Garden Grove Plumber Who Knows the City’s Older Homes
By William “Jay” Horsky Jr., Owner, Professional Plumbing, Inc. · Published June 25, 2026 · Updated June 25, 2026
The kitchen drain backs up again a week after you last cleared it, and a Garden Grove plumber who knows the city’s older homes can tell you why it keeps happening. Professional Plumbing has served Garden Grove since 1985, covering West Garden Grove, the Historic Main Street district, and the mid-century tracts off Brookhurst and Harbor. Most homes here date to the 1950s and 1960s and run on some of the hardest water in the area, and the old pipe underneath tells the story.
Key points for Garden Grove homes
- A drain that backs up a week after clearing tells a Garden Grove plumber the pipe itself is failing, not that you need more chemicals.
- Most homes date to the 1950s and 1960s, where original cast iron drains rust and pit until they choke a line.
- Some of the hardest water in the area, around 16 to 18 grains per gallon, speeds the wear.
- We cover West Garden Grove, the Historic Main Street district, and the mid-century tracts off Brookhurst and Harbor.
What we see in Garden Grove homes
Garden Grove water is very hard, around 16 to 18 grains per gallon, and most homes date to the 1950s and 1960s. Behind the walls, original cast iron drains rust and pit until they choke a line, which is why a drain that keeps backing up a week after clearing is usually telling you the pipe itself is failing, not that you need more chemicals.
We open the wall, show you what is there, and give you the full price in writing before any work begins, with a free second opinion on major work. We have worked these older tracts for decades.

Garden Grove plumber FAQ
Why does my kitchen drain keep backing up?
On older Garden Grove homes the original cast iron drain rusts and pits nearly closed, so it backs up again soon after clearing. Replacing the failed section with ABS ends the cycle.
Do you replace cast iron pipe?
We do replace cast iron pipe. We open the wall, remove the corroded cast iron, and install new ABS joined with no-hub couplings that will not corrode the same way.
How hard is Garden Grove water?
Around 16 to 18 grains per gallon, among the hardest in the area, which wears fixtures and seizes the old shut-off valves in these homes.
Do you handle slab leaks in the Knott-area tracts?
We handle slab leaks in the Knott-area tracts. The mid-century slab homes around Valley View and Knott are where slab leaks turn up, and we locate and repair or reroute them.
Are you available after hours?
We are available after hours, 24 hours a day, every day, usually within one to two hours.

“Chris is a top-notch professional. Everything about my repair was better than I expected. I noticed the leak right at end of day, worried that I'd have to wait until tomorrow. But Chris saved the day! His work was quick, efficient, and left the area cleaner than when he started. Along the way he gave me advice about my water heater. A total class act! I'm going to specifically ask for Chris in the future. Thank you!”
