strainer

Yes it dose'nt matter vertical or horizontal.

One of the things to consider is what happens when there is no flow. Does the strained debris fall back down the pipe and mangle the components in a pump the next time it is started, for example?

Just because something could be done doesn't mean that it should be done......

I agree with Ducon.

Anyway I think our guest has the minimum amount of common sense to install the Y type strainer in the correct position. Even in horizontal piping you can install it with the non-alineated leg in the upper side!!!!

Ancient romans said "numerus stultorum infinitus est" and transfinite numbers theory wasn't developped by Kantor at that time.

"Even in horizontal piping you can install it with the non-alienated leg in the upper side!!!!"

I agree yours that Y-strainer can be installed in a vertical or horizontal position, but at horizontal position the non-alienated leg can not be oriented in the upper side, it must be at lower side.

Because of that I used the word "can" and not "must". Obviously, you "can" but you must not. And for the same reason I give some credit to the intelligence of our guest. I'm tired of seeing how some CR4 people treat guests as if they were stupid.

Thank u very much every body for your positive response.

i give a thought about the position, i think the position is depends to the flow, if the flow is going down, it is applicable. but if a vertical pipe line with upward flow, then the y strainer is not suitable there.is it right?
