Operating a T-Pump against a Closed Valve is Operator Error

Typical symptoms of thisoperator error are:• Inverted duckbill valves.
• Circuit breaker popping.
• Damage to the pump motor.

31730123173024*Inverted duckbill valves are almost
always caused by (improperly) closed

Revision Date: Jan 2013

• Analog Vacuum Gauge(P/N 318530002)

Training 2013 Service

Determine the System Leak Rate
Use SeaLand’s Digital Vacuum
Gauge (P/N 318530003) to confirm
the system leak rate and find theleak.

Digital gauge measures vacuumin 1/100 Hg in.
Reads 10-hour leak rate in
15 minutes!

1. Be sure that water has circulated through thesystem and the duckbill valves are wet. Turn
off water to toilet.
2. Follow the instructions included with thevacuum gauge to determine the leak rate.

Locating Odor Source

Revision Date: Jan 2013

Training 2013 Service

Locating Odor Source• Less than half of the reported odor failure
installations are toilet system related!
• Your nose knows!
• Follow procedure in CWNB No. 5.
Available at www.dometicsanitation.com

Revision Date: Jan 2013

Training 2013 Service

Detecting Permeated Hose
• Go aboard boat just before searching for failed
hose so that your nose is not desensitized.
• Wipe all sanitation hoses, including the holdingtank vent hose with a paper towel. Smell the
towel for waste odor. Do not smell the hose
directly. This will desensitized your nose.
• Use a new paper towel for each hose.
• The permeated hose will transfer the odor to thepaper towel.
Revision Date: Jan 2013

Training 2013 Service

Nature of Microbial Malodor• Untreated wastewater is an ideal microbiological medium.
• High BOD of untreated wastewater provides a strongly
anaerobic environment.
• Anaerobic fermentation can produce very strong acids andother very malodorous compounds.

(BOD is the amount of oxygen used by microorganisms to decay.)(Anaerobic is the absence of free oxygen.)

Revision Date: Jan 2013

Training 2013 Service

Major Causes of Malodor:
Malodor Cause:
Not toilet system related.

Improper materials
selected.

Possible Sources:
Frequently malodors are from source other than toilet or holdingtank. For example:
AC or Refrigerator Condensate Drains
Fuel System Leaks
Vinyl Adhesives
Shower or Sink Traps and Sumps
Improper holding tank materials, such as aluminum, stainless steel or
flexible.
Using non-odor resistant hose in runs with standing sewage.

Improper system layout.

Not including a vent filter in the holding tank vent line.
Installing wye valve in a fashion which causes sewage to be retained inunused hose run.
Mounting holding tank at other than lowest point in the system.
Connecting hose to bottom of holding tank side wall.

Improper installation
technique.

Keeping hose runs and overall layout as simple as possible.
Fasteners from blind side of bulkhead penetrating sanitation hose.
Low points in vent hose which form traps.

Improper usage.
Revision Date: Jan 2013

Incorrect piping connections, such as loosing threaded fittings whileturning hose on fitting at opposite end.
Allowing waste to remain in holding tank for very long period, i.e.
over the winter.

Confirm that
hose hasfailed byrubbing witha clean clothor papertowel. Whenodortransfers tocloth, failure
is confirmed
