Countertop Water Filter Replacement Parts

The parts on this page are for sale only to those who foolishly bought a countertop filter that isn't a Model 77.

That's because replacement parts for Model 77 are free to owners of our authentic Model 77 units, which have a lifetime parts guarantee (only the filter cartridges are excluded).


Parts for all standard countertop water filters, including spouts, diverter valves, spout and tube elbows, o-rings, tubing, faucet adapters, and more.


Parts on this page are those used on our world famous, often imitated but never equaled Model 77 Countertop, “the world's greatest $77 water filter.”

The spouts, diverter valves, and tube and spout connecting elbows are all American-made by our favorite small parts maker, QMP of California.

Tube connections are made with compression fittings, so it's easy to replace parts on your current unit, even if the tube connections on your non-Model 77 countertop are made with clamps or barbed fittings. To install parts on your countertop filter with 1/4" tubing, simply cut the tube squarely, back the nut from the fitting onto your tube, work the end of the tube over the barb, and screw on the nut. You have a tight compression fitting that won't leak. No tools needed except scissors to cut the tube.

If you have trouble identifying the parts on your countertop, or if you aren't sure our part will work for you, please call or email for advice.

Part # cp502
Add to Cart
Connects to tubing with 1/4" compression fitting. A high quality alternative to the Standard Diverter Valve with a manual, smooth-action toggle switch. Because this valve is not spring-loaded, the countertop filter can be operated at reduced flow rates ideal for precision flow-control.

Connects to tubing with one 1/4" compression fitting and one 1/4" barbed tube connector. Used on “return” style units which have no dispensing spout. Water enters the valve, passes through the filter, and returns to the valve from which it is dispensed into your container.
