Frequently Asked Questions

General

Q: Which whole-house model is best for me?

A: Experience has allowed us to approximately match the square footage of a home to the right size filter (see brochure chart). Of course, the number and age of people in the home are also factors. The brochure chart is figured assuming two adults and two children are occupying the residence. If from using the chart, you are debating between two units, and the square footage isn’t too far off, let your home’s occupancy be the deciding factor.

Q: Should I use WaterMan filters if I’m NOT on municipal water?

A: Yes and No. With consultation, we may be able to provide an appropriate filter depending upon the problems involved.

Q: Why is water filtration so important now?

A: Because there are greater concentrations of more pollutants in the water than ever before. The ongoing ingestion of small amount of over 200 chemicals cannot be good for anyone.

Filter Specifics

Q: What is in the filter?

A: We use the best granular activated carbon available – coconut shell, instead of coal because it is three to five times more absorbent – as well as the specialized media KDF (Kinetic Degradation Fluxion) that targets heavy metals, pesticides, chlorine and other contaminants. All of the media we use is of the highest quality, with the best absorption properties, producing the highest quality filtered water. Click here for an in depth look into our filters.

Q: What are the measurements of the whole-house filter?

A: The floor footprint of our filters ranges from a 6” diameter circle to 7”, 8”, or 9”. Height also varies from 35” to 48”, with 44” being the norm. Width is affected by the pre-filter housing that extends from the top of the main tank horizontally for a total top space including tank and pre-filter of about 2 feet.

Q: What contaminants do WaterMan filters remove?

A: The combination of coconut shell GAC and KDF in WaterMan filters creates a top-quality filtration system that targets heavy metals, chemicals such as chlorine, pesticides, herbicides, THMs, drugs, odor, taste and much more. The filters are bacteriostatic and control algae and scale as well. Click here for a table of specific contaminants removed by WaterMan filters.

Q: Do WaterMan filters take out fluoride?

A: No. Fluoride is commonly added to municipal water for prevention of tooth decay, and the way in which water treatment plants infuse the fluoride to the water molecule makes it impossible for carbon filtration to remove.

Q: Are WaterMan filters bacteriostatic (meaning bacteria won’t grow in the tank)?

A: Yes, WaterMan filters are guaranteed to remain bacteriostatic for two years. This is one of the main reasons rebedding is necessary.

Q: Do WaterMan filters reduce water flow?

A: No. We size the filter tank and the plumbing so that water pressure is not affected. This is the primary reason that larger homes require larger filter tanks.

Rebedding

Q: How long will my whole-house unit filter?

A: We guarantee two years of effective filtering. After that we cannot be sure that your unit is getting out all of the chemicals or, more importantly, that it will remain bacteriostatic. It is important to rebed your filter when its guaranteed effective life is over. Just one or two people using less than a normal amount of water may get a few more months out of the filter, but in no case should more than two and a half years go by between rebeds.

Q: How long will WaterMan undersink units filter?

A: WaterMan undersink units are guaranteed to effectively filter for three years. After three years the undersink filters must be replaced.

Q: What does it mean to rebed the filter?

A: The media bed inside the whole-house filter must be replaced every two years. We use the term “rebedding” to describe this process. After two years, you can buy a whole-house rebed filter at a significantly reduced cost. We ship the rebed tank to you and you simply have to switch out the old tank with the new tank. The new filter is then guaranteed to filter effectively for another two years.

Q: Will I need to pay the same price every two years when I rebed my whole-house filter?

A: No. You only pay for the new media bed when you rebed. Cost is determined by the size of the main filter. Rebed costs range from $280 to $320. For more specifics on rebeds, scroll to the bottom of the Residential Products page.

Q: What do I do with the old tank once I have rebedded?

A:You can either leave the tank in a box on the curb for your garbage man to pick up (it is safe for general disposal as directed by Deparment of Transportation Regulation No. 40 CFR ) or you can mail the tank back to us and receive a $40 credit on your account. We recommend draining the tank as much as possible before you mail it to reduce postage costs. For latter option, securely package filter, include your information, and mail to:

  • The WaterMan
  • P.O. Box 14791
  • Columbus, OH 43214

Installation

Q: How is the whole-house filter installed?

A: We require whole-house filters to be installed with a complete by-pass using three ball valves so that it is simply a matter of turning the valves to circumvent the filter. For detailed installation instruction click here. For a diagram of the suggested installation click here.

Q: Where is the whole-house filter installed in my home?

A: Whole-house filters must be installed where the water comes into the home and before the water goes to the hot water tank or anywhere else in the home. That way the unit is sure to filter all the water, both hot and cold.

Q: Does the whole-house filter require a backwash and/or drainage?

A: No. We do not believe backwashing can fully cleanse any carbon or KDF media bed properly, and insist that replacement of the media bed is the only way to keep the filter effective and bacteriostatic over time.

Q: How is the undersink filter installed?

A: The undersink filter must be installed on the cold water tap of your sink only. The filter comes equipped with two fittings and tubing to make the install as easy as possible. The undersink also has a Ceramic Faucet option that would allow you to have a separate tap on your counter for filtered water. Make sure it is possible to cut a small hole in your sink or countertop before choosing the separate faucet option however. Porcelain sinks cannot be drilled.

Maintenance

Q: What maintenance is required to keep my filter working?

A: Very little. Your WaterMan whole-house filtration system includes a small sediment pre-filter that filters out larger impurities (dirt and undissolved solids) before your water goes through the large main filtration tank. We recommend changing the small white pre-filter every four months or so in order to keep the main filter working at its best. The WaterMan provides these six pre-filters with purchase of the filter at no additional cost.
