Yes - Would buy this items again!!
We are replacing the existing pump we have with this exact same pump. It finally gave out after working for us for the past 15+ years. We have it in ground in our backyard to help pump out excess water that accumulates in the yard during "flash flooding" to help avoid our yard debris getting pushed into our swimming pool.
