Battery ventilation is vital â summary . There are no legally enforceable (RV) standards in this area. This article can thus only state that battery makers stress battery ventilation is vital. Some explain why. There is little or no risk if batteries are housed in well vented enclosures. With sealed batteries the risk is not high.

Sometimes, itâs just not feasible to vent only the sink, maybe because a shower or tub is sitting too far away, or maybe because one fixtureâs drainpipe does not connect to the main bathroom drainpipe, which is usually the line running from the commode. When this occurs, an additional vent is necessary. In new construction, the plumber will install a separate vent for any plumbing fixture that does not use the vanity vent. If a fixture has its own vent line, the line will run vertically to the attic and tie into the vent-and-soil stack if possible.
