What Our Clients Say About Us in San Jose
Had the plumber Daniel come to my condo today for a clogged toilet. He spent almost two hours snaking with a camera my drain and pulled out a huge clog of tree roots. He knew exactly what he was doing and did a wonderful job. I would recommend this company very much.
Ron K.
Great, reliable, and timely service at a reasonable price. I shopped around quite a bit before landing on CPI. Their rates were competitive, they responded promptly, and their plumber fixed a few issues quickly and without much fuss. I’ll definitely be calling them again the next time we have issues!
Allan Huynh
CPI Service was sent to my home by my condominium association. They agreed to a very early morning appointment and the gentleman arrived exactly on time. He went through the problem very methodically to see where the problem was. Something that no one else could figure out was taken care of in half an hour. I would very definitely recommend them.

FAQs – Toilet Installations, Repairs & Replacement in San Jose

Is it cheaper to replace a toilet than repair it?
In some cases, replacing a toilet can be more cost-effective than repairing it, especially if your current toilet is old, inefficient, or requires frequent repairs. While repairs are usually cheaper upfront, constant maintenance can add up over time. CPI Service can help assess whether toilet replacement is a more economical long-term solution.

How to repair a running toilet?
If your toilet is running constantly, the most likely cause is a worn-out flapper or misadjusted float.

CPI Service can handle this repair efficiently, ensuring your toilet functions properly and conserves water.
How Long Does a Toilet Installation Take?
The typical toilet installation takes about 2 to 4 hours, depending on factors like the complexity of the installation and whether there are any issues with the existing plumbing. CPI Service in San Jose ensures a fast and efficient installation while providing quality service to meet your needs.
