Filter Housings are available in a few basic Styles and Sizes with varying Thread Sizes, With or Without Pressure Relief, etc...
Typically one would decide between 10" or 20", Slim Line or Big Blue Style, Body and Cap Color, Port Size, Pressure Relief, etc. This decision may be based on water demand, flow rates, temperatures and available medias. Media choice depends on your water quality. The advantage to a Cartridge Style Filter is Higher Flow Rates, Higher Media Capacities, and longer life for those conditions. Also Available is our RED HT Series High Temperature Filter Housings, great for use on Water Heaters to reduce sedimentary build up and prolonging the life of water heaters. Remember, algae and bacteria can piggyback on Sediment and old filters, so regularly changing your filters is important. It's better to have no filter system at all, than a derelict system that is harboring mass quantities of harmful algae and bacteria.

WARNING: READ THESE INSTRUCTIONS BEFORE CHANGING OR INSTALLING. FOLLOW THESE INSTRUCTIONS TO REDUCE RISK OF DANGER.
CAUTION: Filter housing must be protected against freezing and extreme temperatures. Filter housings should not be in direct contact with sunlight for a prolonged period of time since uv rays can make housings brittle. Pressure should always be measured before installation and water pressure regulators should be installed in the main line or in front of the housing if water pressure exceeds manufacturers’ maximum water pressure: 100 psi. Installers should make sure filters and replacement filters are the correct length and are not too long so as to not cause undo strain and stress on the housing. A leak detector must be installed on all installations where high pressure, water hammer and pressure spikes are known or suspected to be present and on all installations where pressure is over 60 psi. Failure to the above may result in cracking of the filter housing, water leakage and water damage.
CAUTION: All filtration systems contain other parts that have a limited service life. Exhaustion of the service life of those parts often cannot be easily detected. Commonly, it is only after leakage has been observed or water damage has occurred that one is made aware that the service life has been exhausted.
IMPORTANT NOTICE: To prevent costly repairs or possible water damage we strongly recommend that the bowl or sump of all plastic housings be replaced periodically: every 5 years for clear sumps, and every 4 years for opaque sumps. If your sump has been in use for more than the recommended period, it should be replaced immediately. Be sure to date any new or replacement sump for future reference and indicate the next recommended replacement date.
WARRANTY: Limited three (3) year factory warranty from the date of sale for material defects only. Factory Warranty is limited to repair or replacement of product only. Any misuse, mis-installation, lack of maintenance, exceeding maximum pressure or failure to follow these instructions will void limited warranty.
