Forum Title: water from loft tank is returned to main line
Hi, my apartment is at level 3. Previously I have had Non return valve (check valve?) installed which restricted water going out from loft tank.The area I live at has hard water conditions which damages Non return valve frequently. So I thought to have U tube from main line (High loop ) Ironically, physics principles dont allowing this to work and water from loft tank is getting drained to main line (siphoned?). The piping inside is like seen in images,The plumber has installed vent pipe also, but it didn't worked out. is there solution to this problem? I seek help from members in this forum points to note, 1)I want to skip vent pipe manual switching on/off, as when I am out & water is available in main line it would come out of vent pipe (what is air release & vaccum insert valve? will it do?) what is optimum location of vent pipe & height & size ? 2) the input & output of loft tank is given to single point to have water circulated in my apartment, so that i can use loft tank/main line water in kitchen/toilets (etc)

the check valve needs to be rotated so that it is level once the ck valve is level. it will keep the water from leaving the tank IF IT is installed correctly with the arrow pointed in the direction of flow and level not real sure what else you are trying to do, but the ck is the reason water is coming back others may have different ideas

picture of the new installed ck valve. i see a climpse of it. and I THINK you have a swing check installed as a spring ck. swing ck can only be installed on a plumb/level horizonital line. it ck gate, works by gravity , it swings spring ck, can be installed both vertical/horiz. it uses a spring

As even if this check not works loft will be filled by both direction(from top & from bottom) Right? The issue is when I am not at home,when I come back I see the tank is drained,I have verified that level below apartment gets this returned water.(The high loop didn't worked out ) Also,I don't to wish to involve any type of check valve because of the corrosion issue due to hard water. How to make high loop outside work as i desired/thought.
