"Sunday night tenant calls sewer backing up in her bathtub
made several calls no answer 4th call spengler plumbing answered (dispatcher) referred me to service man
Serviceman called back I explain the circumstance's to him he states he needs 125.00$ to come to house
I gave him my credit card he charges the 125,00$ then proceeds with a sales pitch about how much cheaper a monthly fee for
their service would be, I declined.
Serviceman arrives looks over situation calls me back states it will be 701.00 to clear sewer line that has a outside house access
Tenants can not use toliets or showers serviceman is aware of the situation I am in and I tell him to proceed 
His total labor time was about an hour
will never use them again

"I just pay $75 you never know who's going to come out. They do everything electrical. Just about everything is covered except the septic tank. I had an air conditioner replaced. It went great, all I had to do was pay for the freon. He didn't charge e more than what was needed."

"when I got home from work I smelled a strong odor of gas. I called Reeds 24hr Plumbing & Drain and the lady that I spoke with on the phone said she would get a technician to call me back immediately. within minutes I was contacted and the gentleman told me what to do to get the gas shut off till he arrived. I was really surprised that he said he was in the area and would be here with-in 1hr or less. He showed up in less then 30 min. He was very nice and located the leak very quickly. I was given a price before he did any work and he told me  exactly what the problem was and what he was going to do to fix it.. It took him a little less then an hour and was clean, courteous and  friendly. As he was going over the bill he asked me if I ever served in the military? I not only was pleased with this technician  but I was given a 10% discount for serving our country. Thank you Reeds plumbing for doing a great job and your prices were reasonable and to me even seemed very low. I will use your company again and recommend you to my friends and family!"

Septic Tanks FAQs, answered by experts

Age is certainly a factor in well pump failure. The older your pump, the more likely it is to fail. 

Beyond age, other factors can cause your well pump to fail, too. Things like poor water quality can cause sediment buildup in your pump. Without proper cleaning, your pump can seize up and fail. Having a dry well for too long can also cause your pump to fail, as it keeps working even though there's no water for it to pull. 

Normally, when your well pump turns on or off, you’ll hear a small click. This isn’t anything to worry about, but it can be a problem if it’s clicking continuously. This can indicate that the well pump is short cycling—the pump continuously turns on and off.

This can wear out the motor and provide uneven water flow. If this happens, you may need to get it looked at by a well pump professional to see if you need to repair the switch or pump.

Soda, coffee, and other soft drinks are highly acidic. This affects the pH in septic tanks, causing them to require more frequent pumping. However, a vast majority of people don't need to worry about septic system disruption. Pouring out the occasional flat soda doesn’t affect septic systems to the same degree as the high-volume dumping from restaurants and convenience stores.

A septic system inspection costs $100 to $200. Doing so can spot issues early so you can plan for necessary repairs ahead of time and save yourself the issue of a backed-up septic tank. Some septic tank repair professionals do an inspection as part of their yearly maintenance on your septic tank if you choose to pay for that service, but you should shoot to have a septic system inspection completed at least once every two to five years.

There are a couple of ways you can determine the depth of your well. One method is to use a device called a well sounder. This tool has a long measuring tape containing a sensor to alert you once the end reaches the water. 

Or you can DIY it by using a long tape measure with a half-filled bottle of water attached to it. Lower the tape measure into your well. Once you feel tension on the tape, you’ll know the bottle has reached your static water level. This will give you an approximate idea of your well’s depth.
