15 - 750 Word Articles About Plumbing

I am looking for 15 well written articles relating to plumbers, DIY plumbing projects and drain cleaning. I will provide a list of the 15 topics after acceptance. The writer must be a native English speaker who speaks English as their first language. That is a firm requirement, articles just don't make sense if you write in a language other than your first (you wouldn't want me to write in Hindi). The articles should be at least 750 words in length and fully proofread and be free of all grammatical and spelling errors. The articles also must be original and will be Copyscape checked, any articles that do not pass Copyscape will be rejected. To show that you understand what I'm asking and that you've read the project please suggest a topic or two with your bid that you think would be relevant to write about for this job.
