    Called at 930am. Plumber shows up at 1030am. honest + amazing + affordable. Person handling the phone deserve much praises too on picking up the phone within 2 rings, and manage to take down details quickly and assign the work order fast. Alvin ( sorry if I didn’t spell it right ), was great. came to my place, saw the issue, solved it without any hiccups.

    We discovered that our sump pump was running continously with smoke coming from it on Saturday afternoon. We had been flooded a year prior due to a power outage and our entire basement flooded ruining our finished basement so we were greatly concerned with it happening again. We reached out to Superior Plumbing and they were very quick to schedule us an appointment the same day. Sean arrived and was very professional and helpful from the beginning. He assessed our problem quickly, gave us our quote and installed our new sump within and hour and a half. He cleaned up after himself and set our minds to ease with our new pump. I cannot thank Sean and Superior enough for coming to the rescue on such short notice and I would happily recommend them to anyone with sump pump issues.

    Signs your sump pump is in need of repair

    Sump pumps are really great at stopping floods, but they are not as helpful if they stop pumping out water. What are the typical signs of sump pump failure, and how to handle them?

    • The float switch is jammed or broken. If the switch is jammed, release it manually. If it is broken, it should be replaced.
    • Non-working impeller. Sometimes debris can get through the screen and jam the impeller that pumps the water. To repair it, you must remove the pump from the sump.
    • The sump pump float is stuck. The sump pump float must move freely in order to function. Simply loosening the float should only result in a minimal service fee.
    • Sump pump is running but not building pressure. The most common reasons are clogged lines, impeller breakage, blockage of the float lever or simply the total failure of the sump pump. The only solution here is to replace the faulty part or the unit itself.

    At Superior Plumbing & Heating, we provide comprehensive sump pump troubleshooting and maintenance. With decades of experience, our certified plumbers can restore your sump pump to full working order in no time at all, so that you can rest easy!

    How much is a sump pump repair in London?

    Now that we have covered the most typical sump pump failures, you are probably curious about what the repair cost can be. And here, there may be a huge range! There are various factors that affect the cost of repair:

    • Type of your sump pump (the biggest factor, as submersible units, tend to be more costly to service than pedestal ones);
    • Old age and extensive rust build-up;
    • Regional differences;
    • Pump placing;
    • Floor type;
    • Material of your pump;
    • Professional or amateur repair.

    If you feel like a handyman and want to give the repair a try, then you only need to pay for the cost of the parts. However, your decision should be about more than just money. Attempting to repair a sump pump without prior experience or knowledge of how they work can be hazardous due to the risk of electric shock. Not to mention, poor quality repairs can further damage the pump, leading to more costly repairs. To get the job done right the first time, forgo DIY and call in the professionals.

    Superior Plumbing & Heating has straightforward pricing for repair labour. You will be aware of the repair cost before the plumbers proceed with any work – no hidden fees and surprises! For ultimate and transparent fix sump pump choose our proficient team!
