How to enter repipe on rental property

We had a leak and had to do a repipe on our rental property which was around 18K  after repipe and asbestos remediation, etc. Since over 2500, I must take it as an asset depreciation over time. When I try to set it up, the options for this 'asset' are: 

1. residential rental real estate

2. Appliance, carpet, furntiture

3. Land improvements

 

None of those quite makes sense to me. Thinking number one, but I used that to put the rental property as an 'asset' two years ago. Recommendations on what to do please?

 

Thanks,

Adam
