Your questions
Toilet Repair questions.
Can a constantly running toilet be repaired?
Yes. Many running toilet problems are caused by worn or improperly operating components inside the tank. We inspect the toilet to determine what is causing the problem and recommend the appropriate repair.
Should I repair or replace my toilet?
That depends on the condition of the toilet, the type of problem and the cost of the repair. We can inspect the toilet and explain whether repair or replacement is the better option.
Why does my toilet keep running?
Running toilets are often related to components inside the tank, but the exact cause needs to be inspected.
Why does my toilet keep clogging?
Recurring clogs may involve the toilet itself, the nearby drain or a problem farther down the drainage system.
Can a leaking toilet damage the floor?
Yes. Water around the base or supply connection can affect surrounding materials if the leak continues.
When should a toilet be replaced instead of repaired?
Replacement may make sense when the fixture is damaged, repair options are limited or the overall condition does not justify further repair.
Do you serve homes outside Pittsburg?
Yes. Explore our service areas or contact our team about your property address.

We appreciated his expertise and his well-stocked truck so that the house and the sprinkler system flows were separate. He was polite and personable, made sure the system and the app worked for us, and cleaned up meticulously when his work was done.

I had an excellent experience with In Demand Plumbing, Heating & Air, especially Ezequiel and Donald. Ezequiel was professional, patient, knowledgeable and reassuring from the moment he arrived. I was dealing with a very stressful water-damage situation, and he took the time to listen as I explained what I had observed. He quickly identified the source of the problem—a broken toilet supply line upstairs that had caused significant water damage. He clearly explained what happened, completed the repair, restored the water and thoroughly tested everything to make sure there were no additional leaks. I especially appreciated Ezequiel’s communication and the time he took to discuss prevention, including recommending a Moen Flo system to help detect and mitigate potential water issues in the future. Donald, the HVAC technician, was also extremely helpful. He checked the HVAC system while they were there at no additional charge and made such a positive impression that I scheduled an appointment with him for next week to follow up on the system. Excellent customer service all around. Both Ezequiel and Donald made a stressful situation much easier to manage through their professionalism, knowledge and kindness. I would absolutely recommend In Demand Plumbing, Heating & Air.
