Can you drain a salt water pool into your yard?

We generally don't recommend draining your pool, but if it needs to be drained for a liner replacement or other service, salt pools can be drained into your yard without causing the damage that a traditionally chlorinated pool would cause.

I don’t see why not.

However, most plants cannot tolerate high levels of salt, so you may wind up killing your lawn or other local vegetation.

Additional answer: yes, it is safe to drain a salt water pool into the ground. Refer to posts on draining a pool in general before you attempt this. The concentration of salt in a salt water pool is slightly saline, at about 2700-3400ppm as opposed to the ocean which is at 35000ppm.

Certain plants/animals can obviously tolerate salt water better than others, so you may have some issues, but in general the levels should be low enough not to cause too many problems.
