FAQ's - Aeration

Q: What are the advantages to a linear pump?
A: Linear pumps are easy to install and very quiet.

Q: Are rotary vane compressors always louder than linear pumps?
A: Yes, rotary vane compressors are much louder than linear air pumps.

Q: My rotary vane compressor seems to only last a year or two, is this common?
A: Rotary vane compressors are very reliable and should last you quite a few years with proper servicing of the system. Check filters, airline, and diffusers for dirt or obstructions.

Q: Can I replace my vane compressor with the linear pumps?
A: Yes, commonly done and with little difficulty. But some states and local laws require replacement with identical product. (Check your state and local regulations.)

Q: Why are there two models of the FA340?
A: The FA340 are made as replacement models for 2 major brand s of aerators that have 2 different size concrete openings. The FA340 J fits in the 10" concrete opening and the FA340 N fits in the 12" concrete opening. See Illustration.

Q: My breaker keeps blowing with my aerator unit, what is causing this?
A: The most common problem is debris wrapped around the shaft putting a high amperage load on the motor. For this reason it is a must to have the FA340 aerator on a 4-amp breaker or the motor will burn up in high amps situations. Remove unit from tank and lay the shaft on the ground (be careful not to bend shaft), check shaft for debris. Also check rubber vibration dampers on mounting brackets. Worn dampers mean shaft is out of balance and putting undue wear on the motor bearings causing premature replacement of the unit.

FAQ's - Effluent Pumps

Q: How do I find a replacement for my sump and sewage pump?
A: The easiest way would be to get all the information off the mfg. label before ordering a pump. If this information is not available, sizing will have to be done. It is very important to size a pump for proper operation of your system. A wrong pump can cause system damage and backup into the building, etc.

Q: What is the difference between an effluent pump and a sewage pump?
A: An effluent pump is for the removal of pretreated liquid waste discharge from an onsite sewage treatment system. A sewage pump is for the removal of wastewater solids of up to 2" diameter depending on size of pump.

Q: Do I need to drill the 3/16" vent hole?
A: If a check valve is being used we recommend drilling a vent hole. This hole is located in the basin between the pump and check valve usually a few inches above the pump "on" level but below the pit cover. The vent hole will prevent air locking from occurring (pumps runs but will not remove fluid from tank or basin).

Q: Do I need a check valve?
A: In a sewage system a check valve is required to prevent the sewage from draining back to the basin. They are recommended for all other submersible pump systems.

Q: I have to shake the discharge pipe to get it to run. What's wrong?
A: If you have an automatic unit with an integral float switch, the switch assembly is malfunctioning and the switch, switch arm, and case gasket should be replaced. The average switch life is 4-7 years but may be higher or lower depending on the application. If you have a nonautomatic pump with a variable level float, it may be hung up on something or needs to be replaced.

Q: Does the Qwik Jon have any odors?
A: If properly installed per the detailed instructions provided with the system there will be no odors.
