Covina Pipe Descaling

Pipe Descaling.

Older cast iron drain pipes build up rust and mineral scale on the inside until the opening is a fraction of what it was. Descaling grinds that buildup away to restore flow and can give a sound pipe more years of service.

The only plumber we will call

A fair price and a really easy company to work with. I’ve lived in my house for 10 years and have used 3 plumbers. This is the only plumbing company I will work with again.

Fixed leak same day

Flash Plumbing Inc took my job on the same day! I had a leaking toilet upstairs that threatened to damage the ceiling downstairs. The guys arrived and fixed the issue! Will definitely use them in the future.

Honest assessment & quality work

I’ve used Flash twice: once for a major operation to replace some shower pipes and once for a simple kitchen sink clog. In both cases, they were great! Responsive, same day service, and honest assessment of my options. Fast and high quality work.

Excellent job, respectful team

Flash Plumbing Inc did an excellent job! They swapped out the 40-gallon tank for a new tankless heater. The entire time, they were professional, courteous, and respectful. They left the area cleaner than when they started.

Daniel & crew are great

Daniel and crew were great, taking the time to get my 50-gal water heater installed right and now looks great with working shut off values!
