There was weeping noise immediately after installation, some of these old ones are sometimes good, but this pump started leaking in less than a month. We are a professional shop and this is my personal machine so installation error is unlikely. That being said, the company will send a replacement and give me a 30 day window to return the faulty pump. I will keep you posted on the replacement, received the replacement quickly, installed and it sounds a lot better as long as there are no leaks. Very impressed with the return policy, fingers crossed that returning a faulty pump goes smoothly
