… use and review starts in 3rd paragraph …Most of my house was destroyed here in the Florida Panhandle my Hurricane Michael. It may have disappeared from the country's view in a couple weeks. but now, later months later, my neighborhood still looks like blue tent city -- from all the roof tarps still in place as people attempt to fight insurance companies and get on waiting lists with roofing companies.… But I digress … I bought this because the pipes supplying water to my house that were destroyed by Michael's wind were finally repaired after 3.5 months. The downside was the drain line from the bathroom was clogged after sitting inactive for so long, the toilet, sink, and shower all took forever to drain.Snaking the drain did not correct the problem. My plumber recommended finding a company to camera the drain line and then, if it showed no signs of damage, hydro-blast it clean. Since my plumber's camera was in the shop for repairs, I opted to try my own hand at imaging the drain, rather than try a different unproven plumber.I ordered the DepsTech WF020X (B0785H3XR7) and ran it down the drain line. For my first use and its first job, the whole thing when very smoothly. At first I thought the image was over-exposed, until I realized I had turned up the LEDs all the way thinking the dark pipe would need every bit of possible illumination. Not true. The DepsTech only needed about 50% power to LEDs to create a great image of the pipe. The semi-rigid wire made pushing the camera through the pipe easy.When the first pass failed to show any obvious blockage, I took out the camera and installed the angled viewing mirror for another pass. I figured I would take a closer look at the walls of the pipe before I made a decision. As I advanced the camera down the pipe, I simply twisted the camera's cable to rotate the camera. This time I found were each bathroom fixture fed into the drainage pipe. The openings were very small. I couldn't figure out what was blocking the openings, but it appeared to be some smooth substance, like sediment.Next I took out the camera and hydro-cleaned the drain line. At first I started off at Amazon looking for a sewer jetter, and almost bought a JetSnake, but in doing my research, I found it was VERY IMPORTANT to match a sewer jetter (nozzle size and length of hose) with your pressure washer (psi and gpm). People in the questions' section saying the jetters work with any pressure washer probably don't understand how back pressure can ruin a pressure washer. I finally went with Clog Hog (who doesn't sell on Amazon - what a shame), where you have to select your pressure and gpm before selecting the sewer jetter. If you try to buy one that doesn't match your pressure washer, the company will sell it to you, but first, they will contact you and offer the correct model for your pressure washer. great customer service there.So I hydro-cleaned the drain line using my pressure washer, equipped with a Clog Hog. It took longer to set up the pressure washer then to do the job.After the hydro-cleaning, I ran my DepsTech back through the drain line once again. Once again the images were amazing. Even though this is not a Clog Hog review, I will say that the pipe after hydro-cleaning, compared with the pipe after power-snaking, was the difference of day and night. That drain line was CLEAN, and all the openings from bathroom fixtures were clear. Toilet flush, no problem; and the shower drains better now than I can ever remember it draining before.Having the DepsTech to show me the problem and verify the cleaning was awesome. Best of all, the DepsTech (and my Clog Hog) were still cheaper than hiring a plumber. Also, it was faster than hiring a plumber, since right row, plumber's around Panama City, FL are still booked solid 1-2 months in advance trying to repair hurricane damage.Next I used my DepsTech to look inside my AC supply ducts, which I suspected were damaged by the 155 mph winds ripping through my attic. My vent ducts are made of duct board -- a semi-rigid fiberglass board with a foil coating on one side. From the outside, the ducts looked dented but relatively okay. When I ran the camera through, I found that large sections of fiberglass had broken off the inside and were, in some cases, partially blocking the duct. I took pictures and sent them to my insurance company to have the AC ducts added to my homeowner's claim. They added the ductwork to my line item repair estimate. So now, my general contractor can contract someone to repair or replace the damaged areas. Best of all, since I have this little camera, when the sub-contractor says the duct work is finished, I plan on inspecting the job from the inside.This is a great product.
