What kind of hose connection is recommended?

Any available marine fitting with the right ID connection.

Which spares are suggested on board?

Normally a control panel and a pump are enough. Any case, keeping a kit of rubber hoses too will make it possible to reset a completely toilet. Inlet solenoid is normally a very reliable component.

What kind of tube has to be used?

Tecma macerator pump is able to discharge through any kind of tube (armovir, PVC, safe odor….). Check the diameter. Is it possible to flush into DN32, but this reduced section requires more power. Whenever is possible, use DN40.

Is frequently maintenance needed?

Tecma products do not need a specific maintenance or winterization. Any case, the usage of additives could be helpful (Thetford Tank Freshener) to maintain the discharge pipeline clean. This kind of product helps in avoiding odors and in flushing. It is safe for plastics and tubes. For inlet pump and solenoids, keep the strainers clean.

Is it possible to connect more toilets to the same line?

Yes. In this case a “Y” fitting is needed, in spite of “T” ones, to drive the flow to the tank. Always add a siphon break to prevent siphoning.

Cleaning

Ceramic is suitable for toilet application for the surface high level of hygiene. Use only non abrasive, non-petroleum products to clean the pump. Never use household cleaners,
which can contain bleach. Bleach, strong acid or petroleum-based products can cause irreversible damage to the rubber component of the macerator pump.

Tissue

Tecma is designed to process only toilet paper. Do not use other kind of tissue paper or kitchen paper towel. Thetford’s Aqua-Soft toilet paper is recommended.

Bad odors

If you have bad odours, be sure the smell is really coming out from the toilet. Sometimes the hot environment and the absence of usage could cause the drying of the water in the siphons of shower and sink (smaller than the toilet one). The siphon are used as “water traps”. Once they are dry, a direct connection for the air from the sewage and the bathroom is created. Then you have the bad odor. If the odor is from the toilet it means there is direct connection with the tank. Check that the system is designed properly and that, after use, the toilet remains isolated from the tank with a water trap.
