Not only do plumber apprentices have to complete their training and education to receive their licenses, they also are required to pass a criminal background check and carry liability insurance. Hiring just anybody can make you vulnerable to fraud since unlicensed plumbers might not know what they're doing or could pretend to fix something and end up charging you for the incomplete work.
I had a problem with my hot water heater. I called the local franchisee of MR. Rooter. My first mistake was that I didn't check the reviews. With a lot of bad reviews I would have known better and stayed away. That was my fault. I blame myself. 2 people came out to repair my water heater. I don't know why they would send 2 people but I should have realized that something was wrong. I showed them the water heater and within 10 seconds they started with "your water heater is old and it's not worth repairing"... Wait a second. I called for a repair and now they are trying to sell me a new water heater. They never even bothered to look at the heater or try to determine what's the matter. They never bothered to bend down and light it or try and do anything. They saw that it was 1 year past the warranted date and then went into selling mode.
I thought that my sump pump had ended its life and needed to be replaced. The contractor I found through Home Adviser came out the following day and arrived reasonably promptly. The technician tested the pump and it wasn't responding. He then checked the breaker panel and all seemed well. However he checked to see if power was reaching the outlet, it wasn't so he tripped some breakers and reset them and the power to my pump came on and the pump works so a replacement wasn't necessary. He charged $75.00 which I think was reasonable for a call-out fee and time spent.
They did come out on Easter Sunday for an emergency blockage (house full of people) but I should have asked how much. Charged $498 to clear 25 feet of sewer line, which I was told was flat rate whether it was ten feet or a hundred feet. No mention of emergency service. At least they came within a few hours and got the job done. Here’s a hint- if you have an older system and have visitors from the city make sure you know what they are flushing!
Sometimes a faucet leak can be stopped by replacing the rubber washer at the end of a faucet stem or cartridge. This is a more common repair on older fixtures when things were built to last and designed to be able to be maintained. Other times the whole stem or cartridge needs replacement or the bibb seat deeper back into the fixture needs replacement. That leads to matching up the right components and often times making a trip to the hardware store or plumbing supply house necessary due to the many varieties, makes and models of faucets. My advice is to make sure your Plumber has faucet repair kit on their truck before having them come out to assess the issue.
