I have a delta faucet in my bathroom. One-piece faucet. Hot water only was leaking. I pulled out the parts, replaced the spring and the rest of it. When I turned the main water back on underneath the sink, the water came straight from the faucet (did not turn handle on). In an attempt to figure out what was wrong, I looked at the cold water faucet to see how it was put together. Now I have the same problem with the cold faucet. How can I fix this? Thank you.
