These Filter Housing Bypass Kits are made to be used in conjunction with the Big Blue Housing Install Kits. Adding a bypass to your Big Blue Housing helps to make changing filters easier by providing a way to bypass the filter housing in the event of a clogged filter cutting off the water supply to the house. This also is important should something happen to the housing to cause damage or a leak so it can be bypassed and not interrupt water flow to the house by simply closing the inlet/outlet valves. This is available for 1" and 3/4" tubing sizes. Kits Include: 3FT PEX-B Tubing (2) Stackable Stem Tee (3) Stop Valve (2) Union Elbow (2) Male Adapters Product Catalog Housing Install Kits Catalog .catalog a{ text-decoration: none; color: #24a7bd; transition: ease, 0.3s; cursor: pointer; } .catalog a:hover{ color: #2276c5; } .catalog h3{ text-align: left; text-transform: uppercase; font-size: 16px; font-weight: 900; font-family: Jost, sans-serif; letter-spacing: 0.1em; padding: 40px 0px 20px; color: rgb(80, 81, 79); border-bottom: 1px solid rgb(225, 225, 225); margin-top: 20px; margin-bottom: 20px; cursor: default; }
