 Re: reduce/eliminate TTHMs (Trihalomethanes)
Pentek (Pentek makes American Plumber products) does not have any whole house filters that reduce Trihalomethanes. The flow rate would be much too slow. We have two under sink systems that reduce TTHM’s, and they both need drinking water faucets because the flow rate is slow to in order to reduce TTHM’s. 2 drinking water filter options for TTHM’s: 1) The first drinking water filtration option is the Pentek US-1500 system. This system is installed under the kitchen sink and comes with a faucet and installation equipment. There is a filter set included with the purchase of the system. The US-1500 can be purchased on the following page: http://www.waterfilters.net/culligan/undersink/housings/SY-2650.htm 2) The 2nd drinking water filtration option is the Culligan 350 system. The faucet and the system are purchased separately on the same page. We sell the faucet separately in case you already have one you would like to use. The filter is also included with the purchase of the system. This filter is really easy to replace – you just unscrew it and screw a new one in. http://www.waterfilters.net/culligan/undersink/housings/Culligan-Preferred-350.htm It is still a good idea to get a whole house system to reduce sediment, chlorine taste and odor, and other contaminants: For a whole house system, you would need a Big Blue Whole House Housing. There are 3 different inlet/outlet options so be sure to select the correct one for your pipe size – ¾”, 1”, or 1.5”. http://www.waterfilters.net/culligan/wholehouse/housings/20_BigBlue.htm The RFC-20BB filter that your plumber recommended is located here: http://www.waterfilters.net/Pentek/wholehouse/Carbon_Filters/RFC-20BB.htm The CBC-20BB would give you greater contaminant reduction by also reducing cysts. The flow rate is slower however since there is more contaminant reduction: http://www.waterfilters.net/Pentek/wholehouse/Carbon_Filters/CBC-20BB.htm Some people install 2 Big Blue Whole House Housings. The first whole house housing is used to reduce sediment. This preserves the carbon filter (which is more expensive) since most sediment is reduced before reaching the carbon filter. A popular sediment filter is the DGD-5005-20: http://www.waterfilters.net/culligan/wholehouse/replacement_filters/DGD-5005-20.htm Thank you, WaterFilters.NET  |
