FAQ & Quick guides

The Felton Oxijet is a water saving shower attachment that changes the characteristics of your shower when compared to traditional flow restrictors. While saving water, it gives a luxurious showering experience.

The Oxijet utilise the venturi effect, jetting the water through 4 micro nozzles. This increases the water speed dragging air through the coloured baffles. This air volumizes the water stream, forming small bubbles that burst when they touch your skin.

If you have a shower handpiece, use the Oxijet with yellow baffles. 

If you have a fixed rose with a female thread, use the Oxijet with pink baffles. 

If you have a fixed rose with a male thread, use the Oxijet with blue baffles.  

If you have mains pressure (over 300 kPa/3 Bar), and a non-restrictive handpiece/fixed rose, the Oxijet should work for you.

The Oxijet will NOT work if you have any of the following:

• Low flow electric shower
• Low or unequal water pressures
• A restrictive handpiece/fixed rose.

It is made from DR Brass, which is machined, and then chrome plated. The baffles are made from silicon rubber.

A restrictive handpiece/fixed rose is one that has a flow restrictor or flow saving device fitted to it that can't be removed.

Some handpieces and fixed roses have flow restrictors which can be removed. These will work with the Oxijet, but the restrictors must be removed first.

If your Oxijet is installed so that waterflow follows the direction of the arrow and yet water is leaking out the baffles there are two potential causes:

• Your handpiece or fixed rose may contain a flow restrictor. If it is removable please take it out. If it is not, you may have a restrictive handpiece/rose and the Oxijet will not work for you.
• The water may appear to be coming from the baffles, the actual leak may be caused by the Oxijet not sealing on the hose/stem's rubber washer. We've made the threads on the Oxijet longer than most fittings. They will work but it may not fit every shower in the market. Please check that the washer is installed correctly in the hose/stem, and that the Oxijet is tightened firmly.

Note: even though water may be coming out of the inlet baffles, the Oxijet will still be working. Compare the difference in spray appearance with it fitted to without is fitted.

This is normal, and is part of the self-draining function of the Oxijet. A common observation is that when showers are turned off, water left in the rose/handpiece may drip for some minutes before draining. A handpiece/rose fitted with an Oxijet will drain almost immediately.

This is normal. Small droplets of water may escape due to the turbulence created by the jets within the Oxijet.

This is normal. While the baffles reduce the noise of the air entering the stream, the noise of air exiting your handpiece or rose is not preventable, and is simply a sign that the Oxijet is performing well.

If the flow through the Oxijet is too low to provide an adequate shower, there are three potential causes:

• You may not have mains pressure, and your pressures are most likely below 300kPa, and therefore the Oxijet is not suitable.
   
• You may have a flow restrictor somewhere in the system. For a fixed rose, please check within the stem. For a handpiece, at both ends of the hose (including the wall elbow).
   
• If neither of the previous situations apply to you, it is most likely that you have a restrictive handpiece, and therefore the Oxijet is not suitable for use.

The flow resistance through the Oxijet will create extra pressure within your shower hose. We recommend only EN1113 rated shower hoses are suitable for use with Oxijet. There are some shower hoses supplied into the Australian market that do not meet this quality standard, and these may leak under increased pressure. Replace with a standard approved hose.

If you're unsure what your pressure system is, try the Thumb Test as a rough guide:

• If you can hold your thumb over the outlet of the tap while it is fully turned on (either hot or cold), it is most definitely low pressure. Be careful not to scald yourself when checking the hot supply. Always check with your plumber to confirm.

REASON FOR BLOCKAGE:

• Limescale/calcification build up
• Foreign matter/debris

SOLUTION:

• If there is a build-up of limescale - remove with a fingernail or a soft brush
• Foreign matter/debris - some shower heads and handpieces can be dismantled for cleaning however most cannot. Please call us and we can confirm if cleaning is possible. We recommend a suitable filter is installed in all domestic and commercial situations to protect the entire property.

If cleaning is required follow the steps below.

For the shower head:

• Remove shower rose from the shower head stem.
• Use equal parts vinegar and hot water 1:1. Place the shower rose in the solution for between 15 - 20mins
• (Note: the face of the shower rose cannot be removed for cleaning purposes.)

 For the handpiece:

• Use equal parts vinegar and hot water 1:1. Soak the handpiece with the nozzles facing down.
• Wait 10 - 15 minutes and clean handpiece with soft microfiber cloth.

This method is usually sufficient to clean the shower heads and handpieces. If extra cleaning is still required use a soft brush.

WELS is an acronym for the Water Efficiency Labelling Scheme. It is a national New Zealand regulation established by the Ministry for Environment, compulsory for suppliers of certain water using/dispensing devices, including taps and showers, as a water usage rating system. It allows consumers to make decisions to conserve water and money by comparing the water efficiency between different products. The WELS labelling scheme provides a national standardised star rating system from 0 to 6 stars. The less star rating a product has, the less water efficient it is.

WaterMark™ is a product performance certification mark owned by the ABCB (Australian Building Codes Board). It is designed to show compliance to and that the product has been tested to specific standards for product quality, performance. This includes that the products won't contaminate water. It is an independently verified assurance scheme to show that it is fit for purpose. Felton products complies with WaterMark requirements, although it is not compulsory to have Watermark in New Zealand.

Think of your shower mixer as the main engine – it supplies the right mix of flow and temperature to all the other shower components. Selecting a mixer that best matches your pressure system and needs is a crucial step to getting the best performance out of your shower. If you are unsure what your water pressure situation is, please speak to a plumber.

