Shower Pump Troubleshooting

My pump has developed a leak, how can I resolve this?

Water around the pump doesn't always mean that the pump is leaking, sometimes the leak is from the pipes that are above the pump so check those first.

If the leak is coming from the pump then please contact our technical support team on 0191 516 2002 or email tech@salamanderpumps.co.uk

The pump is turning on and off. What could be wrong & how can I fix it?

This means that the pump is detecting a flow of water or a change of pressure in the system (depending on which type of pump you have) and this is causing the pump to activate.

If the pump has one of these:  then please refer to the question:

'The pump is making an intermittent noise. What could be the problem?'

If your pump doesn't have a pressure vessel and is turning on and off during use, this is most likely die to the amount of water coming into the pump not being enough to make the pump kick in.  Salamander pumps require 2 litres per minute per side to activate them so it might be that the flow is stopping and starting.

 

The pump is running but is not pumping any water

This is most likely to be caused by damage to the pump.  Please contact our technical team on 0191 516 2002 or email tech@salamanderpumps.co.uk for further advice.

The pump will not start. What can I do?

If your pump isn't starting, it's probably because:

  • There is not enough flow to start the pump (2 litres per minute flow of water per side is required)
  • The pump has installed incorrectly (water in and water out are the wrong way around)
  • There is no electricity to the pump
  • Debris in the filters to the pump, stopping the water flow
  • The pump is faulty

In order not to invalidate your warranty the only thing you can do is to check the fuse in the plug.  If that is OK, please contact our technical team on 0191 516 2002 or email tech@salamanderpumps.co.uk for further advice.

How do I deal with air in the system?

Air causes a range of problems in pumps and can ultimately damage or break the pump.  The best way to prevent air getting into the pump is to ensure that a flange is fitted on the hot water cylinder.  Salamander sell an 'S' flange, which is a device used to remove air intake from the hot water cylinder from where the pumps draws hot water.  The 'S' flange sits on top of the hot water cylinder and will need to be installed by a competent and trained installer.

Some of our pumps must have a flange fitted, please ensure that the pumps' warranty and installation guide book is checked before installation.

For further information on flanges please see the flanges section further down the FAQs.

The pump keeps blowing the fuse or tripping the breaker. What should I do?

Unfortunately, this usually means that the pump has seized.  Please contact our technical team on 0191 516 2002 or email tech@salamanderpumps.co.uk for further advice.

My shower works fine on one setting, such as hot or cold, but when mixed its pulses on and off. How can I resolve this?

This is usually down to the natural flow of water, either the hot or the cold supply of water is not generating enough flow to activate the individual flow switches.  Salamander Pumps require 2 litres per minute per side to switch on.

If this is a persistent problem it may mean that you need a universal pump.  You can upgrade your shower pump to a universal shower pump by contacting Salamander Pumps directly on: 0191 516 2002 or email tech@salamanderpumps.co.uk.

The pump is delaying in activation? What could be the cause of this?

If the pump is slow to switch on it could be because there is something restricting the flow of water.  This could be:

  • Blocked filters - these are found on the inlets to the shower pump
  • Shower head is partially blocked with limescale
  • Twisted hose to the shower head
  • Possibly the wrong pump has been installed.

 

There appears to be no or significantly reduced pressure to my shower. What can I do?

If the pump is activating but there is still low/no pressure to the shower this is likely to be caused by a restriction after the pump, this could be:

  • Blocked filters - these are found on the inlets to the pump
  • Shower head is partially blocked with limescale
  • Twisted hose to the shower head
  • Possibly the wrong pump has been installed
My pump remains on even when the shower is switched off. What could be the reason for this?

If your pump has one of these (pressure vessel):

 

Then the most likely cause for the pump running is that there is a leak somewhere in the system (like a dripping tap or shower, or slow pipework leak somewhere in the system.)

The easiest way to test if this is a pump issue or a leak, is to switch off water supply to the pump using the switches which are on the anti-vibration couplers (hoses) attached to the pump.  The diagram below should help:

                                        

If after the valve is in the off position (on both ends of the pump if it's a twin ended pump) the pump continues to run then it's a pump issue and you need to contact our technical desk either by calling 0191 516 2002 or emailing: tech@salamanderpupms.co.uk

If you pump doesn't have a pressure vessel then there may be an issue with the pump in which case please contact us using the details above.

Shower pumps and noise

The pump is very noisy. What could be the problem & how can I reduce the noise?

Salamander Pumps water pumps are designed for quiet, smooth running but there is no such thing as a silent pump.  If you are experiencing noise problems, then checking some of the things below might help:

• The anti-vibration feet supplied with the pump have been fitted - these are small soft rubber feet that fit on the base of the pump.
• The anti-vibration couplers (hoses) that connect the pump to the pipework are not bent or strained in any way.
• The pump isn't sitting on bare floor boarding or a shelf.
• The pipe work is secured to the wall and isn't pushing down on the pump.

If the pump is on the bare floor board, sitting it on a Salamander Pump may help reduce the noise/vibration.
 

How can I ensure that my shower pump is quiet?

