Modern Logo Design for Option 1 Plumbing

I am starting a new plumbing business. I need a modern and minimalistic logo to represent my brand. Additionally, I would require a double-sided business card design and letterheads to complete my corporate identity.

The logo should embody the following:
- Modern and minimalistic design
- Uniqueness to stand out in the plumbing sector
- Professional and trustworthy appearance

For the branding materials:
- The business card design should be double-sided and reflect the logo
- The letterheads need to be clean and professional, using the logo subtly

Please note, the color scheme for the logo and branding materials hasn't been specified, hence creative freedom is open to the designer.
