“This place rocks! I have replaced two parts for an old Gerber faucet in the laundry tub. After the spout was leaking, I could not find the right washers anywhere. I had to replace the whole spout, which they had in stock, and it was priced competitively. Now, not a drop leaks. ”

“I sent in photos of a broken cartridge (still installed, couldn’t take it out myself due to water shut-off restrictions in a condo) and even with the limited view they were able to tell me the exact part I needed so I could have it ready for the plumber (meaning I didn’t need to pay for a plumber to come out twice!!) ”