Unequal Pressure:  
Your cold supply comes directly in from the mains or town supply or a large supply tank installed with a pump to increase pressure, but your hot supply comes from a low pressure hot water system.

If you are currently on an unequal pressure system but you are considering upgrading to a mains/equal high pressure system in the future then we would recommend our Fusion Plus Shower Mixer.

Single Lever – Fusion Plus Shower Mixer
Diverter Mixer – Versadisc Diverter Mixer
Integrated shower head – Feltonmix Unequal Pressure Shower Mixer

Equal Low Pressure:
Both your hot and cold water supply are from the same source at low pressure e.g. cylinder, ceiling tank, a tank on an outside stand or a tank elevated on a hillside. You have an equal mix of hot and cold water with a low pressure flow rate. We would recommend our equal pressures mixer for the best performance.

If you are planning to upgrade to a mains pressure/equal high pressure system in the future, Fusion Plus will be the best option as this can be upgraded from the front of the wall without touching the wall lining.

Single Lever – Fusion Plus Shower Mixer, MP/EP/Flexidisc Shower Mixer
Diverter Mixer – Versadisc Diverter Mixer
Integrated shower head – Feltonmix Equal Low Pressure Shower Mixer

Mains Pressure:

This is the ideal pressure situation, for more information on the technology, you can check it out here.

If you’re after a compact look, consider the 35mm cartridge options (up to 500kPa) in our  Tate, Max, Jaz and Willo II ranges.
For pressures of 500kPa or more, consider the Fusion Plus, Versadisc or an integrated diverter option.

1. Get your plumber to check the inline filters of the mixer as these can sometimes get blocked.
2. If you have unequal pressure or low pressure – check to see if a flow restrictor or aerator is installed. If so, this can generally be removed.
3. If you have a Fusion Plus shower mixer take a look at the FAQ section for this mixer here

Check the outlet (handpiece/shower rose) for a restrictor. If you’re on mains pressure this should have been inserted when installed.

1. Determine what shower mixer you have, check out “Which shower mixer do I have?” in the FAQ section.
2. Please contact Felton on 0800 743 358 and we can advise if the mixer you have installed is suitable for the pressure situation.

A dripping shower mixer could be caused by a few different things.
When the mixer is in the ‘off’ position, there will be water in the plumbing and the shower system that needs to drain out.
Under some circumstances it may take some time for this draining to cease and this may be exacerbated if you have a low-aperture showerhead or limescale build-up as it may take time (up to a minute or so) if water becomes air-locked in the system.

If you know what shower mixer you have, check out our innovations page for more information and for spare parts. Please get a plumber to check if any seals need replacing. If they do, take a picture of your shower mixer and email your query to technical@felton.co.nz and we can assist further.

When the mixer is set to ‘off’ there will be water in the plumbing and the shower system that needs to drain out.

Under some circumstances it may take some time for this draining to cease and this may be exacerbated if you have a low-aperture showerhead or limescale build-up as it may take time (up to a minute or so) if water becomes air-locked in the system.

1. Remove the showerhead. If the leaking continues this might indicate an issue with the mixer and you may consider replacing it with a new one.

2. If dripping when turned ‘off’, inspect the rotor and seals for damage.

3. If the leaking stops, then this might indicate an issue with the showerhead. Start with cleaning the showerhead and replacing the seals. If cleaning doesn’t solve this issue then it may need to be replaced. You can see the spare parts here.

If the leak doesn’t stop, follow the Feltonmix General Guide here.

Remove the showerhead and the handle. If the leaking continues this might indicate an issue with the mixer and you may consider replacing it with a new one.

If dripping from handle during operation only – replace the o-rings on the rotor.

Some of the nozzles on your showerhead might be blocked from limescale build up. Please clean your showerhead using these steps:

Grab your handy Feltonmix Toolmate, twist the face of the shower head and ensure parts are pushed in fully home with 2 clicks! Now test your shower head.

How to service the Venturi mixer:

Exposed:
To open the valve, use either long-nosed pliers or the purpose-made universal spanner tool (supplied with Designer II roses and wallsets) and pull out the rotor.

Concealed:
Remove the nut and remove rotor.

VENTURI ROTOR INSTALLATION
1. Replace both hot and cold inlet seals with seals supplied.
2. For equal low/equal high-pressure systems ensure that a green rotor set is fitted.
3. For unequal pressure systems ensure that a white rotor set is fitted.
4. The enclosed silicone grease pack is for use on the O ring and rotor seal surface.

No, the Rotor and Cam sets come with a seal kit.

Unlikely, the Venturi shower mixer was sold from 2002 – 2010 and had a 5 year warranty.

Yes, parts are still available for the Venturi mixer, which was sold from 2002 to 2010. Two configurations were available – with the outlet concealed or exposed, but unfortunately both had the tendency to seize. O-ring grease helps to lubricate the o-rings on the rotor. Due to the closing action of the rotor over time, the o-ring lube will remove itself from the o-ring causing the rotor to become stiff and possibly seize.

The alternative jet (4 spanner flats) has a smaller venturi, allowing less cold water and therefore greater temperature control at high cold pressures. The standard venturi jet has 2 spanner flats and is factory fitted if you have unequal pressure.

Please measure the diameter of the barrel. It should be either 55mm (2014-Current) or 60mm (pre-2014) in diameter.

We introduced 2x brass Venturi jets early in 2017. Before this, only the standard Venturi jet was offered. The 3-notch alternative jet has a smaller venturi, allowing less cold water and therefore greater temperature control at high cold pressures.
