Why does Thetford Marine/ Tecma only offer ID 38mm (1.5″) Hose?
Tecma standard discharge connection is ID 38. More hose diameter will follow in the short term for potential alternative applications.
When should I replace the sanitation hoses?
That may depend. To check, you can rub the hose with a damp, clean cloth, then sniff the cloth. If it has picked up an odor, the hose is getting permeable and you will never eliminate the odor until you replace the hoses. Tecma HosePlus has an extreme low permeability with 5 year warranty.
Could I use chemical detergents /deodorants in the hoses or they can get damaged?
Just 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.
What kind of hose connection is recommended?
Any available marine fitting with the right ID connection.
How long is the warranty regarding odor permeation for the HosePlus 38?
5 years (longest time in the market) thanks to the high quality butyl rubber with extreme low permeation.
What are the warranty conditions for the HoseHelix 38?
No extra-ordinary warranty period on PVC hoses.
May I heat the hose to help it bend?
Never heat a hose to make it bend tighter than it wants bend willingly. Tecma Hoses are already extremely flexible (see bending radius specifications) and shall not require much efforts to get installed.
Does it make sense to replace only one sanitation hose line or shall I replace all at the same time?
In case of replacement, it is highly recommended to replace all : Hose to pump out, hose to macerator, vent line, etc).
