thanks for all the replies about the backwater installation location.
Either most plumbers around here only use a flapper valve (or check valve as I have read) or I have not found one who uses the other kinds mentioned.
What kind of backwater valve do you use and which is the most fool-proof
and offers an easy way to get to and clean in case of a backup ?
Since it has been said that I need to be able to access the valve to clean it, I am confused because my plumber told me that I should never open it because the pressure build up in it will create 20 ft spout of sewage. It seemed a little odd to me that there would be so much pressure, but what do I know. Is there some special way of opening the thing and cleaning it ?
My local plumbing supply house only carries an Oatey backwater valve, which seems to me the check valve kind.
Is there any backwater valve you would swear by ?
