Stop your window air conditioner from leaking water with this  QB-KIT1 Drain Plug Kit, a simple and effective solution for restoring proper drainage in window AC units, mini splits, and HVAC systems.

This drain plug is commonly used in window air conditioners and ductless systems to seal unused drain openings and control condensate flow. If your AC unit is leaking water inside your home, dripping onto the floor, or not draining properly, a missing or damaged drain plug is often the cause.

Instead of dealing with water damage or replacing your unit, this quick fix can restore proper operation in minutes.

Common Problems This Drain Plug Fixes:

  • Window air conditioner leaking water inside
  • AC unit dripping water onto floor or wall
  • Water leaking from back or side of window unit
  • Condensate not draining properly
  • Missing or cracked drain plug
  • Mini split indoor unit leaking water
  • Air handler leaking from unused drain port

Key Features:

  • Commonly used in window air conditioners and mini split systems
  • Seals drain openings to prevent leaks and water damage
  • Helps restore proper condensate drainage
  • Quick and easy installation
  • Compact, durable design

Product Details:

  • Part Number: QB-KIT1
  • Type: Drain Plug Kit
  • Applications: Window AC units, mini splits, air handlers, HVAC equipment

Compatibility & Use:

This drain plug is widely used in window air conditioners and may also be compatible with mini split systems and other HVAC equipment depending on size and configuration.

Compatibility is not guaranteed for all models—please verify fitment or contact us before ordering.

Why Your AC Is Leaking Water:

Most window air conditioners and mini splits rely on proper drainage to remove condensation. If a drain port is left open or the plug is missing, water can leak directly from the unit instead of draining safely outside.

Common Use Cases:

  • Replacing a lost or damaged drain plug in a window AC unit
  • Fixing indoor water leaks quickly and affordably
  • Redirecting water flow during installation or maintenance
  • Sealing unused drain holes in mini split systems

Additional Notes:

  • Stock images may be used
  • Professional installation recommended
  • Verify size and fitment before ordering

Before replacing your air conditioner, check the drain—this small part is one of the most common causes of AC water leaks.

Great shirt - tail could be longer - great color selection - No 1000 pins to remove!
Special Size: Standard, Size: X-Large, Color: Aroyal Blue
Favorite shirt, fits well, looks good, durable. I'd like if the shirt tail was longer. All cotton so they shrink a bit after washing and need to stretch back out. Overall, I'd like if they were a touch larger or I was a touch smaller. I love that they don't have a HUGE AMAZON BASICS label on them. And I LOVE that I don't have to spend thirty minutes removing tiny stick pins like other dress shirt makers force you to do - what a waste!

Reliable, well-made shirt with a slightly lighter color than expected
Special Size: Standard, Size: X-Large, Color: Navy, Special Size: Standard, Size: X-Large, Color: Navy
This Alimens & Gentle Oxford shirt is a solid, well-made option that holds up well over time. After roughly 20 wears and washes, it’s proven to be durable and fairly resistant to wrinkles, which is a big plus for a cotton button-down. Fit & Comfort: The fit runs a bit on the loose side, but it’s still comfortable and easy to wear. It’s not a slim fit, so if you prefer a more tailored look, keep that in mind. Material & Performance: The fabric is thicker than most standard dress shirts, which makes it a great choice for cooler weather. It provides a bit more structure and warmth, but it may not be as breathable in the summer months. On the plus side, it washes and irons well and maintains its shape over time. Appearance & Versatility: The shirt pairs well with both dress pants and jeans, so it works in both professional and casual settings. One thing to note — the actual color is noticeably lighter than what’s shown in the listing. In my case, I still liked the look and kept it, but it’s something to be aware of when ordering. Bottom Line: A dependable, slightly heavier Oxford shirt that’s great for fall and winter wear. Best for those who prefer a relaxed fit and don’t mind a small variation in color from the listing.

What A Find! Unbelievable Quality and Price!
Special Size: Standard, Size: Large, Color: Plaid-light Blue
I can't believe the quality of this shirt!! I ordered the blue checked one for my husband for a costume. The price was right and I didn't expect much, as it was just for a costume. It came packed into a little box, which I figured showed it would be super thin and cheaply made, but didn't really care as only needed it for one time. Woah!!!! I opened the box and was absolutely floored by the quality and heft to the material. It is crazy. I don't know how they get this shirt into that box, but it is baffling. This shirt is of high quality, with all the seems sewn well. The fabric is every bit as good as the brand of oxford shirt that costs 3 times the price of this one. My husband goes between medium and large. He takes 16" neck in dress shirts. We ordered the large and it fits well. Has a little room, but not in a too big type of way. I washed it once before wearing, and it washed well. Not much shrinking at all. It ironed very easily without a problem. Yes, it is 100% percent cotton. Because of the quality and fit, I will now order additonal colors. My husband loves this shirt. This is an excellent buy!!!

Great shirt!
Special Size: Standard, Size: X-Large, Color: Dark Green
My partner loves this shirt and is very particular. He likes the green color and that it is cotton. Bought more colors from this company. Runs true to size.
