Common causes to bathroom sinks and shower waste traps is a general build up of hair and soap scum that tends to bind and can settle in the waste traps. Other common causes for blocked toilets are fat, oil and grease, rodents and household pets such as pet fish and pet animals and foreign objects like toys and toilet bowl fresheners. I have come across kitchen sinks, blocked from some sink unblocking detergents as some detergents can crystallise when poured down the sink and can cause a hard build up of residue when mixed with hot or cold water. Others are coffee grounds, tea bags, oil, grease, fat and food waste including starches.

Bathroom waste and traps get blocked by hair. Kitchens waste and traps get blocked by grease and any number of things from waste food to cutlery. Drains get blocked by wet wipes and sewers get blocked by roots, rodents and raw sewage. Toilets get blocked by over use of wet wipes and loo roll. Sani Macerators get blocked by condoms, surgical gloves and tampax.

I would definitely agree on cooking oils and fats as a big problem, also another issue is wet Wipes. Again just to add, another problem I've seen many times is poor drainage installation.

Congealed cooking oils , fats and grease are our most common adversary usually within the external kitchen waste gully drain but thankfully such a build up is no match for our high pressure water jetting equipment and can be efficiently removed with relative ease. The scourge of most drainage contractors and water authorities is the increasing disposal of wet wipes within drainage systems and although most of the packaging describes the products as flushable based upon our daily experience of dealing with them we would recommend that they are only disposed of in a bin, unlike tissues they are insoluble and do not break up within the drainage system and over time will build up until you have a plug of them completely blocking a drain run which can prove to be a lengthy process to remove them. Other causes of blocked drains that are not related to specific usage could be an underlying problem within a pipeline for example tree roots growing through an open joint and restricting the diameter or a displaced joint causing tissues to snagg and encrustations to build up. A professional drainage company when undertaking a blocked drain clearance will provide a reliable diagnosis backed up with a quick look see drain camera inspection as to what caused the blockage and advise on the best course of action if there is any concern of a recurrence.

This would be wipes even though a number of things that cause blockages from nappies, sanitary towels and kitchen roll but also found the plastic things they put on the rim of the WC drop off and fall into the pan, these do cause issues. If does come from the kitchen area then this would be grease and if the have a waste disposal then lack of water running through this when rice and pasta are put down there.

In my experience blockages are most commonly blocked by wet wipes. Blockages on kitchen sinks are usually caused by fat/grease and basins, showers and baths by hair. Therefore the easiest way to prevent blockages, would be to not flush wet wipes or even the “flushable” ones and don’t pour cooking fat down the sink.

Food and grease are the most common causes of blockages on kitchen sinks and can normally be cleared with a good plunger or sometimes may require removing trap and cleaning. For toilet wastes the most common causes are wet wipes which should be binned rather than flushed away, if the blockage cant be removed with a plunger then it may need to be jetted from main drain, and for showers/baths its normally hair that caused blockages and generally be removed with a plunger, you can try to catch hair by placing a strainer over plug hole.

The most common causes are left over food for the kitchen and for bathrooms it is hair. Luckily hair blocking the plug can easily be tackled by off the shelf drain cleaners and even bleach. Food/grease can be a little more difficult as you will need to take a part some of the waste pipe work but it can all be done by hand without the need for specialised tools. Ofcourse the best method to stop block drains is prevention. Don't flush things that shouldn't be flushed, scrape your plates and dispose of oil correctly.

Two most common faults for a blocked drain is food waste/fat/grease in the kitchen sink and hair in the bathroom waste, either bath, shower or basin can easily get blocked, and drain cleaner doesn’t have an impact. Try removing the waste trap from under the sink/bath, shower or basin and see if that’s all that is blocked first, otherwise a professional will be required

The cause of a blocked drain could be one of many different factors. Food waste down a kitchen sink, hair build up in a bath or a shower, or anything but toilet roll down a toilet! All this added together will effectively reduce the flow of the waste water and make excess waste build up quicker and quicker which will cause the pipes to block.

