Disassembly of 21295C Spray Gun for Repair

If you're experiencing any issues with your spray gun and have eliminated other equipment as the culprit, you may need to disassemble the gun to diagnose the problem. Make sure to follow these instructions when doing so. For more details and a parts breakdown, consult the operating manual listed on this page under "Manuals."

1. Remove the seven cheese head screws (item #19) that secure the two halves of the housing together. Remove housings.
2. Remove the cap, springs, and ball.
3. With a hooked screwdriver, pull seat and O-ring out. Pull control bolt out. You may have to pick the O-ring out of the valve body with a small, hooked instrument.
4. Grease O-ring and control bolt and insert back into valve body. Make sure it slides easily. Put O-ring on seat and push into place.
5. Assemble in reverse order.

Important Operation Information

• Do not use acid concentrates through gun.
• Never secure the gun in an open position (trigger pulled back) by means other than the operator's hand. Bodily harm may occur if the operator loses control of the gun.
• Always engage the trigger locking mechanism when not in use.

Related Giant Spray Guns

The spray guns below have the same PSI and GPM specifications as the 21295C but have slightly different attributes that may be more suited to your preferences or application requirements.

Weep

• 21495CB has a brass discharge fitting that offers slightly more durability and longevity than the 21295C that has a plated brass discharge fitting. 
• 21295CX has a larger valve seat that allows even more weeping than the standard 21295C model. This is useful in extremely cold climates where an increased weep flow is needed to avoid freezing.

Non-Weep

If you're looking for a non-weep spray gun with the same PSI and GPM specs as the 21295C, consider the Giant 21290C with a brass discharge fitting or Giant 21250B with a stainless steel discharge fitting for top notch durability and corrosion and chemical resistance.

Deciding Between Weep and Non-Weep Spray Guns

Choosing between weep and non-weep spray guns is important for car wash operators, especially when cold weather is a factor. Weep spray guns are designed to allow a constant, low flow of water through the nozzle even when the trigger is released. This steady trickle helps prevent water from freezing inside the gun or plumbing lines, which reduces costly downtime and repair needs during winter months. Non-weep spray guns, in contrast, shut off completely when not in use, which can result in standing water freezing in cold conditions. Therefore, weep guns are almost always used in self-serve car washes or tunnel prep stations located in regions where temperatures regularly drop below freezing. However, for wash locations in warmer climates or for certain specialized cleaning jobs where water conservation is needed, non-weep guns might be preferred. Consider your climate, the type of wash setup you operate, and the potential risk of freezing when deciding which spray gun style best fits your business.

It's important to note that weep guns like the 21295C are almost exclusively used in car wash applications. Unlike car washes, pressure washing professionals don't have their high-pressure pumping unit operating constantly. Rather, the pressure washer is used for a job, cleared of all water and pressure, and stored away until the next job. Because of this, there is not the same risk of freezing as a constantly operating car wash, therefore no weeping is needed. In fact, a weeping spray gun would be undesirable for pressure washing.
