5 Saniflo Problems and How To Fix Them

You may not need to replace an old Saniflo unit. Below are five common problems associated with Saniflo brand macerators and some quick tips on how you can fix them.



The Saniflo Is Giving Off a Terrible Smell !

Bad smells can be due to a build-up of limescale and human waste in the 2-3 inches of water that’s always left in the Saniflo. Other Macerator brands have self-cleaning technology, but Saniflo’s need to be descaled regularly. If you’ve never descaled your macerator then you may have to do this a few times to clear the smell.


Electric Shock Risk

The Saniflo Keeps Tripping The Electrics

If your Saniflo is tripping the electrics, it usually means that water is getting into it and leads to the circuit shutting off to avoid any other damages, or there’s a loose wire. Always make sure the electrics are off before you inspect the pump. If there’s an issue with the motor seal, then call a certified Saniflo engineer to repair it. If the motor is worn or faulty, this unfortunately means that you’ll have to purchase a new macerator.



Saniflo Leaks During Operation

One reason for your Saniflo leaking from the vent could be that there is a big build up of waste inside which will have to be manually removed.

It’s also possible that the motor is nearing the end of its life and can’t work as hard as it used to. This would mean the whole macerator should be replaced.

The rubber waste outlet could have shrunk because of too much toilet cleaner. If water is spraying out the vent, you will need to replace the rubber waste outlet.


Saniflo Starting on its Own

The Saniflo Starts On its Own!

There could be a few reasons as to why your pump keeps starting on its own throughout the day and night: (Excluding the possibility of a ghost!)

The microswitch is misfiring because it keeps thinking the tank is full – you will have to manually remove the waste between the switch and the tank floor and then reset the pump. If the rubber membrane is damaged, waste can then get into the switch and cause a problem. In this case, you will have to purchase a new rubber membrane and switch.



Saniflo Vibrates & Buzzes Loudly

If when flushing the toilet you hear a horrible vibrating noise, there’s probably something that has been lodged in the macerator blade. Turn off the Saniflo and remove the lid. If you see an obstruction straight away, remove it. If the foreign object is in the blade you can remove it using small pliers.

    This was a replacement for our old Saniflo Sanislim which was about 11-12 years old and getting a bit noisy. So, whilst decorating the en-suite, it seemed like a good to replace it. After searching online, Plumbworld seemed to offering the best price, so I purchased a new Sanislim, which I have to say fitted in perfectly and is much quieter than its predecessor. I am very happy with my purchase and coupled with the excellent and rapid delivery service I am well pleased. Thank you.

  • Andy
    5/ 5

    My trusted Saniflo engineer advised we needed a new unit after the old one conked our after about 10 years Service. Apparently Saniflo had redesigned the standard unit so it was a few millimetres bigger in places and so would not fit the bespoke housing we have. So we needed to get the new slimline model. So far so good but check back in 10 years time. Saniflo why tinker with the size? Crazy

  • Michael Thomas
    5/ 5

    Excellent fast service and very reasonable price from Plumbworld for this Saniflo item which is essential for a toilet and bathroom where the waste has to be pumped away. Although this unit is smaller than the standard size, (we did not have enough space for a full size Macerater), it still copes easily with a large cistern full of water, and the toilet waste, easily and quietly.

  • Senior Lady
    5/ 5

    I have had a Sanislim fitted recently to service a small vanity basin and a toilet in a closet on the ground floor. I am about to have a knee operation and stairs to the first floor bathroom could present a hazard throughout the day. The Sanislim works perfectly with little noise. Better for visitors also. I wish I had done this sooner.

  • Justin
    5/ 5

    It is a sanislim by Saniflo so let's not get too excited, but it has replaced a 14 year old saniflo, and it is brilliant, it sits quietly in the wall and is barely audible in comparison to the old one. They are not cheap so I had some reservations, but not any more. worth every penny.

  • Bill Baker
    5/ 5

    I ordered the macerator one day and it was delivered damage-free the very next day, and all at a superb price. I will definitely be using Plumbworld again. Cant fault the service, plus your sales guy Micheal McCaffrey couldn't have been more helpful. Many thanks

    A great peice of kit neatly tucks behind wc and a great deal quieter than previously used models . Simple to connect to with shower/ bath wc and basin . The pump clears very quickly ideal during night time use with no prolonged pumping to disturb others

  • Robert Waller
    5/ 5

    This was a replacement for the original fitted 15 years ago. Plumbworld were the only retailer with this in stock, and it was the cheapest of all the online retailers, so definitely will be using Plumbworld again.

  • Duncan Bailey
    5/ 5

    An good product although previous experience with two identical macerators tells me that they do not have long lives. This makes it essential not to have to pay the high prices demanded by other suppliers.

  • Alistair Duffy

    A well packaged good quality macerator that was straight forward to install. It comes with all the necessary parts to configure to your plumbing setup. First class piece of kit.

    Excellent product again, all required fittings included. Quiet operation and ideal for those tight spaces. Personally, I would only fit Saniflo macerators.

  • Pat Rogers
    5/ 5

    I always do a search for the best price on products and Plumbworld always come out cheapest on this product. Delivery is quick as well. Can’t fault them

  • Humeyo

    Premium price for a premium product. Worth paying for peace of mind given that replacing a cheap macerator would cost more than the price of this one.

    Like-for-like swap with the 15 year old model that had finally run out of pumping power. Plumber had no issues swapping it over. Perfect! Very happy.
