Inside of the Saniplus, Up is a high-tech pressure chamber which stops and starts with water movement, a motor, ultra powerful stainless steel macerator blades, and of course the pump. With Saniplus UP it is now easier for you to install brand new bathroom suites in any part of the house, without all the hassle of trying to fit a new plumbing system.

The Saniflo UP is manufactured by the UK's leading brand for macerators, they're domestic and commercial leaders, so you know that this is a product to trust, however in the very rare case that you do find that there is something wrong with the product, you're covered by a fantastic 5 year manufacturing guarantee, against any factory defects, just for that added peace of mind.

Saniflo Mind the Gap!

Mind The Gap!

Depending on the design of your toilet, older style macerator designs with the WC connection in the centre (like this Saniflo model) may push the cistern away from the wall far enough to leave a gap.

This can easily be resolved by the addition of a wooden batten between the wall and the cistern as shown.

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.

    Trouble with my very old Saniplus led me to buying a Saniplus up as I needed it in a hurry. It came very fast and very well packed next day at a good price as well. It is a direct replacement for my original so was easy to fit. The most difficult part was getting the toilet outlet rubber connector onto the Saniflo inlet. Its now just a stretchy rubber with no clamp. In use it is very much quieter than the original, especially when the shower is in use, it is difficult to hear it. When the toilet is flushed it is more noticeable but still quieter than the original. The new access port on the top will make life a lot easier for servicing and mean a lot less dismantling of the boxing in. All told very happy with the Plumworld service and the product.

    My old saniplus kept causing issues so I decided a replacement was necessary. This newer model fits perfectly, no issues with instalation. I got a plumber in to install. The electrics from the unit aren't a plug they are loose wires that need wiring which made the decision whether to call a plumber easier! The unit now works a dream. Water runs out the bath, tolilet and sink perfectly and ths the expected quiet noise when its running. Arrived quickly and was exactly what I required.

    5/ 5

    I have had many Saniflos over the years and they do their job efficiently and reliably. The Saniplus is excellent and easy to fit and provides a great solution to a tricky problem, this particular model is a big improvement over the one it replaced. Saniflo are not the cheapest but in my mind they are the best. Plumbwold as a supplier were excellent, v competitive price and excellent service so 6 GOLD STARS! Highly recommend product and supplier.

    Ordered this to replace an existing Saniflow which we purchased in July,2007 for our ensuite. Never a days trouble and boy does this get used. Shower, toilet, handbasin and bath. Thought about cheaper modules "but why' you want the most reliable then you buy a name that is recognised easy to install with no fuss. Instructions are clear and fool proof. Would I buy this product and recommended company again. Absouletly!!!

  • Markus H
    5/ 5

    Bought to replace an existing Saniflo unit which had packed in after more than 20 years. This is a new improved model but the dimensions are more or less the same as the old one so no need to modify the pipework thankfully. Seems quieter than the previous one and works just as well. Good price from Plumworld. Much cheaper than Screwfix or Wickes even. Quick delivery. Well recommended.

    I have had a saniflo unit for nearly 20years with no problems. As part of a bathroom refurbishment I purchased a new saniflo 6003 from Plumbworld. The price was reasonable and delivery was very prompt. The new unit fitted easily as it matched existing pipework. It works properly and is very much quieter than the old unit. Very pleased with the product and Plumbworlds service.

  • Andrew Cohen
    5/ 5

    I bought the new one to replace the old one that has been in service for around 20 years. The new version fitted perfectly (except for the outlet hose being half an inch shorter - so I re-used the old one) - and is quieter. Really good to have a new one again. Does a loo, basin and a shower, upstairs in an old thatched cottage (grade 2 listed). Brilliant.

  • Jeremy Joseph

    The Saniflo Saniplus Up was delivered within 1 day of my placing the order, with no extra charge for delivery. It was easy to track the package and determine the delivery time. The price quoted by Plumbworld was the cheapest I could find on the internet, and their service was excellent. The device was installed without a problem and is functioning perfectly.

  • Geoff Lambell
    5/ 5

    Having read your appraisal of the Saniflo Plus UP we decided to take a gamble and order it as our old macerator was so loud in operation that we dare not use that bathroom at night. Well we are delighted to report back that it has done what you claim. It is at least 48% quieter that the old one, what a relief ! thank you (very much ) Geoff & Lin Lambell

  • Gary
    5/ 5

    Have had the Saniplus in place for about 15 years before it gave up the ghost. This replaced perfectly (hardest part was getting the rubber waste in place - I recommend a can of silicone lube if it's a tight squeeze like ours. Does the job perfectly and a little quieter than the old one. Better design too with an inspection cap on top.

  • Headlessbear
    5/ 5

    This Saniflo replaced one which we had installed in our en suite bathroom over 10 years ago. Initial impressions are that it is much quieter than the model it replaced. Efficiently pumps the waste from bath,sink and toilet. We look forward to many years of good service. Price and delivery from Plumbworld was first class.

  • Robin Mair
    5/ 5

    This unit was purchased to replace a saniflow that was already there. All that had to be done was to change the wiring. However as it was just a self fit replacement I do not appear to be able to apply for the 3 years extended warranty. It is a great bit of kit and a lot quieter thatn the piece it replaced.

  • Ken
    5/ 5

    Excellent value and service. The Engineer told me I had made the right choice in selecting a Saniflo and the 6003 in particular. It has been working perfectly since its installation almost 2 years ago. In my house moves I have had several Saniflo's - the first in 1985!

  • Daniel Knight
    5/ 5

    Bought this as a replacement for an old Saniflo Plus system. This was very easy to install as I had the existing plumbing in place, but is also a lot quieter than the previous model I had. Also much easier to access the internal blades than the previous model

    Has been working in a very satisfactory fashion. I trust it will do so as long as the one which it replaced did, “ 15 years “ is certainly incredible. It was delivered as promised also. Thank you. H. R
