Frequently Asked Questions
Do your softeners require any servicing or maintainance?
Unlike many softeners that require an expensive maintainance visit on a regular basis, our units do not require any servicing. This is because of our commitment to quality control.
How much does it cost?
The price of a water softener will vary depending on the plumbing in your home, your water usage, the water hardness in your area etc. etc.
Please contact us, and one of our representatives will make a quick visit to your home in order to assess your needs and provide you with an accurate quotation.
Please be aware that your quotation visit is completely free of charge and puts you under no obligation.
What are the dimensions of the twin cylinder Dualflo unit?
The Dualflo water softener is very compact, thanks to its unique twin cylinder design. The overall dimensions are:
Height 490mm 19 2/8 in
Depth 460mm 18 1/8 in
Width (Cabinet only) 212mm 8 3/8 in
Width (including connections) 267mm 10 1/2 in
In some installations an outside cabinet can be used to house the softener. The softener sits sideways in the cabinet and as such the dimensions are:
Height 550mm 21 11/16 in
Depth 330mm 31 in
Width 625mm 24 5/8 in
Our installers all work in house and are therefore capable of dealing with more complex installations. To find out what options are possible in your home, please book a demonstration today.
Why does the salt dissolve in the way it does?
The salt block sits in 10 mm of water. Before a regeneration starts, that water is saturated with salt. After the regeneration the brine is replaced with fresh water which then dissolves more salt from sides at the bottom of the block.
The brine is heavier than water so as the fresh water touches the side of the salt, it dissolves and forms brine, which sinks to the bottom. The fresh supply of unsaturated water is therefore at the top and the process works in the form of layers.
It slowly dissolves into the centre until eventually you have a tiny ‘stiletto heel’ of salt right at the bottom centre of the block holding the block up. Eventually this physically collapses and the salt drops, and the process starts all over again.
Typically, it is taking a 10 mm bite into the block at each regeneration.
Is a water softener a luxury item?
No. A water softener will pay for itself in just three to five years. It will provide the luxury of soft water for washing and showering and the benefit of removing scale from your home.
The savings you make on purchases of household cleaning products, reduction of energy used and the extended life of washing machines will provide the luxury for free.
How long does it take to remove the scale when you start using softened water?
Hard water comes into the house at approximately 300 ppm.
When it has passed through the water softener it is at virtually zero. As it enters the pipes its just like as if it was going back underground and is starts to dissolve the chalk and lime again as if creating a new cave.
It will therefore come out of your tap at approximately 10-15ppm of hardness.
This hardness goes down the drain and over a period of time all the existing scale in the house goes away in the same method.
The scale will be removed from in your kettle within six weeks. You can see this yourself happening typically its gone within a couple of weeks.
We guarantee that the scale will be gone from your heat exchanger within six months and from the rest of your pipe work within two years.
Customers that have never had a water softener before do not notice this. They think the water is brilliantly soft at 15ppm.
Customers that have had a water softener in a house and take it with them to a new house that has a scale build up in the pipe work notice that the water quality is not as good as before. This is because it is running at between 10-15ppm.
You also get this phenomena in homes with only one or two people living there. Over the weekend if they don¹t use the hot water it spends at lot of time in the hot water cylinder dissolving the scale and the hardness will go up over 20ppm which is noticeable.
If they use a lot of water, hardness only ever gets up around 5-10ppm.
How much should I reduce the amount of cleaning products I use now that I've had a water softener fitted?
As a rough guide, we recommend you reduce the quantity of most cleaning materials such as soaps, floor, kitchen and bathroom cleaner and washing up liquid by 50%. Washing powder, conditioner and dishwasher powder can normally be reduced by up to 75%. Dishwasher salt and scale removers should be reduced to zero.
Do razor blades last longer with softened water?
A razor blade will last longer with softened water.
Why? We are not absolutely certain but we did some experiments and found that in hard water they lasted two weeks and in softened water they lasted seven weeks.
Photographs through an electron microscope showed the blades receiving far more damage in the hard water than in the softened.
We believe that the hardness minerals in the hard water, corrode the coating on razor blades.
Can I use softened water in my swimming pool?
The recommendations of the Pool Water Treatment Advisory Group in the UK are to maintain Calcium hardness between 75 and 150 ppm as CaCO3.
If you soften below 75ppm it will tend to slowly dissolve the (Calcium from the) grout on a tiled pool and also etch any Calcium based coping stones. Fully softening also makes it harder to maintain the pH as the water then has a lower buffering capacity.
So partially softening typical “hard” water is OK but fully softening is not a good idea.
In a typical hard water area of 300 ppm area most people do not bother to soften.
A block salt water softener can be used to soften the water but it would have to be done over a period of days as the softener needs to stop and make brine from the salt blocks which takes over one hour. Half fill the swimming pool and then soften the remainder to give you half and half and keep the level of hardness below about 150 ppm.
For a typical unit in an area of approximately 400 ppm run the softener at about 20 litres a minute for a period of 30 minutes and then stop for at least an hour. Start again and repeat as required.
Is softened water ok for pets to drink?
Yes, the softened water meets the EU Directive on water quality for human consumption and also for pets with the possible exception of some exotic tropical or ornamental fish for which the aquarium may need special attention. Advice should always be sought from an aqua culturist if in doubt.
What does softened water taste like?
This is a matter of preference. Often people tend to favour the type of water they grew up with for drinking. Some would say that softened water is bland.
Most people prefer the taste of softened water in tea and coffee. The difference in taste compared to hard water can be quite significant.
Ultimately, the taste of your water will highly depend on your incoming water supply. You will only really be able to find out what your water would taste like after softening by having some of it softened.
Is there a legal requirement for a separate tap to provide un-softened water for drinking?
No, but provision of a separate tap to provide un-softened water is recommended.
Does a water softener remove fluoride?
No. A water softener will only exchange positively charged ions (metals), calcium, potassium, sodium and magnesium but not negatively charged ones like fluoride, chloride, sulphate or nitrate.
