The question is did he clear out a grease build up that was plugging your line? If he did then the best solution is not a treatment but a change in what you put down your drains.
The main problem with grease buildup in drain pipes is that there is very little that you can actually do about it. There is nothing on the public market that will touch grease build up. There are commercial products that will burn through grease but they are highly toxic, as well as caustic. I do not recommend that you try and use them as they are extremely dangerous to use and can ruin drain pipes if used incorrectly.
The best overall solution is to first make sure that any type of grease is not poured in the drains or washed out in the dishwasher. mostly things like frying pans, woks, and deep fryer components are the guilty items when it comes to grease getting into your lines. If you must wash these things wipe them out with a paper towel first. That will stop the grease from building up any more than it already is. After that you will just have to wait till a line plugs up and then have it cleaned out. If you like there are services that will come into your home and run a camera down your pipes and record a video of what your pipes condition really is. You can then plan the cleaning of them accordingly. Or just wait it out and see what happens. This is dependent upon your personal budget,
The boroscope service will run you $300.00 to $600.00 to have done depending on how many pipes you have.
