I agree with Raptor (sound like DC in election debates).
If OP wants to take item back then the following may be of help (taken from well known consumer website and collated for ease of reading). I appologise in advance for the 'wall of text' but many of us buy items and sometimes they are not what we expected so may come in handy.
Top 10 myths about your consumer rights
Many an upset shopper has cried “I know my rights,” but do they really? There are so many rules and regulations, covering just about every aspect of buying and selling, together with guarantees and promises from shops, that it can be tricky to know exactly what you are entitled to.
There is also plenty of misinformation; look at almost any online forum and someone will tell you what you are entitled to do but they may not necessarily be right.
So, before you take up cudgels against a supplier, it’s important to know what your rights really are, and how best to enforce them. Over the next few pages, we will look at some common beliefs about consumer rights and see whether they are true.
1. You have to return unwanted goods bought online within seven days
Wrong. Goods bought online within the EU are covered by the
Distance Selling Regulations. As a general rule of thumb, you have an unconditional right to cancel your order (unless it is for perishable goods or customised goods) before the end of the cancellation period. That period ends seven working days after the day on which you received the goods.
The Regulations say you must also receive details of the warranty, the address for any complaints and information about your right to cancel and how to exercise it. This must be supplied in a ‘durable medium’, which means on paper or via email or fax so it can be in a catalogue, but not simply on a web page.
If you do not receive the information before the goods arrive, your cancellation period ends seven days after you receive it, or three months and seven working days after you received the goods, whichever is sooner.
The date on which you give notice, by sending an email or posting a letter, will be the date on which you cancelled the contract. It does not have to reach the seller before the seven working days is up, but we recommend using recorded delivery or obtaining a certificate of posting.
You are entitled to get your money back within 30 days, even if the seller has not yet collected the goods, and the money refunded should include the cost of the delivery to you, though the seller can ask you to pay for the return of the goods, if that was specified in the information regarding the order.
2. ‘I can take goods back to the shop for a refund if I change my mind’
No, you cannot. You have no right to a refund if you change your mind. However, some shops may allow refunds or exchanges as part of their own ‘no-quibble’ promises. These may have their own conditions attached and it is largely up to the shop what they offer.
If you have bought by mail order or over the internet, though, the purchase will fall under the Distance Selling Regulations and you have a right to cancel the order, except for custom-made products, perishable items, newspapers or magazines, or for products such as DVDs, CDs or software that you have opened.
However, you must still take reasonable care of the items and you must notify the seller that you wish to cancel the contract within the time limits noted earlier.
3. ‘We will not repair/refund that unless you have the receipt’
Wrong. A receipt is the most common way to prove when you bought something and how much you paid, but it is not necessarily the only way.
What you need is proof that you purchased the item from the seller. For example, some shops may stamp or date a warranty card. A credit card bill or receipt may also provide suitable proof. However, if several things were bought at the same time the receipt may not be clear enough.
Some products, such as ‘own-brand’ items, are only available from specific suppliers and may only have been available at a specific time. However, relying on this may mean you have to accept an exchange or repair as it may not be possible for the shop to know exactly what price you paid for an item.
So, it’s a good idea to keep receipts, especially for expensive items, but it’s not necessarily the end of the world if they do get lost, as long as you have something that can show where and when you bought a product.
4. ‘You have to pay the carriage fee to return faulty goods to us’
Wrong. The Distance Selling Regulations are quite clear on this. The guidance for sellers from the Office of Fair Trading says “you should not charge return costs for goods that have been rejected because they are faulty.”
Contact the seller and ask them to arrange to collect the goods or provide a pre-paid envelope to post them back. Many sellers do this already, including a return label with goods that they post.
The Sale of Goods Act also says that the consumer should not be left out of pocket as a result of buying faulty goods. So, if you buy an item from a shop and discover it is faulty when you get it home, the shop should cover the costs of your return trip to swap it for a replacement.
However, it can sometimes be difficult to prove the exact cost of such a trip, so do remember to keep receipts for things like petrol, or consider using a courier or taxi, so that you know exactly how much the return cost. If you are using Royal Mail, send by recorded delivery and add the additional fee for this to the costs.
5. ‘You have to pay a restocking fee to return that item’
A ridiculous and illegal claim. The Distance Selling Regulations say that a seller is not allowed to make further charges when an item is returned, and specifically mentions administration and restocking fees.
They can only charge you the carriage for the return if they specifically stated you would have to pay that, in the information they supplied when the order was placed. This is often found in the company’s terms and conditions, so check before buying.
If, however, you return an item to a shop where you bought it in person, and it is simply unwanted, rather than being faulty, then the shop is not required to give you a refund, and could charge a restocking fee.
6. ‘I can demand a full refund at any time’
No, you cannot. If you were mis-sold an item – for example, you made it clear that you needed a product to do a specific task and the one sold to you could not do it – then you can ask for a refund. But do it right away.
Once you have started using a product, even if you only later discover it will not do everything what you asked for, it becomes second-hand. If it is no longer ‘as new’ then it is unlikely you will receive the full amount, unless the shop has a generous refund policy or you can prove that you were mis-sold the item.
That could be via a description in a catalogue or on the box (‘Mac compatible’ when it is not, perhaps), or by specifically asking for the seller to state in writing that a product will do what you want it to.
