Big Bubba is a unique water filtration system made by Watts Water Technologies, America's premier maker of water treatment products. Here are some of its outstanding features.

Big Bubba is Big

Big Bubba is very big as cartridge-style water filters go.  It has 2" inlet and outlet ports and uses specially made cartridges with large diameter centers to ensure as little flow restriction as possible.  It can support a flow rate of up to 150 gallons per minute with a pleated sediment cartridge, and even the carbon block version is designed for service flow peaks of up to twenty gallons per minute. 

Big Bubba is Tough

Big Bubba's glass reinforced polypropylene case, together with the stainless steel clamps and eyebolts that connect the cap, can withstand a 300 psi burst pressure. Big Bubba has a working serbubbawithcartridgevice capacity of up to 125 psi (as compared with 80 psi for most "Big Blue" style housings).  Its materials are so corrosion-resistant that it can be used in sea water applications.

Big Bubba is Simple

Big Bubba comes in one style only, with no frills.  It has a top-mounted pressure gauge to monitor the inner water pressure, and the installer can add a second gauge on the outlet side to provide a pressure-differential monitor as an indicator of cartridge condition.  There are no electronic controls and no electrical connection is needed.

Installation is very simple.  Big Bubba has 2" slip inlet and outlet ports.  It is provided with 3 ports so that it can be installed as a straight-through inline or in a reverse flow (horseshoe) design. (A cap is provided for the unused port.)  Big Bubba is designed so that multiple units can be easily installed in parallel (side by side) or in series. 

Maintenance is also very simple.  Big Bubba cartridges are provided with a handle and they lock in place in the housing with a turn of the wrist.  No tools are needed. The lid removes with easy-to-use stainless steel swing bolts. Again, no tools are needed.

Big Bubba is Versatile

Big Bubba can serve as a very high flow sediment filter or a high volume whole house filter for residential dechlorination.  It can be installed as a single unit, in tandem to provide an exceptionally high-flow system, or in series, to offer varying levels of filtration.

Big Bubba can provide more than 150,000 gallons of whole house chlorine removal on a single cartridge, or it can be used as a whole house residential sediment filter where high flow rates are needed. It can be an economical commercial or industrial filter, serve as a prefilter for large reverse osmosis units, or be used in seawater applications where a corrosion-proof housing is necessary. There are many industrial, commercial, and residential applications.

Big Bubba is Economical

Compared with tank-style filters of similar performance capacity, Big Bubba is inexpensive to purchase and inexpensive to operate. It uses no water for backwashing and no electrical connection is needed. There is no electronic control valve to repair or replace.

Big Bubba as a Whole House Chlorine and Chemical Reduction Filter for City Water

Big Bubba is clearly the ideal system for long-term, trouble-free whole house residential service for city water users. The 5-micron carbon block filter has been rated for 150,000 gallons of chlorine reduction at a flow rate of 12 gallons per minute. (Most residential water use is at 4 gallons per minute or less, so the cartridge should last longer. Carbon filter life is proportional to the rate of service flow.) Flow rates of up to 20 gallons per minute are possible with the carbon cartridge. Best of all, because of the size and design of the unit, there is only a two psi pressure drop at 12 gpm with the carbon cartridge, less than one psi at 5 gpm.

Big Bubba as a Sediment Filter

Big Bubba is available with 10 sediment removal cartridges to choose from. The free-flowing , high volume pleated cartridges come in six sizes, from a very tight one micron absolute to to a free flowing 150 micron mesh cartridge. Five, 20, 50, and 150 micron versions of the pleated cartridges are cleanable and reusable.

In addition, four sizes of spun polypropylene depth cartridges are available--one micron nominal, five micron, twenty micron, and fifty micron. Depth cartridges are preferred for use with gelatinous substances and certain chemical issues. Depth cartridges are not cleanable.
