Old Water Sump


Excess Water
With fresh water being continuously added throughout the day, excess water needs to be removed as well.  In the row of under tank sumps opposite the fresh water addition point is an overflow that drains via gravity into a simple Rubbermaid container housing an automatic sump pump.  The sump pump is connected to the house drainage system through 1 1/2 inch plumbing.  In addition there is a one way check valve installed to prevent house waste water from siphoning back into the sump.  In the sump you can see several coils of copper pipe.  This is part of the fresh water reservoir feed line.  Cold water passes through these coils hopefully absorbing some of the waste water s heat and conserving energy.  A larger coil could be used to better do the job.  Two 2 inch PVC ball valves can be seen in the picture.  The one all the way to the right drains from the bottom if the filter emptying it into the sump.  The one in the left upper middle is in series with the backwash line of the filter and is opened when the blower is operated so that the house waste system is not pressurized :)


Additional Drains
Two additional access points are placed in the 2 inch PVC drain line in the hatchery room.  One at the end of each aisle.  These are attachment points for a 1 inch siphon hose used to vacuum the bottom of the tanks.  The dehumidifier also drains into this line.  The lower PVC line drains the under tank sumps back to the pump.
A couple of angels have made their way into the sump and were able to avoid getting sucked into the pump.  They have grown pretty well and don't seem affected by the dirty water even when the tanks are vacuumed out.  Shadows of two can be seen in the upper corners of the upper picture.
