Waste of time and money. Installed the first block and Valla was leaking at both the inlet and the first stage filter. My inlet side stopped flowing, just tightened it a bit. I called Amazon and they refunded my money. They told me to keep the old one and I bought the same one again to use as a spare. The second arrived with changed parts and was still leaking. This is the worst filter system. I had to go with reviews.
