Hired Hyper Flow when we noticed waste water coming up in our laundry room floor drain. They sent out a tech who cleared the sewer line, by entering through the basement toilet line. They used a metal line with a camera on the end to scope the line and, as we expected, there were tree roots in the line, which is common in Denver. We've had them cleared before. Tech said he'd send me the video and we never got it (this cost $250). He also recommened hydro-jetting the line, which I agreed to. A few days later they came back, jetted the line, filmed it, and then said we had a sunken portion of the sewer line and it was never going to drain right unless we repaired the line. Another $750 and no video the second time either. Contacted the owner and got the video sent to me with an apology.
We agreed to have the sewer line replaced rather than repaired, because the cost difference was silly. They came back a few days later to replace the line. I've seen this done before so I knew what a big job it was. I have a large corner property that's fenced and together we planned where they'd enter with their equipment ...what section of fence would come down, etc. I prepped the day before and dismantled sections of interior fence lattice that separate portions of my garden etc. and removed raised garden beds that were in the way of where the backhoe would enter from the street onto the property.
On the day of the service, they attempted to contact my neighbors to enter on the fence line that runs along their driveway, even though I specifically requested for that not to happen. Ok...no big deal. It was caught and corrected ...but, annoying... since the neighbors are sometimes less than thrilled to assist in these matters.
When you replace a sewer line, they dig with a backhoe (fairly large piece of equipment) and remove huge piles of dirt, to trench out the portion of the yard where the line resides. Hyper Flow put down large sheets of plywood for the backhoe to drive over and that's to protect the lawn and your patio from getting destroyed. When they dig, it's normal for them to encounter sprinkler lines and you should expect those to be unceremoniously cut. I had, in total, 4 lines cut and was told several times that these would be repaired.
After all was said and done, $10k+ later, I have a new sewer line. When they removed their plywood sheets my flagstone patio was trashed along the edges. The edges were crushed by the weight of the backhoe. They said they'd come back and concrete it ...never did.
They said they'd re-attach/splice the sprinkler lines, and only 2 out of 4 were reattached. I went to turn on my sprinklers, end of April, and the backyard flooded. I also discovered that they removed a sprinkler riser and never replaced, and ruined connections to two others, because instead of unscrewing them at the risers, they pulled them apart (they don't pull apart). More gushers from those stations as well.
So, all tolled... the experience was less than stellar.
* Tech recommended Jetting when he should have probably noted the dip in the line from the outset - a more experienced tech would have and I would have foregone the jetting, saving the unnecessary expense. Instead I got offered some portion back after arguing the same.
* Patio was not properly protected and crushed - never repaired (I repaired)
* Sprinkler lines were not reconnected - this was probably the most annoying part, because you have to hand dig trenches, find the cut lines and repair ...or hire someone... more money. This is still pending, due to time constraints. I'd contact them to fix... but, a few months out now and still haven't heard back on the patio they were going to fix. So, why bother.
*Drip irrigation broken at 3 spots because someone confused screw fittings with compression fittings and just snapped 3/4 to 1/2 adapters at 3 riser locations.
* 1/2 irrigation riser removed at one station and never put back
I'm pretty easy going... but, now I'm kinda pissed at how much work this generated for me and I'm a busy guy. So... I'd say 3 stars, because the work was done... I don't have sewage coming up in the house, but not the greatest either, considering what I have left to clean up.