Blocked drains are mainly caused by people putting items such as tampons, baby wipes, nappies and kitchen roll down toilets. By people putting large bits of food and fat down kitchen sinks. Simply put blockages would be avoided if people didn’t do these things. The reason why we should only put toilet paper down a toilet is because it disintegrates. Nothing else does, it clogs all together causing a nasty blockage. Ventilation is a factor, especially on internal stacks. Durgos are prone to going wrong and this could lead to a blockage.

Although blockages in drains are mainly caused by items that are put into the drains , it is also important to know that correct ventilation of a drainage system can have an effect on blockages. Venting to atmosphere is always the best option but some systems may be using an automatic air vent fitting which can fail if not installed/maintained correctly and also have a tendency to freeze in loft spaces when not insulated.

A blocked sink is usually down to food stuff being washed down the sink like oil, fat, rice etc. Toilet blockages are usually down to too much toilet paper being flushed in one go, wet wipes being flushed, sanitary ware, cotton buds etc but van also be down to how the soil pipes were cut, if the edges were not cleaned and smoothed down they can cause debris to snag onto them. Baths and showers are usually hair but these can be removed quite easily by hand.

It really depends on a numerous amount of where the issue is. Some of the issues can be kitchen sinks- usually grease or food. Showers- usually hair or a build up of dirt. Toilets, usually wipes or a build up of dirt on older toilets. Baths will be hair or a build up of dirt. all these issues can be resolved by the drains falling downhill from the appliance to the main drain. The main drains can suffer from several issues including roots breaking through the drain, badly installed drains, drains which join neighbours drains which can provide too much dirt to be removed in one go, old drains which are smaller then the standard used these days and just a build up of wet wipes. the best advice I can give is to get the issue looked at with a drain camera before unlocking so the issue can be assessed and repaired before it becomes a recurring issue.

Blocked drains are invariably caused by items other than water. Blockages as the word suggests occur when something blocks or restricts the flow of water through the drain pipe. There is normally a gradual reduction in the flow of water from the sink, hand was basin or toilet. Incorrectly plumbed in dishwasher can cause a build up of food and grease debris to form in the pipe reducing the flow through the pipe. Inappropriate items being put or falling accidentally into the drain also cause problems. The best way to avoid blockages is to routinely clean the pipe by allowing clean hot water to run through the drain. This can be water previously used for cleaning the basin, shower etc. I recommend filling the sink or hand wash basin with hot water add an additional drop of washing up liquid and release the contents of the sink down the drain, the weight of the water combined with the flow and the detergent gives the drain a clean and helps to remove any initial build up of fats and debris.

The most common blockages on domestic drains seems to come from wet wipes, or toilet wipes, which dont dissolve and bundle together within the drain and cause a blockage. Also a big factor is fat. This can cause so many problems, and it clogs drains the same way as arteries. As deposits get stuck on the side of the pipe, as other materials and fat are put down the drain, the deposits that are stuck in the pipe grab bits as they pass by and build up until it blocks the pipe and doesn't allow any solid to pass through.

The most common problems with blocked drains are usually down to the user and more than likely things going down the toilet. Keep your eye on air fresheners than sit round the rim as these can cause blockages. Wipes are possibly the biggest problem, especially the ones that are now branded as “flushable” wipes. Other problems are food and fat down sink wastes and hair in showers and basins. Sometimes it can be caused by the drainage pipe having been cracked and collapsed, usually caused by external work or movement in the ground.

The most common and preventable causes of blocked drains, is user based. Sometimes WCs & sinks are seen as a way of disposing oils, fats, paints, plaster, wipes (even ones that state flushable!), which may run away from the property, but will stop in the drain. This blockage, will eventually catch other matter, which causes it to grow to the point it becomes blocked. We are frequently called to remove these preventable blockages at properties. There is other reasons to why a drain may block, such as, tree & bush roots, displaced joints, ground movement.

Blocked drains can range between incorrect installation fall and or size of the drain itself. When installing new drains to old consideration should be made to how the connection is made. A new access chamber would be advised or a connection the is swept and going with the flow. Another issue can be found by the wrong items being flushed either to large or to solid for the intended use of the drains. Kitchens who discharge a lot of waste into the drains are advised to use fat strippers or fat separators.
