Struvite is a material composed of magnesium, ammonium, and phosphate that creates stones (much like kidney stones) inside the holding tank. This mineralized build up can cause sensor misreading’s, become very heavy and weigh down your tank. Sometimes even separating the tank from the plumbing.

​

•Struvite is a problem in waste holding tanks, particularly after anaerobic digesters release ammonium and phosphate from waste materials.

•Struvite forms when there is a 1:1:1 ratio of magnesium, ammonia, and phosphate in the holding tank. (Improper methylation and its unhealthy)

•The magnesium comes from the drinking water

•Ammonia is broken down from the urine in wastewater, and phosphate found in foods, soaps, detergents and chemicals.

​

Struvite is a crystal formation on critical surfaces. It can block the flow of fluids draining from the black tank. Draining the tank or rinsing the tank alone will not prevent this from occurring.

​

A hydro-jetter is needed to safely break up the struvite and remove it from the tank. We highly reccomend a holding tank cleaning to remove and eliminate struvite growth.

Mold

Mold has no boundaries and will grow on the walls, ceilings and sensors of your RV holding tank. This is not something that can be removed by simply rinsing or back flushing your tank.

Mold only needs a few things to grow.

• Nutrients – Food

• A sustainable place - Dark

• Moisture – Damp

​​

Indoor mold grows very well when the indoor relative humidity rate is above 70%.  In Florida the average humidity rate is above 74.6% according to the University of Florida.

Draining the tank or rinsing the tank alone will not prevent this from occurring. Grey tanks do NOT have a back-flush system making it imperative to have your tanks professionally cleaned.

Sewer bugs AKA drain gnats

There are a variety of sewer bugs. The two most common are scientifically called psychoda alternate or psychoda cinerea. These can be found in RV holding tanks since they thrive on moist organic waste, especially solid waste!
Sewer bugs are born among decaying waste, sludge and mold. So, because of that, they have the capability to transmit diseases to humans.
While "sewer bugs" (AKA drain flies) lay eggs in masses of 30 to 100 per hour, which hatch into larvae within 30 to 48 hours. 

So how do you know if you have them? Well, you might see them in your shower, ventilation/skylight, or even around your sink where you keep your toothbrushes and face towels.
