F.A.Q.
6.1
Is it possible to connect several toilets to the same line?
Yes. In
this case use “Y” connections instead of “T” connections. Always use vent valves. Fit
a proper pipe system based on the number of toilets used.
6.2
What kind of maintenance is required?
TECMA products do not need special maintenance or winterisation.
It is however suggested periodically and in preparation for the winter of:
•
Perform maintenance of the solenoid valve and / or intake pump filters.
•
Perform rinsing cycles with clean water.
•
Completely empty all the systems to prevent the pipes from freezing or use a specific
antifreeze product.
Do not use automotive antifreeze products or products used in the windscreen washer
solvent tank.
Comply with the environmental protection standards in force when choosing and using these
products.
We recommend cleaning the tanks and pipes with Thetford Tank Freshener.
6.3
Is it possible to use acid or aggressive products?
Plastic components of the TECMA toilet have been tested with several marketed cleaning
products. Avoid using products such as vinegar, acetone, trichlorethylene. Avoid using
solvents so as not to affect the rubber components. Moreover, avoid using gel and foams in
order not to obstruct the vent valves. Do not dispose of harmful substances into the sea.
6.4
What kind of tube must be used?
The TECMA macerator pump uses any type of pipes (armovin, PVC, safeodor) to discharge.
We always recommend using a DN 40 pipe.
6.5
Which spare parts should I keep on board?
Besides a control panel, a motor, and the solenoid valve, we recommend keeping a sleeve kit
to completely regenerate the toilet.
6.6
Do I have to install a ventilated siphon behind the toilet bulkhead?
In case of non-centralized systems (sea water) with toilet installed below the waterline it is
mandatory to install a ventilated siphon sufficiently higher than that. The exact height must
be determined according to the maximum boat heeling angle.
For any system with long discharge pipes and risk of siphoning, it is always recommended to
