Report
A&A Plumbing, Sunnyvale, installed my new toilet. Mike, the owner was polite and professional. Perfect installation and he took away the 27-year-old toilet. Mike was friendly and offered a tip or two for maximizing the functioning of the toilet. The only less than ideal thing was, due to employee illness, they had to cancel a prior appointment. On that prior day I waited for their arrival, but they never came.
I even called three times, left 3 voicemails, but never heard back. If you decide to hire A&A Plumbing, I recommend that you check their website to get a discount that is available (as of January 2022) if the client pays other than with a credit card. It saved me $20. A&A Plumbing is located in Sunnyvale near Wolfe and Fremont.

Before using A&A, be sure to get a price quote in advance, especially for small projects. My project took less than an hour and I was charged about *double* the average hourly rate. In my case, I was told afterward it was a flat rate price. Learn from my mistake and get a quote. If no quote is provided, go elsewhere as there are many competent plumbers with reasonable rates.

Mike is transparent, fair and trustworthy in his under promise over deliver workmanship. He will point out if a competitor is overbidding or incorrectly diagnosing a problem. His team creatively solved a drain mainline issue without having to replace the entire line. Highly recommend but almost don't want to because too many will fill up his calendar :-
