A splash guard is a rubber or plastic ring that sits just below the sink opening and keeps water and food scraps from splashing out while the disposal runs
The splash guard wears out over time—the rubber cracks, hardens, or tears, and pieces may fall into the disposal itself. Replacing it is a straightforward job that takes about 10 minutes and requires no special tools beyond what you likely have in a kitchen drawer. You do not need to remove the entire disposal unit.
The guard sits on top of the disposal's upper collar, held in place by friction or a snap ring depending on your model. Once you remove the old one, you straightforward drop the new guard into place. The part costs between $15 and $40, and you can order it by the disposal's brand and model number.
Key Takeaways
- Turn off the disposal at the wall switch and unplug it before touching any part of the unit.
- The splash guard pulls straight up and out of the collar—no tools needed, though a flathead screwdriver can help pry if it is stuck.
- Order a replacement by your disposal's brand and model number, which you will find on a label attached to the unit itself.
- The new guard drops into the collar the same way the old one came out, and you do not need to tighten or find it further.
Locate your disposal's model number before you shop
The model number is printed on a label stuck to the side or bottom of the disposal unit, usually near where the power cord enters. Write down both the brand name (InSinkErator, Waste King, Moen, Badger, or another) and the full model number. Take a photo of the label with your phone so you have it when you order.
Search online for "[brand] [model number] splash guard" to find the exact replacement part. Most manufacturers sell them directly through their websites or through plumbing supply retailers like Ferguson, Lowe's, or Home Depot. Confirm the part number matches your model before ordering—splash guards are not universal, and the wrong one will not fit properly.
Turn off power and remove the old splash guard
Switch off the disposal at the wall switch, then unplug the unit from the outlet under the sink if it has a plug. If the disposal is hardwired (connected directly to the electrical box with no plug), turn off the breaker that controls it. Wait a few seconds to be sure the motor has stopped spinning.
Look down into the sink opening. The splash guard is the rubber or plastic ring sitting just below the rim. Grip it firmly with both hands and pull straight up. It should come free with steady pressure. If it is stuck, slide a flathead screwdriver under the edge and gently pry while pulling upward. Do not twist or rock it side to side—pull straight up.
Once the old guard is out, look inside the collar (the metal ring at the top of the disposal) for any debris, food particles, or rubber fragments. Wipe it clean with a damp cloth or paper towel. A clean collar helps the new guard sit properly.
Install the new splash guard
Remove the new splash guard from its packaging and inspect it for damage. Hold it over the collar opening and align it so the notches or tabs (if it has any) line up with the grooves in the collar. Lower it straight down into place. It should sit flush with the collar rim and feel snug but not forced.
Push down gently on all sides to make sure it is seated evenly. The guard should not rock or shift when you press on it. If it feels loose, remove it and check the collar for debris or damage. A warped collar or a guard that does not match the model will not seat properly—if this happens, double-check that you ordered the correct part for your disposal.
Test the disposal before you finish
Plug the disposal back in or switch the breaker back on. Run cold water into the sink for a few seconds, then turn on the disposal briefly. Watch for any splashing around the guard or water leaking from under it. The guard should contain all spray and debris inside the sink bowl.
If water or food particles spray out from under the guard, turn off the disposal when ready and check that the guard is seated all the way down. Remove it and reinstall it, making sure it is fully seated. If splashing continues, the guard may be the wrong model—contact the manufacturer or the retailer to confirm you have the correct part.
When to call a plumber instead
If the collar itself is cracked, warped, or damaged, a new splash guard will not seal properly. In this case, the disposal unit may need to be replaced. If you cannot locate the model number or cannot find a replacement guard for your specific model, a plumber can order the correct part and install it, or advise whether replacement of the entire unit makes sense.
If the disposal is leaking from the bottom or sides, or if the motor does not run, those are separate issues unrelated to the splash guard. A plumber should inspect the unit before you spend money on parts.
Frequently Asked Questions
Can I use the disposal without a splash guard?
Technically yes, but you should not. Without the guard, water and food scraps spray out onto your counter and clothes. The guard also prevents large objects from falling into the disposal chamber, which can jam the motor.
What if the new splash guard does not fit?
Double-check the model number on your disposal against the part number on the package. If they match and the guard still does not fit, the collar may be damaged or warped. Contact the manufacturer's customer service with your model number and a photo of the collar.
Do I need to remove the disposal to change the splash guard?
No. The guard sits on top of the collar and pulls straight out. You do not need to disconnect any plumbing or electrical lines. The entire job happens at the sink opening.
How often do splash guards need to be replaced?
Most last three to five years depending on how often you use the disposal and how well you maintain it. If you notice cracks, hardening, or pieces missing, replace it right away to prevent debris from falling into the motor.
What should I do with the old splash guard?
Rubber and plastic splash guards can usually go in your regular trash or recycling bin, depending on your local program. Check your municipality's guidelines for plastic disposal.
