Q & A
-
I want to install the Topargee monitor before the pump? Will this still work
It is possible although you may get some ghost readings, this is when water moves past the sender but not actually exiting through a tap. A stop valve before the sender can stop the water from moving.
-
Can I install the Topagee before the pump?
Yes this is possible, but you might get ghost readings. Ghost readings are possible when water moves past the sender without exiting. The loose water is common with installation before the pump and even with some installation after pump where the sender unit has a long section where the water often moves when travelling or when the van moves (someone walking in van) A stop valve before the sender will stop the water moving.
-
The manual talks about pin holes causing reading issues? What does this mean?
Pin holes are caused by accidental damage to the pipe. It allows air or water in or out. This can cause inaccurate readings and repairing or replacing the pipe will lead to more accurate readings.
-
What are pin holes in reference to when talking water plumbing in a caravan?
Pin holes can happen by accident, it is simple a gap that might let air or water in/out, they can also cause ghost readings as the air moves down or upstream depending on the angle of the pipe. These can be patched up, replacing the damaged pipe is the best solution

Excellent product. Easy to install. It's so good to actually know how much water is in the tanks rather than the standard caravan useless indicators.
