plumbing vents
Posted: Sat Jan 01, 2011 6:54 pm
Hi,
I'm having some trouble with the drains in a 1989 doublewide Fleetwood that we just bought. Poking around my plumbing and this forum I've found that all the sinks have the vents/checkvalves under the sink. There are two vents through the roof for each of the two bathrooms (sink and shower?). I have no idea how the washing machine vents. The drains are slow and they gurgle and will fill up and then suddenly release and drain. The washing machine is ok as far as we can tell, but even the toilets are affected somewhat.
As best I can make out, the roof stacks release sewer gas while the valves under the sinks admit air into the drain as the water flows down. Do I have that right? Is it reasonable that the problem could be caused by the checkvalves not working right? How are the toilets vented, do they tie into the pipes for the bathrooms out the roof? And what would I look for as far as the Washing machine goes?
A lot of questions, I know, but I'm trying to figure out how this system works! Any help is greatly appreciated!
Thanks,
Alison
