I have been in my house for almost 2 years. It was build 1 year before I moved in. Lately I have noticed the water level maintained in the bowls of all 3 toilets is running a bit low. I have been wondering if there was an adjustment, but also odd that all 3 would lower like this. maybe cheap toilets..
Lately im begining to suspect more that I have a venting issue. I cought the toilet in the guest bathroom bubbling today! And it flushed slow. How can this be? The house is too new for the vent to be plugged? Plus tow of the bathrooms have sinks and shower in them. Each sink has one of those internal venting things on it too. Wouldn't this vent the toilet pipe?
Just trying to find out if I am reading too much in this. But now that I think about it, the toilets have all required frequent plunging too. But wouldnt they be vented seperately? Is there anyway I can look on my roof to know which is vented in what way? or perhaps the city knows?
