Water heater maintenance
for Inland Empire hard water.

Our Inland Empire hard water is tough on water heaters and quietly shortens their life. A little annual care goes a long way: a tank flush, anode rod check, and T&P valve test help yours last longer, and our thorough 14-point inspection covers every critical component so small issues get caught early. Have a tankless unit? We service and descale those too.

Freddie and his crew were very professional respectful kind and understanding. I had my mobile home completely repiped and did little extra for me. Now I am set in My forever home knowing I have new and good pipes and water heater. I can not thank you enough.

The company was responsive and professional. Jerry, their representative showed up on time, gave us a detailed quote and installation. I would recommend this company and this tech to others needing a water heater installed.
