Hello,
I hope I’m asking in the right place.
We have a problem with our newly built house: our 7000-liter (about 1850-gallon) cistern is always empty.
Even after two days of rain, there is so little water inside that the pump can’t push it up.
Considering the pitched roof has an area of 200m² (about 2150 sq ft), it should collect a significant amount of rainwater.
Our neighbors with cisterns all have water.
Where could the water be going?
If the downspouts were clogged, they would overflow.
The cistern is made of concrete and was installed as one single piece.
What ideas do you have?

To my knowledge, there are "switch valves" that can be installed inside the downpipe to direct the water either into the sewer system or alternatively into a cistern. Maybe it’s just a simple adjustment?

Bautraum20188 Jun 2020 21:40So, all the gutters lead into the cistern. When you pour water in, you can hear it in the pipe. They are connected in front of the house, where a pipe runs into the cistern beneath the parking space. The screen is clean, and the leaf catchers are too. You’re right, the water is escaping somewhere. The architect will inform the company, and then everything will probably have to be checked, if necessary with a camera inspection. It remains exciting. Thanks for the help!
