Installation
Does this system soften water?
No. The WGB32B-KDS whole house water filter prevents scale buildup and protects pipes and appliances from corrosion. It does not remove calcium or magnesium, so water hardness remains unchanged. For softening, see iSpring WCS45KG
What contaminants can this system remove?
Turbidity, visible particulate matter, sand, silt, dirt, rust, chlorine, taste, odor, THMs, VOCs, chemicals, herbicides, heavy metals like lead and mercury, hydrogen sulfide, scale, and corrosion
Can I install this system outdoors?
Install indoors in a well-ventilated area, shielded from wind and rain, away from direct sunlight and heat. Consider water leakage protection. For outdoor installation, ensure insulation for frost, sun, and waterproofing for both unit and pipes.
Can I use this system if my water flow is from left to right?
Yes, you can. However, please note that the inlet/outlet marking on the system is fixed, so you will need to flip the machine head to accommodate this setup. To do this, simply unscrew the screws on the machine head and flip it.

New water filter system.

Bought and installed thissystem 6 months ago. It has completely changed my waters tastes and smell! The first shower made me think - why did I wait so long to put a filter system on my well water supply...

Works Great!!!

At my plumber's recommendation we installed an iSpring whole-house filter system. After seeing all the debris the filters have removed from our water I'm very happy we decided to install them.I also want to give a special thanks to Nick for his outstanding customer service. We had a minor issue after installation and Nick went above and beyond to make sure everything was resolved quickly and to our complete satisfaction. He was extremely knowledgeable responsive and genuinely helpful throughout the process. He made sure the issue was corrected promptly and followed up to ensure we were happy with the outcome.I can't thank him enough for his excellent support. It's refreshing to receive customer service like this and I highly recommend both the iSpring filter system and the company behind it.

Excellent Customer Support

I purchased this product a little while ago and after replacing the filter cartridges I noticed a slight leak from around where the O-rings seal. I determined the leak was from the black cap itself. A replacement part was sent to me immediately after contacting I-Spring. Nick from customer service was outstanding in his support of the product!

FAQs

Will WGB32B-KDS 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-KDS 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.

Does WGB32B-KDS 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.
