Make Sure your Septic Tank is Full

This is a common problem that can be easily fixed. The tank can become clogged if there is too much waste. This could cause unpleasant odors to linger inside and out. This problem is unlikely to occur if your septic tank gets pumped regularly by a professional.

It is essential to keep your wastewater system clean and sanitary. We recommend that you schedule a pumping service if your tank has not been serviced in a while. This will allow your technician to evaluate the tank and address any problems.

Make Sure you Have your P-Traps and Floor Drains Checked

A dried-out P-Trap, or floor drain can cause sewer gas smells. Each plumbing fixture contains a trap (or P-Trap) that prevents sewer gas entering the home. They can leak gas into your pipes if they are empty or dry out. This is avoided by running water through your floor drains, bathtubs, or sinks every few months.

Check Your Roof Vents

The plumbing vent stacks allow drains vent air through the roof. Gravity is used to move liquid and solid waste through the plumbing pipes. The vents then equalize the pressure throughout the waste process.

If the waste has difficulty pushing air through the pipes and out of the way, it won't flow correctly. Vent pipes are connected to all drain and waste lines at the top and run up the roof. This allows for equalization of the air pressure. Venting allows air to flow into the waste pipes and connects to the water piping system.

If a plumbing roof vent stack fails to function properly, it can cause unpleasant smells, gurgling sounds in the toilet and sometimes slow drains.

Venting pipes can also be affected by high winds. Sewer odors can be caused by downwind drafts. It could be that your vents are not functioning correctly if you see water bouncing around in your toilet. You may need to raise the vent stack by adding to existing pipes. This can be done by a waste management professional.

Make sure that your vents do not become blocked by leaves, snow, ice, bird nests or landscaping debris. You can either remove the blockage yourself or hire a professional.

Carbon Activated Cover

A carbon activated cover can be used to eliminate strong and unwelcome odors from your septic tank. Simply place the filter on top of your vent. It will do all the work.

Activated carbon is a better option than charcoal for eliminating the smell. This device is great for eliminating odors and preventing future problems.

Septic Tank Enzymes

Septic tank enzymes can be used to remove odors and increase bacteria growth in your tank. The majority of septic tank enzymes that are used to control odors contain powerful waste digestion material and essential nutrients, which is good for your tank.

The enzyme will separate the organic material and make water-soluble nutrients. The bacteria will then digest the nutrients and multiply to make more enzymes. This will ensure that the tank is clean in both anaerobic and aerobic conditions.
