Febco Repair Kits

Here is a list of the more common Febco backflow assemblies.  I have left off of this list the detector models but often they are the same parts or are at least listed in the maintenance manual with the double check and reduced pressure models.  They even share some parts with the double checks and reduced pressure assemblies.

Please understand that the prices that come up are list prices.  For contractors please contact us for your discount code by calling us at 801-355-6736 or email at sean@backflow-supply.com or you can request a quote or place an order if you do not want to go through the shopping cart.  Pricing for shipping will be better through the order page or calling us than through the shopping cart.

These sheets are a list of available kits with a description of what is in the kits and if available a picture.  At the bottom is a link to the repair and maintenance information and to the list price booklet.  You can click the part number and it will take you to the item in our store where you can select the quantity and submit it to the cart and you can check out that way.

Additional Information

Febco repair kits are available for all current models and some no longer in production models.  Some of these kits are for a range of sizes and others for one size only.  Additionally, some kits are for more than one model.  For example, for an 825Y 2″ and smaller model the check rubber kit for the 805Y is the same kit for the check rubbers on the 825Y.  For 2 1/2″ and larger assemblies some kits will also interchange.  An example would be the seat kit for the 850/860/870/880 is the same.

“Regular” vs “Lead Free”

It is important to know if you have a “regular” assembly meaning it contains lead above allowable limits or if you have the “lead free (designated as LF).  Parts for the “regular” and “LF” sometimes are interchangeable but sometimes they are not.  Generally speaking for 2″ and smaller they are.  But for the 2 1/2″ and larger assemblies they are completely different.  Not just different material but designed differently which is the case for the 850/860/870/880’s vs the LF850/LF860/LF870/LF880’s.


Most repairs require no special tools. On some older models you may need some tools but that should be rare.  Febco in their maintenance manuals have provide instructions for making your tools.  You can go to Febco’s site and type your model in the search field and after locating the model you have select the maintenance manual and look in the back of the manual for the instructions.


Febco used to do a better job at providing a real exploded view of their models.  Now they are more compact and difficult to determine what they are pointing to and there is little useful information in the description name. Below I have provided a list of the more common assemblies.  These are sheets for your convenience to help you see what is in the kits and link you to an exploded picture and then enable you to put it in your cart.
