Note: Chlorine type tastes and smells are normally associated with chlorine added to the water or chlorine reacting with rubbers and plastics found in the home. They aren?t harmful but there?s lots you can do to prevent them. Let?s see if we can find out what the cause is...

Diagnosis

It sounds like you have noticed the chlorine we use to disinfect the water supply to make sure it is safe to drink. This is a very important part of our water treatment; we monitor this process very carefully, 24 hours a day to make sure that the right amount has been added. A quick and easy way to remove the chlorine is to leave the water in a jug or open topped container in the fridge for a few hours to let the chlorine escape.

Note: If you notice the taste in boiled drinks only then it is probably a small bit of rubber or plastic in your kettle reacting with the chlorine we use to disinfect the water supply to make sure it is safe to drink.

Chlorine is a very important part of our water treatment; we monitor this process very carefully, 24 hours a day to make sure that the right amount has been added. Sometimes the chlorine can react with plastic or rubber parts in plumbing or appliances and cause a TCP, medicinal or metallic type taste or smell.

It isn't harmful but we know it doesn't taste very nice in your favourite cup of tea! You can easily find out if it is your kettle causing the problem by boiling the water in a saucepan instead.

Note: Ok, it might be that the reaction is occurring earlier on in your pipework so a little more detective work is needed?

Note: These types of tastes and odours are normally caused by a small bit of rubber or plastic somewhere in your plumbing reacting with the chlorine we use to disinfect the water supply to make sure it is safe to drink. Chlorine is a very important part of our water treatment; we monitor this process very carefully, 24 hours a day to make sure that the right amount has been added.

Sometimes the chlorine can react with plastic or rubber parts in plumbing or appliances and cause a TCP, medicinal or metallic type taste or smell. It isn?t harmful but we know it doesn't taste very nice in your favourite cup of tea! The problem is likely to be one of three things:

- Kettle? problem will only be noticeable in the boiled drinks.

- Flexible hose to appliance such as washing machine, dishwasher or other appliance plumbed in (such as a fridge with an ice maker)

- Other plumbing fitting such as rubber tap washer or flexible tap connector If you still have trouble fixing the problem, speak to an Approved Plumber to ask their advice or give us a call and we will do our best to help.

Note: You can easily find out if it is your kettle causing the problem by boiling the water in a saucepan instead. Boil fresh water from the kitchen cold water tap.

Diagnosis

It sounds like the problem is caused by your kettle. If you have only just bought it then over the next few weeks you might find the problem goes away on it's own.

If it doesn't, you could try the following:

- Rinse the kettle each time and only boil fresh water

- Stand the water in a jug in the fridge for a few hours to remove the chlorine before boiling it in the kettle.

Diagnosis

Flexible hose
Unapproved flexible hoses are easily available and you may have one connecting one of your appliances. If you do, this could be the source of the problem since water can sit in them for prolonged periods of time and start to taste and smell almost immediately.

Why? We already know chlorine can react with rubber or plastic to produce this taste and smell, well sometimes water inside this hose can be pulled out and can be noticeable at your kitchen tap and in drinks.

WHAT CAN I DO ABOUT IT?
Luckily, it's an easy fix. If you're feeling handy, check to see if you have a check valve (sometimes known as a non return valve) at the top of the hose where it connects to the water supply. This might be silver or brass in colour and will normally have an arrow on to show the direct of the water flow (into the appliance). These valves will stop any water backflowing out of the pipe.
If you don't have a check valve fitted, you can still work out if your appliance is causing the problem.


1.Find where the water supply goes into the appliance.
2. Locate the isolation valve (there is normally an isolation valve at the top of the hose).
3. Turn the water off to the isolation valve and leave for a few hours or overnight if possible.
4. Continue to use your water as normal. If you don?t notice a taste or odour to the water after you have isolated the appliance then this is likely to be the source.

Diagnosis

Other plumbing fittings:

- Try checking other mains fed taps in the property to see if you can narrow the source down to one tap. If not, you can try changing the washer in the stop tap.

- Have you done any plumbing work or had any new appliance or taps fitted recently?

- Rubber tap washers can sometimes cause the problem and so you my need to change one or some of these to non phenolic ones.

- Check under your sink to see if there is a flexible tap connector fitted. These are normally rubber hosed covered by silver mesh and are an easier way to connect the pipework up to the taps. If the taste or smell is isolated to just this tap, try changing this connector for a WRAS approved one.

Is the problem more noticeable first thing in the morning or after the water has been left standing for a period of time? Often giving the tap a good flush through will clear any water which has been sitting in the pipes and should improve the taste.

Diagnosis

Check your water tank, it may be that it needs cleaning. Make sure the water is able to turn over properly (the inlet should normally be at the top and the outlet at the bottom in the opposite side).

Make sure that the tank has a well fitting lid.

Diagnosis

If the problem seems to improve when you run off any water which has been sitting in the pipes then this suggests it might be something to do with the plumbing. If the water also appears warm, try lagging the hot and cold pipes to prevent this.

If you still have trouble fixing the problem, speak to an Approved Plumber to ask their advice.
