I bought a new water hose at Sam's. It's a real heavy one. I didn't notice
any problem the first time I used it, but later on I went out to run some water
in a bucket to water flowers. The water was soapy. Husband said, must be the
bucket. Next time, I was washing off patio...water came out soapy. Changed to
clear after few minutes. This happened again recently....

We unscrewed hose and ran the faucet...water fine. Waited a day and tried
again; water clear.

There must be something inside the hose...but what?

If I had to guess based on your description....SOAP!
