A tile saw with a cracked or missing water pan is a saw that cannot be used. This is the genuine MK Diamond plastic water pan, part number 150634-MK, for the MK-100, MK-101, MK-101 Pro and MK-770 EXP wet saws. It is the part tile setters, stone fabricators and rental yards reach for when the original pan has cracked, warped or gone missing between jobs, and it puts a working saw back on the job the same day it arrives.
Use cases
- Replacing a cracked or leaking pan on an MK-100, MK-101, MK-101 Pro or MK-770 EXP
- Restoring a used or auction-bought saw that arrived without its pan
- Keeping a spare pan on the shelf so a rental or fleet saw is never down waiting on a part
- Replacing a pan whose drain plug has been lost and which no longer holds water
- Refitting a saw for indoor or finished-space work where a leaking pan is not acceptable
Why the pan is worth replacing rather than patching
The water pan does more than catch water. It is the reservoir the pump draws from, so the water level in it determines whether the blade is being cooled properly. A pan that leaks down over an afternoon starves the pump, and a blade that runs short of water gets hot, cuts slower and wears faster. The cost of a chipped cut or a prematurely worn blade adds up faster than the pan does.
It is also what keeps slurry off the floor. On finished interiors and occupied buildings, a pan that leaks masonry slurry onto a client's floor is a problem well beyond the saw. Plastic construction is deliberate here: it will not rust in a part that sits full of water and slurry for its whole life, it stays light enough to carry and empty by hand, and it will not leave rust staining on finished surfaces.
Because this is the genuine MK part rather than a generic tray, the mounting, drain position and dimensions match what the saw frame expects, which is the part that goes wrong with substitutes.

Frequently asked questions
Which saws does this pan fit?
MK lists this pan for the MK-100, MK-101, MK-101 Pro and MK-770 EXP. Model naming changed across production years, so if your saw is older or was bought secondhand, send us the model and serial number from the data plate and we will confirm the fit before you order.
Does it come with the drain plug?
Yes, the pan includes a rubber drain plug. The plug is the part most often lost on a used saw, which is one of the common reasons crews end up replacing the pan rather than patching it.
Can a cracked plastic pan be repaired instead of replaced?
Field repairs on a cracked pan rarely last. The pan flexes every time the saw is moved and holds standing water all day, so patches work loose and the leak returns, usually onto whatever the saw is sitting on. Replacing the pan is the more reliable fix.
Why plastic rather than steel?
Plastic will not rust, which matters for a part that sits full of water and masonry slurry for its whole service life. It is also lighter to lift and carry, and it will not stain finished surfaces with rust runoff the way a corroding steel pan can.
How do I get the most life out of the pan?
Drain and rinse it at the end of the day rather than letting slurry set up in the bottom, and support it evenly when you carry it. Dried slurry adds weight, hides cracks and makes the next cleanout harder than it needs to be.