Almost all of our shower pumps have been awarded the Quiet Mark, recognising that they are some of the quietest pumps available in the UK. However there are a few other things that you can do to ensure that your pump is as quiet as possible:

  • Install the pump a pump mat to reduce vibration.  Salamander sell a noise reducing pump mat, part number ACCPUMPMAT, available via our stockist network
  • Ensure that the anti-vibration feet supplied with most pumps are fitted - these are soft rubber feet that fit onto the base of the pump.
  • Keep the anti-vibration couplers (hoses) straight wherever possible and not bent more than 35°.
  • Make sure that the pipe work is secured to the wall.
  • Salamander sell an 'S' flange, which is a device used to remove air intake form the hot water cylinder from where the pump draws hot water.  The 'S' flange sits on top of the the hot water cylinder and will need to be installed by a competent and trained installer.  Air in the pump will make it noisier and more likely to damage the pump in the long run.

The pump is making a humming or buzzing noise. What could be the problem?

The most likely cause for a humming or buzzing noise is that the pump has seized.  This will probably be because of one of two things:

Hot water - The installation guidelines recommend that the temperature of the water going through the pump shouldn't be any higher than 65°C.  This is because some of the components within the pump can be damaged by hot water.

Air - Excessively hot water bubbles, and generates air.  Air can damage some of the components within the pump, particularly the impellers that drive the movement of the water.  If they aren't moving then the pump may seize and a humming noise will be heard.

The pump is making a gravelly or grinding noise. What could be the problem?

This is caused by a lot of air in the pump. If there isn't already one fitted, we would suggest that a flange is fitted to the hot water cylinder to prevent air getting into the pump and damaging it.  Salamander sell an 'S' flange, which is a device used to remove air intake from the hot water cylinder from where the pump draws hot water.  The 'S' flange sits on the top of the hot water cylinder and will need to be installed by a competent and trained installer.

The pump is making a rattling noise. What could be the problem?

If the pipework supplying the pump isn't secured properly, the vibrations from the pump may cause it to rattle.  Make sure that the pipework is clipped to a strong surface and that the pump is connected to the pipework using the supplied anti-vibration couplers (hoses.)  Keeping the anti-vibration couplers as straight as possible (bending no more than 35°) helps keep rattling noises to a minimum too.

The pump is making an intermittent noise. What could be the problem?

First of all, you need to identify if you have a 'negative head' pump or not.  The majority of negative head pumps are easily idenitified because they have a pressure vessel like the one shown below fitted to the pump:

If your pump has one of these then the most likely cause for the pump starting up on its own is that there is a leak somewhere in the system (this could be a dripping tap or shower, or a slow pipework leak somewhere in the plumbing system.)

 

The easiest way to test if this is a pump issue or a leak, is to switch off the water supply to the pump using the switches which are on the anti-vibration couplers (hoses) attached to the pump.  The diagram below should help:

 

Then leave the pump overnight.  If the pump doesn't start overnight then you probably have a leak in the system which is causing the pump to kick in.

WEEE Compliance

Are Salamander Pumps WEEE Compliant?

Yes...Salamander Pumps have been compliant since the 1st January 2019.

The WEEE Regulations 2013 (as amended), came into force from 1st January 2014.

Its primary purpose is the prevention of waste electrical and electronic equipment (WEEE) and requires the re-use, recycling and recovery of such waste, so as to reduce its disposal to landfill or incineration. All electrical and electronic waste must be stored, collected, treated, recycled and disposed of separately from other waste.

The products of Salamander Pumped Shower Systems came into scope of this directive on Jan 1st 2019. Salamander are committed to recycling and to the reduction of electrical waste and registered as an EEE producer under registration number WEEE/MM5397AA.

Disposal of Salamander products with the crossed out wheelie bin symbol.

Salamander fully endorses the environmental objectives of the WEEE Directive and electronic products are labelled with the wheelie bin symbol, to alert our customers to the fact these products should not be disposed of with general refuse, i.e. in a landfill site, or with household waste. All electronic products showing the wheelie bin symbol should sent to approved operators for safe disposal or recycling. 

Flanges

What is a flange?

When water is heated within a hot water cylinder, air bubbles form and collect around the side and top of the cylinder.  These bubbles (pockets of air) can be drawn into the pump causing it to be noisy and eventually damaging the pump.

A flange is fitted to stop the air from getting into the pump by making sure the water is drawn from further down the hot water cylinder, away from the air bubbles.  Salamander sell an 'S' flange, the 'S' flange sits on top of the hot water cylinder and will need to be installed by a competent and trained installer

Why is a flange so important?

Fitting a flange will prolong the life of a pump, and for the Salamander Right Pump range a flange is a requirement of the installation to ensure a valid warranty.

Flanges stop air getting into the water system.  Air in the system is called aeration and aeration can cause problems such as fluctuations in temperature, noisy pipework and in the case of the pump can lead to damage.

Which flange is the right for my installation?

There are various flanges available for a shower pump installation:

   

Surrey Flange (Salamander 'S' Flange

 

 

   

 

      Warix Flange

 

 

   

 Non-stop Essex Flange

 

 

Your installer should check the installation guidelines to make sure that the right flange is fitted.

The Surrey and Warix flanges are both top entry flanges, meaning that they screw onto the hot water connection on the dome of standard type hot water cylinder.

In comparison, the Non-Stop Essex flange is a side entry flange, which requires drilling into the side of the cylinder. This flange is best for when a pump needs to be situated above the hot water cylinder.