If you cannot prove you were mis-sold an item and the shop disputes your claim, a court may decide you have had a certain amount of value from something by using it, and the longer you use it, the higher that value will be. So if you return something after several months, it is unlikely you will receive the amount you paid for it.
7. ‘It’s company policy not to issue refunds’
Nonsense. Company policy cannot override the law. If an item you have bought is broken, does not work or do the job it is supposed to, then the contract of sale is broken and you can reject the goods and ask for a refund. You do not have to accept an exchange.
The law assumes that, if something breaks or goes wrong in the first six months, then it was faulty from the start, and it is up to the seller to show otherwise. After six months, you need to prove a fault was there from the start to get a refund rather than a repair.
As a general rule, after a month you will have to accept a replacement or repair, rather than a refund for faulty goods, but you should not be expected to accept repeated repairs or exchanges.
Again, if you simply return something to a store because you do not want it then the shop does not have to provide any kind of refund by law, although some may offer you a voucher instead of the goods.
8. ‘You have to return a broken item to the manufacturer, not the shop’
Oh no you don’t. When you buy something in the UK, your contract is with the person who sells it to you, not with the person who made it.
It is the seller’s responsibility to replace broken or faulty goods, not the manufacturer’s. It is sometimes quicker to deal direct with the manufacturer because many have dedicated repair departments but you must make the initial complaint to the organisation that took your money.
That is important because if you want a refund (for example, if multiple repairs are required and you decide to opt for a refund) the manufacturer has no duty to provide this. That is down to the retailer.
If you cannot contact the seller, perhaps because it has gone out of business, the item could cost more than £100 and you paid for it by credit card then the credit card company is also responsible, and you can contact them for assistance. You can also ask them to intervene if the seller refuses to deal with you.
9. Your warranty has expired so you have to pay for a repair
Not necessarily, but this one is a legal minefield. A warranty does not, and cannot, affect your legal rights. The law says that customers can demand damages (which a court would usually equate to the cost of repair or replacement) for up to six years after purchase in England and Wales, or five years after discovery of a fault in Scotland.
However, not all goods are expected to last for that long, and you would not be able to claim after three years for a repair to a product that, typically, would only be expected to last a much shorter time.
The way in which the item has been used could also be quoted in a court case, so for example a car that has driven more than 100,000 miles might be expected to last less time than one used for driving to the shops once a week.
This is where it gets difficult for items such as PC's. It is not possible to get a ‘mileage’ for a PC and any software added to it, along with upgrades such as extra memory or other hardware, makes it incredibly difficult to prove an inherent fault after several years. You would almost certainly have to do so in the
Small Claims Court.
If a repair is not possible, or economical, the level of any refund will be based on the use you had from the item.
10. ‘You cannot return a broken mobile phone after 28 days’
Wrong. However, mobile phones are more complicated than many other purchases because when buying a phone, you are often buying two things – the phone itself and a service from the mobile phone network.
If you buy a phone ‘SIM free’ or on ‘Pay As You Go’, so without a contract, then the phone has the same legal status as any other goods. If it becomes faulty you can take it back to the shop for a repair, replacement or refund. If it was bought via the internet or mail order, the Distance Selling Regulations also apply.
Many mobile phones are sold with a contract, where you must pay a certain amount per month for a set time for a phone together with an allowance of calls, texts and so on. The cost of the phone may even appear to be free.
If there is a contract for service involved, things are a little more complicated. The phone itself is still covered by the usual rules, so if it breaks (not because of damage caused by misuse or accident) within the first six months, for example, the seller would have to prove that it was not faulty from the start and should offer a repair or replacement.
However, even though you can return the phone itself, you also have a contract for the service. So, if the terms of that contract are fair, you could end up with no phone, but still have a contract for the mobile phone service. And you cannot cancel this just because the phone is faulty.
Since the cost of the phone is included in the monthly payments, if you reject the phone the provider should provide you with a replacement. If they cannot do this, and you took out the contract to get a specific phone, you may be able to argue that the contract should be terminated, but you will probably have to do so in court.
The difference between warranties and guarantees
Many people think their entitlement to repairs is governed by the warranty, or guarantee in the box of the product they buy. But as you can see from our myth-busting, this is not the case.
Just about every warranty or guarantee you read will explain that they do not affect your statutory rights: no company can take away rights that you already have in law. Of course, most offer fewer rights, and they would rather you did not know, for example, about your six-year time limit for claiming damages.
A warranty or guarantee is a form of insurance, often promoted as an incentive to buy. Once a company has made a promise in such a guarantee, it is legally obliged to stick to it but the terms of the guarantee do not prevent use of rights provided by the Sale of Goods Act and other consumer protection laws.
Extended warranties are a form of insurance against various types of wear and sometimes damage. Be wary of these, especially if a sales assistant is pressuring you.
In 2002 the Office of Fair Trading called the extended warranty market exploitative and referred its investigation to the Competition Commission, which described retailers’ offerings as “unfair and uncompetitive”. For more information read the
Before you buy section on the Consumer Direct website.
If you are still reading I hope it's helped.
From the above I think the OP might have a case for return under the mis-selling aspect, unless the pump actually only produces the db stated on the box or by the sales assistant and the OP did not check how loud that many db actually was.
It's most likely the vibrations, try putting some sponge or tissue E.T.C under it
