Hydro Jetting Main line

[Snifferpro]

Is hydro jetting the main line from the house to the street effective?

Main line is 4 inch cast iron and camera views show the inside diameter decreased by about an inch
or more.

Using 1.28 gallon toilets and have had 2 clogs in about a year.

Prior to changing old toilets to new 1.28's I never had a problem in 14 years.

I've adjusted the fill valve to increase waterr in the tank to see if more water per flush avoids
future clogs.

In the event I get another clog after adding more water to flush, would hydro jetting be a reasonable
thing to try?

Also, what is a reasonable cost for hydro jetting?


Thanks

Jetting will remove any SOFT material, but will NEVER touch scale buildup, which is basically part of the pipe by now.
