5.3

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.
5.4

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.
5.5

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.
5.6

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
install a ventilated siphon on the line. The Flexi 2G and Design line is equipped with a
ventilation valve - integrated in the internal discharge hose - which, in most cases, replaces
the siphon behind the bulkhead.
5.7

Do I have to install a ventilation duct for the integrated ventilation valve?

It is not necessary to connect the integrated ventilation valve with a ventilation duct.
In any case it is possible to do it following the best practices for the ventilation ducts.
