has ever been that if, even after being acrid washed, the filter but does not let water to catamenia through it, and the pressure builds within in 10 minutes, it's time to replace the filter.
