Countertop Water Filter Replacement Parts


Call us at (940) 382-3814

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.

Filter Housings

Part # Description Price

White Housing, “King Style”

Our favorite countertop housing. Easy to screw apart for filter changes. This housing is strong enough for undersink service if you decide to convert it.

Clear Housing

Diverter Valves

Part # Description Price
CP502 Diverter Valve, Standard, with 1/4" compression fitting. This is an easy-action top quality valve, made for years of service. Tip: The best way to free a sticking diverter valve is remove it from the faucet and drop two or three drops of vegetable oil into the small hole where the water enters the valve. This simple maintenance procedure can add years of life to the valve. Try this before you order a new diverter valve. $14.00 Add to Cart
CP503 Diverter Valve, Toggle Switch, 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. $17.00 Add to Cart
CP501 Diverter Valve, Return-style, with one 1/4" compression fitting and one 1/4" barbed tube connector. This is the valve 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. This is the replacement diverter for our Multipure VOC countertops. $17.00 Add to Cart

Stainless Steel Spouts and Spout Elbows

Part # Description Price
CP010 Long Reach Spout, stainless steel, with tip, and double o-ring connection. The long-reach spout reaches further over the sink than the standard spout, making it easier to fill bottles and cooking vessels. The double o-ring connector simply pushes into the spout elbow. This is the spout in the second picture on the page. $8.00 Add to Cart
CP001 Standard Spout, stainless steel, with tip, and double o-ring connection. The double o-ring connector simply pushes into the spout elbow. This style spout is often called a “goose neck” spout. This is the spout in the top picture on the page. $8.00 Add to Cart
CP003 Spout Elbow. Connects the spout to the filter housing. The double o-ring spout simply pushes into the spout elbow. $7.00 Add to Cart

Tubing and Tube Elbows

Part # Description Price
TB003 Countertop Standard White Tubing; sold by the foot. Strong but very flexible vinyl tubing, for countertop use only. Not designed for high pressure use or use with quick-connect fittings. Three feet is plenty for most countertop filters. $0.75 Add to Cart
TB006 Countertop Double White Tubing; sold by the foot. Vinyl double tubing to carry the water to and from the filter. This tubing is for use only with "return" style diverter valves (like CP502, above). Three feet is usually plenty. $1.25 Add to Cart
CP002 Tube Elbow. Connects the inlet tube of the unit to the housing with a simple compression fitting. No tools needed for installation. $7.00 Add to Cart

OR006 O-rings for Slimline Housings. $2.00 Add to Cart

Miscellaneous Parts

Part # Description Price
CP004 Faucet Adapter. Standard two pack of metal adapters for male threaded faucets. Sizes included are 13/16" X 27 thread and 15/16" X 27 thread. Most faucets end in a male thread. This pack adapts the two most common sizes of male thread faucets to a standard diverter valve. We also stock female adapters (adapters for faucets with female threads), and you're welcome to call for information. However, it's often easiest to go to a good hardware store. $2.00 Add to Cart
CP008 Nipple, 1/4" with O-rings. (Joins double filters, or can be used to create your own double filter from a single filter and an extra housing.) This is a high quality QMP nipple with o-ring seals. $3.00 Add to Cart
