Frequently Asked Questions
Q: With this whole house system, do I still need to install a water softener if my water is very hard?
A: Yes, a water softener is needed if your source water has a high level of hardness, usually with TDS higher than 700 PPM. Hard water can reduce the lifespan of whole house water filter cartridges. The harder the water, the greater amount of scale buildup occurs, and the sooner the filters get clogged.
This whole house water filter can remove up to 95% of sediment, chlorine, rust, pesticides, herbicides, industrial solvents, and various other contaminants that a regular water softener can't, although it does not soften your water. It is recommended that you install this WGB32B whole house system after your water softener to achieve optimal performance if you have hard water.
To determine which product best suits your need, it is recommended that you get a professional water test done prior to purchase to identify the main issue of your source water.
NOTE: Water Softeners and whole house systems usually do not lower the TDS level of the water. An additional Reverse Osmosis system may be necessary for your drinking water. Please consult iSpring professionals prior to purchase if you are unsure of which product will meet your needs.
Q: What type of Whole House Water Filter do I need?
A: If you are on municipal water that isn't contaminated with heavy metals like iron, manganese and lead, the WGB32B is the system to go with. Naturally occurring metals are a commonplace in most well water sources however, and that is where the WGB32BM or WGB32B-PB earns its keep. If you are on well water or have heavy metals in your municipal water supply, you may want to consider the WGB32BM or WGB32B-PB over the WGB32B. For removing the common contaminants found in the majority of municipal water supplies however, the WGB32B fits the bill.
Q: What flow rate should I look for?
A: Measured in gallons per minute (GPM), flow rate determines the amount of water available to run your shower, toilet, hot water heater, dishwasher, etc. When calculating your requirements look at the demand ratings printed on your appliances and toilet. Depending on the size of your house and family your water flow rate requirements may range from 5 to 40 GPM.

Product Description
Style:Fine Sediment and Carbon
The WGB32B whole house filtration system is a "point of entry" filtration system for cleaning up water supplies to a home or business on municipal (city) water. Unlike "point of use" systems (like reverse osmosis systems) that are installed to supply water to a specific faucet, the WGB32B filters your water from the source. This means water from every output in your home or business will have passed through the three filtration stages of the WGB32B. So what exactly do these three stages of filtration offer?
Used as the first stage of defense on the system, the stage 1 housing holds a 5-micron polypropylene sediment filter. This filter removes dirt and other various larger-sized particles from the water that can clog the following filters.
The second and third stages of the WGB32B house 5-micron CTO coconut shell carbon block filters. Block carbon is finely ground up carbon packed into a solidified block. They knock out bad tastes and odors, combined to remove up to 99% of chlorine from the water, and also remove pesticides, herbicides, and industrial chemicals.
If you are on well water or have unusual contaminants in your municipal water supply, you may want to consider the WGB32BM over the WGB32B. For removing the common contaminants found in the majority of municipal water supplies however, the WGB32B fits the bill.

Does WGB32B whole house water filter system address TDS reduction?No, it doesn't. Only RO systems will lower TDS levels. You can find our best Reverse Osmosis system here. What is the difference between 10 inch whole house filter and 20 inch whole house system?The main difference is the capacity of the cartridges. The WGB21B 10'' inch home water purification system has 10'' X 4.5'' cartridges that feature 50,000 gallons of water capacity, while the 20'' whole house cartridges feature around 100,000 gallons of water capacity. The average American household water consumption is approximately 300 gallons per day. Therefore, the cartridges inside of the WGB21B would last 50,000/300=166 days (Around 6 months) on average. If your family consumes more water than 300 gallons per day, you may need a 20'' whole house system to fulfill your needs. You may need to look at your water bill to figure out how much water your family consumes monthly. Will WGB32B whole house water filtration system decrease water pressure to the house?It should not. If you experience significant pressure loss, please let us know. What are the water pressure requirements for the WGB32B residential water treatment systems to work?The feed water pressure needs to be between 25 psi and 80 psi. Is this domestic water purification system suitable for well water?This whole house water purification system can filter both city water and well water. However, it doesn't filter out viruses and bacteria. For well water, a whole house UV stage (#UVF55FS) is recommended. Will the WGB32B whole home water systems help with high sediment in well water?It will help, but depending on how much sediment you have, it may exhaust the filters quickly and cause you to replace the filter frequently. In this case, you may want to look into purchasing a spin-down sediment pre-filter (e.g., WSP50). It will help trap more sediment and extend the life of your other filters. Does WGB32B home water filtration system work on hot water?No, we do not recommend installing a water filter for home to filter hot water as the high temperature can damage the carbon block filter. The operating temperature for the whole house system is 40 - 100°F. Does this water filter system for home filter fluoride?This whole home water filter system does not remove fluoride. You will need a Reverse Osmosis system to remove fluoride. You can find our best Reverse Osmosis system here. Does WGB32B home water treatment system filter calcium for hard water?No. You need a water softener to filter out calcium. Please check out iSpring WCS45KG whole house water softener here. Does this whole house water system reduce Chlorine?Yes, the CTO carbon block filters remove chlorine, cloudiness, odor, taste, and other contaminants. Will the WGB32B water purifier for home remove the hydrogen sulfide (rotten eggs) smell?Yes, but it might shorten the filter life. If there is a strong rotten egg smell in your water, we recommend installing WGB32B-KS or WF150K whole house filtration systems instead. Does the WGB32B home water system remove iron, lead, and other heavy metals?The whole house filter system WGB32B is designed for water issues with contaminants that create foul tastes, stains, and odors. Please check out WGB32BM, WGB32B-PB, and WGB32B-KS for removing pollutants such as iron, lead, manganese, and other metals or heavy metals. Is WGB32B whole home water filtration system a water softener?No. If you need a water softener or saltless water descaler, please check out here. Is the flow left to right, right to left, or can it go either way?Right to left, but you could switch the bracket to change direction. Can this water filter be installed on the exterior of a house? My house has no basement or crawl space, just a concrete slab.We would not recommend installing the system outdoors or anywhere where the system would be exposed to the elements, such as freezing temperatures, UV damage, and other forces of nature. Where do I install the system?You should install where the main water line comes into the house before it splits to the water heater or other plumbing. Will WGB32B home water purification systems \"easy\" to install? I am not a plumber, and it's so difficult to find one.You can install the home water purification systems by yourself if you have some plumbing knowledge. Will the inlet and outlet accept threaded PVC couplings?Yes. As long as they are 1\" threads, it will work. Do I need a storage tank for this whole home water filtration system?Our whole house water filtration systems have a large water flow capacity and do not require a storage tank. In what order do the replacement filters go?For WGB32B, the water flow goes to the polypropylene (PP) filter first, then the carbon block (CTO) filters. Do all filters need to be changed at the same time?No, they don't. What size O-ring does WGB32B home filtration system use?O.D.: 5-3/4\", the model number of this O-ring from iSpring is ORBX2. How often do I need to replace the cartridges?It depends on the quality of your feed water. Typically, for a standard American household, the filters can last around one full year. If you notice the output water pressure drops significantly, it is time to replace the filter cartridges. Why did my output water pressure drop a lot?If this water cleaning system was just installed, it could be that the filters were installed incorrectly, or a piece of the plastic wrapping is still protecting the filter cartridges. If you installed the filter a few weeks ago and suddenly the pressure dropped, it can be due to clogged filters. |
