Why is the compost too wet in my Sun-Mar Lawn and Garden Equipment?
- K
  Kimberly MckenzieAug 15, 2025
  To address compost that is too wet in your Sun-Mar Lawn and Garden Equipment, immediately improve porosity by adding about 3-4 gallons of wood shavings (except cedar) to the drum. For ongoing maintenance, switch to Compost Sure Blue or 100% wood shavings as your bulking material. This is because poor compost porosity, often due to excessive peat moss, compacts the compost, hinders liquid drainage, and restricts oxygen flow.

  Andrew BondAug 18, 2025
  If the room where your Sun-Mar Lawn and Garden Equipment is located is airtight: * Hold a lighter up to the air intake holes on the back of the unit. Air should be drawn into the holes. If not, check the venting for too many bends or horizontal lengths. * Provide more ventilation to the room. * Install fresh air intakes on any competing appliances.

  If the vent stack of your Sun-Mar Lawn and Garden Equipment has too many bends or horizontal lengths: 1. Re-install the vent stack to reduce the number of bends or eliminate horizontal lengths. 2. If straightening isn't possible, remove the fan assembly and reduce recirculating air by covering the area between the fan exhaust and the 90-degree vent intake elbow with duct tape or similar material.

  To resolve compost that is too dry in your Sun-Mar Lawn and Garden Equipment, add 1/2 to 1 gallon of hot water to the compost to reach the appropriate moisture level. This issue often occurs when moisture isn't added regularly or when the toilet isn't used for urination.

  Re-install the vent of your Sun-Mar Lawn and Garden Equipment to eliminate low points where condensate can accumulate. If re-installation isn't feasible, drill a small hole at the bottom of the low point (preferably outdoors) to allow condensate to drain.

  If a device other than a Sun-Mar diffuser is installed on top of the vent stack of your Sun-Mar Lawn and Garden Equipment, replace it with a Sun-Mar diffuser. Wind turbines or vent caps can impede air movement.
