Am vazut ca WC-ul meu de la rulota THETFORD C-200 CW are un compartiment pentru 2 baterii AA care alimenteaza senzorul de nivel (g)
Mai este un sistem care ventileaza prin podea rezervorul colector cand acumuleaza presiune, probabil de la fermentatie la caldura se intampla asa ceva (j+k). Eu la acel sistem nu am vazut decat un arc si un dop cu garnitura, adica fix o supapa de presiune.
Intrebarea mea este, ventilatia prin podea se face natural sau mai exista un ventilator care sa fie alimentat la bateria rulotei? La bateriile AA nu vad din schema ca ar fi conectat si vreau sa stiu daca trebuie sa imi fac griji ca vor aparea mirosuri in rulota daca nu am curent in baterie.
