Most homes today have problems with tap water. It may contain a lot of impurities, and this water can wreak havoc with modern-day plumbing systems and appliances. It makes sense to install whole house filtration systems, and occasionally you may need to change the paper or plastic cartridge filter. Here are some tips to help make the job easier.
Most water filtration professionals recommend changing filters about four times a year (every three months). This keeps your water pure and tasting good. Always use the right kind of plastic cartridge filter and make sure it is for whole house systems.
Turn Water Off
Whole house systems do not have individual shutoff valves. You need to shut the water off to the entire house. Main shut off valves are sometimes in basements, crawl spaces, and some water meters have shutoff valves.
It is not safe to remove the filtration unit without depressurizing it. Turn on one of your water faucets before attempting to remove the plastic cartridge filter. The filter unit is pressurized and is very difficult to remove while still under pressure.
You May Need a Wrench
Housings unscrew for filter removal. They are sometimes hard to remove, and you may need to use a strap wrench.
Once you remove the old filter, clean the housing. It may contain water deposits and minerals. You can wipe it out with a cleaning rag or paper towel. Next, install your new filter.
Before you turn the water back on, shut off all the faucets. Once the water is on, check the housing for leaks. Make sure to write down the numbers from the old filter, so you know which filters to buy for future filter changes. In fact, it is a good idea to buy several filters at a time.
