Depending on the space conditions, sometimes you can create an open ended standpipe away from the tank (where there is more space and its easier to maintain) where you mount the float control away from the the actual valve and the tank. That way you can have the float mechanismm where it is easy to get to and the valve it controls in another location where it is easier to get to. The tank could be outside in the ground. Wherever you have the tank, it is the tank's filled surface elevation that drives whether or not this setup is possible. The CLA-VAL can have its float mounted distant from the valve. Note that these sensing type valves require the water pressure on the sensing lines to be at least a certain value to keep the valve closed. If you have the break tank because there is low pressure when drawing water, then the sensing line pressure might drop below the minimum value under certain conditions. The valve would appear as if it is not closing all the way. You can avoid that situation by connecting the sense line to the higher pressure side of your system instead of the incoming water side as is the factory default.
