We had 2 technicians out to address several issues: the water heater, a humming sound when the air kicks on, our water filtration system, a clogged toilet, and a sewer smell in the half-bath. The first guy came out to address our specific problems. He told us the following: the water heater can wait but eventually you'll have to replace it because it's leaking. The humming sound is from your electronic air filters and those are crappy so just don't even use them. Don't even turn your water filtration system on, the water here is fine. Use drano and an auger on your toilet. The sewer smell is probably a clog, use some more drano. He left and didn't actually fix anything. I wrote a check for $287 and everything was in the exact condition when he left as when he arrived. Two weeks later, another technician is out for maintenance visit and I ask him about all issues above. He tells me that the water heater needs to be replaced immediately and will go any day now, the humming is happening because the unit is not sitting on rubber, it's directly on the floor, the water here is bad and we should get the filtration system working asap, the clogged toilet is either the vents or the pipes, and the sewer smell is either a valve or a leaking pipe. His visit was prepaid as part of a package but again, everything was in the same state before and after his visit. What concerns me the most isn't that neither technician really did any work, or the money I paid them for minimal service, it's that they gave me such different diagnoses for the plumbing issues; each with varying timelines and costs. Who do I believe? And how do I proceed? Well, I don't trust Wahl so I'll be calling Steve Poremski and Knechtel Plumbing...whoever calls me back first will get my next check.
