I have a flooring job coming up and I want to take advantage of the opportunity to install a sump pump under my house. Occasionally, it rains enough that water stands in the crawl space, hence the pump.
1. Can the pump's exhaust water be plumbed into the sewer drain (unmetered) without risk of the water coming back into the drains for the bathtubs, sinks, dishwasher, etc?
2. Is a local shutoff switch required and/or typical if using a float valve? If so, what type is typically used?
3. How deep below the surface should the pump be placed? (french drain style)
