What Your Neighbors Are Saying About Us

Jacob was fantastic to work with, as he was not pushy like the Anderson guy who used scare tactics, tried to upsell unnecessary add-ons, and even asked what our budget was. Jacob was very responsive and worked incredibly hard to accommodate our requests.

The installation was fast, just a day or two after the agreement was signed. The installation team was friendly, informative and skilled. They also discovered a leak in the vent seal and scheduled a roofer to take care of that. All in all this was a positive experience.

Ramon arrived right on time and was very professional. He knew exactly what needed to be done and explained it so I would understand why the old plumbing pipes were near the end of their life. He did a great job and was cheerful and very pleasant. I would highly recommend Thompson Plumbing and would definitely ask for Ramon again.

Called Thompson plumbing for an issue I had while changing out my shower valve. Thomas plumbing sent technician Jose Reyes within one hour. Jose promptly diagnosed the issue and gave me a reasonable quote. Once I accepted the quote he went to work and completed the job in a timely manner, Jose did a great job. Very satisfied

We had a great experience with Thompson Plumbing. Jose and Ignacio installed a tankless water heater, a whole house filter and replaced a whole bunch of old copper pipe. All around professionalism from booking the appointment to paying for the work. We now have a go to plumber here in Oceanside!

When Your Sump Pump Is Trying to Tell You Something

Sump pumps don’t always fail all at once. More often, they give you warning signs before a bigger problem develops. Catching those signs early can save you from a flooded basement or crawl space.

Here are some signs your sump pump may need repair:

Strange noises during operation
The pump runs constantly
The pump never turns on
Visible rust or corrosion
Foul odors from the pit
Water in the basement or crawl space
The pump vibrates excessively
Old age (7 or more years)

What Goes Wrong With Sump Pumps

Sump pumps are reliable machines, but they do have common failure points that can occur over time. One of the most common issues is a stuck or faulty float switch, which tells the pump when to turn on and off. When it fails, the pump may run nonstop or not run at all.

Motor burnout is another common problem, especially in pumps that have been working harder than usual during wet seasons. A burned-out motor means the pump simply won’t respond when water levels rise. Clogged intake screens and discharge lines can also reduce performance or cause the unit to fail.

In coastal areas like Oceanside, humidity and moisture exposure can accelerate wear on electrical components and lead to corrosion inside the pump housing. Power issues, a missing or damaged check valve, and an undersized pump for the home’s drainage needs are other problems our technicians encounter regularly.

How We Fix Sump Pump Problems

When you call Thompson Plumbing Heating and Air Conditioning, we send out a knowledgeable technician who comes fully equipped to diagnose and repair your sump pump the same day in most cases. We start with a thorough inspection of the pump, float switch, discharge line, check valve, and pit to get a complete picture of what’s going on.

From there, we walk you through what we found and what it will take to fix it before any work begins. Repairs may include replacing the float switch, clearing a clogged discharge line, repairing or replacing the check valve, or addressing electrical issues affecting pump performance. If the pump is beyond repair, we can recommend and install a reliable replacement that fits your home’s needs and your budget.

We also make sure the discharge line directs water well away from your foundation, which is especially important given Oceanside’s coastal soil conditions and how water can accumulate near home foundations after heavy rain.

Frequently Asked Questions

How do I know if my sump pump needs repair or replacement?

If your pump is under 7 years old and has a single issue, such as a failed float switch or a clogged line, repair is usually the right call. Older pumps or those with motor failure are often better candidates for replacement.

Why does my sump pump run constantly?

A pump that won’t shut off usually has a stuck or faulty float switch. It can also happen if the pump is undersized for the amount of water it needs to move, or if the check valve allows water to flow back into the pit.

How long does a sump pump typically last?

Most sump pumps last between 7 and 10 years with proper maintenance. Homes in coastal areas like Oceanside may see slightly shorter lifespans due to humidity and moisture exposure, which can affect internal components over time.

Is sump pump repair something I can do myself?

Some basic maintenance tasks, like cleaning the pit or testing the float, are manageable for handy homeowners. However, electrical issues, motor problems, and anything involving the discharge line or check valve are best left to a licensed plumber to avoid safety risks or worsening the problem.

What should I do if my sump pump fails during a storm?

If your pump fails while it’s raining, try to remove standing water with a wet vac if it’s safe to do so, and call Thompson Plumbing Heating and Air Conditioning right away for emergency service. Avoid entering a flooded area if there’s any risk of electrical exposure.
