One important factor to consider is that school buildings are generally much larger than personal homes or apartments. That means that HVAC systems in school buildings are going to have to be larger as well. With more area to cover in terms of ductwork and a more powerful unit needed to heat, cool, and ventilate a school, there is also a greater chance of something going wrong.

Also, when a problem does occur it may be harder to track down its exact source since the system is so large. That’s why it’s a good idea to do regular preventative maintenance on an HVAC system so that problems can be detected and fixed early.

It’s a major problem if any element of an HVAC system fails while school is in session. If the heating fails during the winter, then the students will get cold and could even get sick if they’re stuck in the cold for too long. The school will no doubt get some complaints from parents if their children come home sniffling because the heating system broke.

It’s equally important that the cooling and ventilation systems work properly. Most school classrooms have anywhere between 20 and 40 people packed in to a relatively small space. If the cooling system fails on a hot summer day, those classrooms can practically turn into saunas. The body heat of so many people all in the space can really ramp up the temperature.

Ventilation problems can also be made more severe by the sheer number of people who are often in classrooms. It could lead to students getting really uncomfortable, and potentially even cause problems for people with asthma or similar conditions.

In order to keep on top of HVAC system maintenance in a school building, there are a few important steps that should be undertaken. The filters in the units should be replaced once every couple of months in order to ensure that they stay clean and don’t become a breeding ground for mold and fungus. The filters will need to be changed more often in dirtier environments.

Also, the evaporator and condenser coils should be cleaned once or twice each year. Evaporator coils are pretty much always damp, making them a likely spot for mold or fungus to grow and affect the air supply. Condenser coils are easily damaged and degraded by dirt buildup. Routine cleaning of these key components of the HVAC system will not only extend the life of the system, but will also make it run more efficiently.

These key steps, along with routine inspections, will help make sure that a school’s HVAC system stays in good shape.

Sometimes a slab leak will be obvious. It could be a noticeable (or dramatic) increase in your water bill. You may be able to spot moist, wet, or damp spots (or stains) on your floor or carpeting. Maybe you’ve noticed low water flow. There may be water coming through your foundation or your foundation may begin to settle.

Slab leaks can occur in your homes potable water line or in your outgoing sanitary sewer line, both of which may be embedded in or under the foundation of the building. Leaks in either set of lines can cause large amounts of damage to the foundation and each has its own list of causes, some are shared. Slab leaks in the potable water line can potentially be more destructive because the supply water is under pressure. It runs through or under the concrete slab, then to the water heater where copper pipes split off and carry water to all the hot and cold water fixtures in your house.

Five Main Causes of Slab Leaks

The first is electrolysis, from the copper pipe coming into contact with soil. The second is due to the foundation shifting (because of poor design or installation, or a change in the moisture of the ground) your pipes pull apart. The third is pressure that is too high (the size of the pipes installed may be too small) which will corrode copper pipe. Leaks will also form at points where the pipes bend or change direction. The fourth cause may just be poor workmanship or craftsmanship, inferior plumbing supplies or materials (e.g. soldering, pipes) or a plumber that rushes or is inexperienced. It could also be a kinked line (a piece of pipe with an imperfection) or nicked by another (non-plumbing) worker, such as the concrete contractor. Chemistry is the fifth, either the chemical interaction between copper water pipes or the water running though them (copper pipe is very susceptible to pinhole leaks caused by the chemical composition of your water).

Slab Leaks In Sewer Pipes

Incoming water lines will constantly leak since they are under continuous flow and pressure – but slab leaks in sanitary sewer pipes only leak when a toilet is flushed, when someone takes a shower or bath, or when a faucet/tap is turned on. There are four main causes of slab leaks in sewer lines. The first is a fracture or break in the cast iron, galvanized steel, or PVC sewer pipes, caused by shifting of the foundation. The second is, in the case of cast iron or galvanized steel pipes, parts of the pipe may be exposed to soil, sand, or gravel which are porous to water -this can lead to corrosion. The third cause is the chemicals, solvents, and cleaning solutions that are poured down the drain which interact and corrode the metal pipes. The fourth cause is poor workmanship or craftsmanship, inferior plumbing supplies or materials, or a second-fiddle plumber.

