Side Valve on slurry tank.

[meekers]

Evening. I am planning on putting a 6” draw off point on the bottom of a slurry tank I have, the contours of the ground means I can dig it out without too much hassle. I realise I should have done this when I built it- but I didn’t! So my questions are: How will I core a 12” reinforced wall? I’m guessing it’s a specialist contractor job. And once this is done where will I get a tank connector for the side? Will I just have to fabricate something? It would be handier if it could all be done from the outside for obvious reasons. The bottom draw off point on my tower has a pipe on the inside with a 90 degree bend on it facing down- do you think I will need something like this. Any help much appreciated!
Thanks

Why not leave the bottom of the tank wall alone and fit an 10" syphon pipe ending in a 6 inch coupler. Could be left empty when not being used so doing away with the chance of accidental tank emptying and you would notch a hole at the top of the tank wall.

I do believe that any valve in the side of a store needs 2 valves 1 meter apart for safety

Need to seek advice about this from someone in the know, gate values need to be doubled up and secure etc.

Do you think with this method I would lose some of the pressure of the slurry with the viscosity of it going up and down a 6” pipe?

That's why I would use a 10" pipe, to cancel out losses due to friction. A 6" pipe wouldn't be as good but would still be better than sucking.
