FAQ

Help! My toilet fills so slowly.

Slow-to-fill tanks are the result of the toilets’ fill valves having restricted flow, caused by sediment in the domestic water distribution pipe.

Brock Mechanical did an outstanding job on our 3,000-square-foot new construction home. This was a large, highly customized project with unique fixtures and a custom tub, and their team handled every challenge that came up. They went above and beyond, stayed late when needed, and made sure the job got done right. Their ability to find solutions and deliver such great work made a real difference. I’d highly recommend Brock Mechanical to anyone looking for a team that takes pride in what they do.

 Trustindex verifies that the original source of the review is Google. had some well water pressure tank and valve pump on/off issues issues.  Called Brock and owner attempted to walk me through a do-it-yourself fix.  So he was willing to pass up a money making opportunity to have me fix it myself.  Thankfully I have zero plumbing skills and hired them on the spot (how can you not hire someone who is trying to help you avoid their help?).  Glad I did as issues were way beyond the average handy man (which I am not) skills.  Bill and Austin created a state of the art fix to a problem that has been nagging me for years.  I am sleeping well tonight with no water worries.  Don't hesitate to hire them!!!

 Trustindex verifies that the original source of the review is Google. They did an excellent job fixing our main sewer line in the basement that’s went into the basement wall.  It was creating a mess for us. Their team came in and fixed it to perfection!  They were clean, efficient, and extremely affordable!  We are incredibly grateful!

 Trustindex verifies that the original source of the review is Google. Good work installing a Bradford White power vent gas hot water heater after my AO Smith was leaking.  And thanks for installing the pressure tank too.  After watching the install, that is not a DIY project!, at least not for the vast majority of people.  Was a good looking install.  And Doug got me scheduled fast.  Easy, prompt communication.
