SHURFLO 94-800-03 Model 4008 Repair Parts - Check Valve

Part was the exact replacement !

This “off-center” version works fine on my camper water pump, Shurflo 4008-101-A65, manufactured 11/2017. We bought this camper used, so no idea if a prior owner changed out the housing on the water pump. Be sure to compare your current check valve to the pics for this product to be sure you need the off-center version. This part fixed my issue of city water flowing thru the pump and into the freshwater tank, eventually causing the fresh tank to overflow.

READ THIS- the recent reviews and pictures complain that this “off center” version of the part will not replace the older “centered” version. This did not fit either my 2015 version nor my 2019 version. I called Shurflow support to ask why not. I was told they did a redesign on the pump upper housing (black plastic end piece) about 2020, which included a total redesign/reshape of the check valve, AND, they kept the same part numbers for the pump (4008), the upper housing (94-800-00), and the check valve (94-800-03). They did not assign a new part number to the new check valve. (shame, shame, shame). They did not continue production of the original check valve. They did not separate inventory nor spare parts. You cannot order a replacement for the old design. You can only order a completely new upper housing, which will come with the new design check valve. Its overly expensive at about $40. A new 4008 pump is about $74. Shame on you Shurflow. The actual rubber flapper of the old design and new design is about the same diameter at 19.33 mm (.7610). But the new flapper is considerably thicker, with a rounded over edge. I considered trying to use only the new flapper, but I didn’t want to mess around with it. Instead I cleaned the mineral scale debris from my old flapper and reinstalled it, and it seems to be working fine. So- if you order this in 2022 and beyond you’ll receive a non-centered version for manufacture date after approximately 2020. Do not buy this for the centered version from 2019 and prior.

Fit my 2015 model year 4008-101-A65. Mfg date on new valve was 09/26/24. Can't comment on why some reviews state this won't fit older models. Just passing on my experience as a positive fit for an older model 4008.

I got this from the reviews. It sounded like this fit the newer pumps NOT.It fit my old original OEM 4008-101-A65 pump from 7/18/2014. Not my 4008-101-A65 replacement pump from 2023FIts earlier models 2014

Worked perfectly!!

worked well . was only 1. shows multiple but not I didn't need more than one

Does not fit a 4008. The bag the valve comes in says fir model 4008! The instructions say 4048. As someone else said, this one is off center and will not work!
