Water heater valve leak help
A few weeks ago, I noticed there was water in the bucket that has a hose from what I believe is the pressure valve on the water heater. When the propane company came a few days later to clean the furnace, I told them about it. They replaced the valve. But a few days later, there was again water in the bucket. I went through some papers and found that the water heater was quite old and decided to just replace it. New water heater was installed about a week and a half ago by the propane company. Today I noticed there is a little bit of water again in the bucket.
Since I know nothing about plumbing, what sort of problem am I having? Is this a major water pressure problem that requires more expertise than the furnace techs? I have lived in this house 7 years and never had this happen before.
Thanks for any advice you can give me.
