Fix Apartment Plumbing and Fans

I need a skilled handyman to address several issues in my apartment:

1. **Leaking Kitchen Sink Hose**
- The hose is leaking from the connection to the sink, causing water to pour out whenever I use it.

2. **Kitchen Fan Direction**
- The kitchen fan is currently set up to push air away instead of pulling it in. The exact issue needs to be determined on-site, as the client skipped a question regarding the main issue.

3. **Bathroom Fan Malfunction**
- The bathroom fan in the main area is constantly running, even when the switch is turned off.

4. **Toilet Issue**
- The master bedroom toilet is continuously running due to a problem with the suction valve inside.

Ideal skills and experience:
- Plumbing repair
- Electrical work
- Handyman experience
- Attention to detail

Please provide a comprehensive solution for all issues.
