It's not a stream, but not drip by drip, it's kinda a stream like drip. I done have the brand or model, he had lost he papers.

You should have about 60psi on that line so I don't think that is a problem. Credible membrane manufacturers rate their membrane at normal household pressures. Some RO units come with adjustable flow restrictors which need a lot of attention and if not set right can give you problems, Aquasafe has these. How much waste water are you getting? Usually 4:1 is normal so if you fill up a cup of ro water you should get about 4 cups of waste water, if you are getting a lot more waste water than that you have a problem. Sediment filters are cheap so it can't hurt to change it. My unit has an inline flow restrictor with a valve that cam be opened to back flush the membrane out, if you have this on yours give it a 5 minute flush.
