I'll place some photos soon. I recently purchased a used Pasquini Livia 90 for around $550. I did this because I used to own a Bezerra 99 and my Friend Chris had a couple of Livia 90's that I had missed out on purchasing from him. Lesson learned if Chris offers to sell me anything I just buy it. I recently bought a sony a6000 for my daughters upcoming trip to france and Switzerland, and I have bought my macbook air from him...all at killer prices. Back on point, my espresso machine worked great only complaint I had was the pump was really noisy, and when pressure built up it didn't get quiet like most pumps it became very loud. So I pulled the machine apart a few times, secured pipes and placed cardboard in between potential contact points....slight improvements in noise. Finally i pulled it apart and read a guide on rebuilding the Ulka pump. It's very simple but there are a lot of parts. Despite my descaling the pump had rust and was somewhat disgusting, when I opened it up fully I noticed that one of the springs was now two springs...
I looked into buying a replacement spring but that seemed almost good money for bad...ended up buying a pump from Amazon with free one day shipping. Pump is quiet and powerful now..I also visited the local home-brew place and replaced one of the water lines that had better days.
The new pump is a big improvement.
