"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

Septic drain fields should be at least 10 feet from the property line, though exact requirements vary by location. Some areas may require further distances, such as 25 feet or more, depending on soil conditions and local health regulations. This extension ensures proper wastewater absorption and prevents contamination of neighboring homes.

A well pressure tank typically lasts between 5 and 15 years. However, its lifespan can be influenced by several factors. High-quality, appropriately sized tanks tend to last longer, with some top-of-the-line models lasting up to 30 years. Regular annual maintenance, including inspections, cleaning, and prompt repairs, is crucial for extending the tank's life. Water quality also plays a significant role; water with high levels of sediment, minerals, or rocks can cause premature wear. Overworking an undersized tank can also limit its lifespan.

You should pump your septic tank once every two to four years for a family of four, depending on your septic tank size. You should pump a 1,000-gallon septic tank every two years, while a 1,500-gallon tank should be pumped every four years. Water usage also affects how often you should pump your septic tank. If you notice slow drains, foul smells, or gurgling sounds from your drains, you should pump your septic tank as soon as possible.

A septic alarm can sound different depending on your system, but often, it’s a loud, repetitive beeping noise or a steady, high-pitched noise. It may also be a loud buzzing noise. To confirm the noise is your septic alarm, check your alarm box for a red light. You can also silence your alarm with a red button or switch on the box. Look for something that says “Test” or “Mute.”

The best times of year to pump or empty a septic tank are spring and fall. Many professionals recommend spring because the ground has thawed, making the tank easier to access, and any snowmelt or rainfall can aid in proper drainage. Pumping before summer is also ideal to avoid conflicts with vacations or outdoor gatherings.

Fall is another great option, as contractors may be less busy than in the spring. Servicing the tank in late fall or early spring can also reduce the risk of overflow from extra precipitation during winter and spring.

While summer is a possibility, winter is generally not recommended. The ground is often frozen, which can make it difficult to access the tank, and the waste inside may also be frozen.
