Signs You Need Service Now
Don't wait for a flood. If you notice any of these, your water heater needs a licensed plumber today.
No Hot Water
Total loss of heat usually means a failed heating element, pilot, or thermostat.
Leaking Tank
Water around the base is a critical sign of internal corrosion — act fast.
Rusty / Discolored Water
Brownish water suggests the anode rod has failed and the tank is rusting.
Rumbling & Popping
Sediment buildup at the bottom of the tank causes overheating and loud knocks.
Pooling at the Base
Standing water can mean a failed pressure relief valve or a breached tank wall.
Unit 10+ Years Old
Most tanks reach end of life after a decade — sooner in Simi Valley's hard water.

Real reviews from Simi Valley and Ventura County homeowners.
"My garbage disposal was backed up… I worked with Steve and omg the quickness and accuracy of his work is amazing. I literally am going to be calling him for all my plumbing needs. PS his handiwork saved me $130 on a new disposal."
"Rocko's plumbing is an excellent company. The fact they are family owned and run made a huge difference… Steve, the owner, came to my house twice and both times he dug right away to do the jobs. He was punctual, respectful and very professional. He was also thoughtful about doing a clean job. No mess left behind."
"Cameron and Austin of Rocko's plumbing came out the other day and helped us install a new toilet. The entire experience, from scheduling the job, to them showing up on time and ready to work was excellent! Without being asked they covered their work boots with soft booties… professional and personable. Highly recommend."
