If the drain guy used a snake to clear the lines you may as well take the same amount of money and put a match to it as you would get the same results.

If you ever went to a beach as a kid or played in a mud pile then you may under stand the following.

Imagine filling a bucket with mud and water and placing your finger in it NOW picture your finger is a snake as soon as you pull your finger out the mud closes up again so you accomplished nothing but getting a finger dirty.

Now take the same bucket and put a garden hose in it and see the mud flush harmlessly away.

That is the principle of water jetting a soft stoppage.

Any master plumber will explain it BUT the franchise drain guys are not as well versed in the technical aspects of drain cleaning as who knows more about drains then the folks who installed them (Plumbers)

Jetting will scour the lines to an almost like new condition and flush away all debris, except roots and hard stoppages like rags etc.

You can also use a finer mesh screen to prevent leaves and soil from entering the system and check the storm traps after heavy rains.

I am sorry to hear they only used a snake as that is not the proper job.

See the picture?

A roto guy snaked a tiny hole in this lead pipe just enough of an opening to allow standing water to flow out.

To bad the folks in the art center below trusted the work as the next heavy rain storm everything below was flooded out causing several hundred thousand dollars of damage.

Look carefully and see the tiny opening in the mud caked 5" lead pipe

Thank you for your reply. I believe I may have been confusing. They didn't use a snake, but a power hose. The problem seemed to be that the little storm catcher I put in the drain, caused the debris to catch on it, to the point that it was so thick with mud, it wouldn't let the water move past it. So, I removed the little screen. I was wondering if I should build up the sides of my walls, to help the dirt from not falling over into the drain? Also, are there different types of drain filters that wouldn't prevent the water going through the pipe, when they catch the dirt?

What I normally do with a yard drain is to make a deeper sump then normal so this way the sump gives the building owners more time to clean the sump. The deeper sump allows for more sand,soil to collect and less chance of this debris entering the storm system.

Placing bricks /black top will stop most soil from entering the sump/drain but may also allow water to accumulate and that would cause another problem.

FYI The high pressure hose is called Water Jetting

Iam sorry but what is a drain sump? Should I hire a plumber to do this, and what should I look for with a good plumber?

Thank you