If you have a slab leak, or think that you do, you should consider getting a free estimate from a qualified epoxy pipe lining company. Don’t automatically go through the time-consuming (days or even weeks) and expensive process of either re-routing the affected plumbing altogether, or digging/breaking up your concrete floor or foundation, destroying the flooring you may have covered it with, and buying new replacement pipes. You may be able to save time and money by restoring the pipes you have, right where they are (by connecting epoxy lining equipment to your existing fixtures and valves). A conventional repair (digging up and replacing pipe) will solve your problem right now, but epoxy pipe lining can protect your plumbing system from future slab leaks.

In the United Kingdom, housing prices dropped by fifteen percent over the last twelve months. If a house is sold today it is likely that the house is sold at a loss. For a long time, the real estate market operated with the buyers understanding that they would be able to sell their homes for a profit later on. The only way for this rule to still apply to the selling price of a person’s home is if the homeowner drastically improves the value of the house that he or she is trying to sell. Upgrading the plumbing and heating systems in a house is one of the best ways to raise the value of a house.

Home owners are applying more value to environmentally friendly house upgrades. Updating a house’s heating and plumbing systems can be done by installing solar panels as well as a water heater that is energy efficient. The installation of solar panels can cut down a house’s CO2 output by roughly half a tonne every year.

This upgrade increases the value of the home while reducing the house’s impact upon the environment. The energy efficient water heater is an upgrade that will impress any home buyer. These water heaters are able to heat water very quickly and cheaply and able to keep the water heated for long periods of time.

Underfloor heating is another house upgrade that will drastically increase a house’s value. Underfloor heating is provided by wet and dry piping systems. These systems transfer heat from heated water or natural gas through the floors of a home and raise the temperature of the rooms above. Residents can enjoy a uniform and reliable temperature without having to deal with the upkeep of a wall heater or radiator.

Underfloor heating is more affordable than traditional heating systems because it is more efficient. Recently underfloor heating’s market share has risen, which means that installing underfloor heating can improve the value of a house by quite a lot

Other upgrades a house owner should consider include upgrading the kitchen and bathrooms of a house. There are a great many ways that these rooms can be upgraded that will considerably raise the value of one’s house. Using modern fixtures and ensuring that the flooring is new will certainly raise the value of a home considerably. Installing new cabinets and light fixtures is another upgrade that home buyers will appreciate.

An unpredictable housing market means that increasing the value of one’s home relies almost entirely upon the home owner. Upgrading the heating and cooling systems of a house and taking steps to ensure that the plumbing is modern and efficient are two of the best ways that a home owner can make sure that he or she is able to increase the value of his or her home. Underfloor heating, upgraded kitchens and bathrooms and “green” additions are some of the steps a home owner can take to raise the value of a house.

The majority of UK homeowners aim to run an energy efficient home. After all, it can save you time, money and improve the environment. The government has started to focus on energy efficiency as well. Building Regulations now include set standards that all hot water and heating systems must meet. A hurting economy and ever-increasing prices adds further pressure. Now, more homeowners than ever are having trouble paying the bills.

The dramatic change in climate has increased the importance of attaining energy efficiency. As the number of natural disasters related to climate change increase, the number of concerned citizens also rises. Homeowners are often unsure what they can do. There are several easy changes to the home that can greatly improve its overall efficiency. Ensuring your home has high-efficiency heating and hot water systems is a good way to start. There are several options available to the concerned consumer.

High efficiency condensing technology can prove extremely worthwhile. When faced with the decision to replace or repair their boiler, consumers are often unsure of what to do. They should be supplied all the facts so that they can make the choice that is best for their home. It is common for the homeowner to depend on the installer to provide guidance. Therefore, the installer plays quite a large part in this whole process.

Boilers are often expensive. When consumers consider this and the additional installation fees, they usually choose to just repair their current boiler instead of investing in a new high efficiency boiler. This can prove to be a costly mistake. Older boilers can be repaired but their level of efficiency can never be improved. A faulty boiler just creates problems and produces unnecessary expenses. The cost of repair and running of older boilers is usually higher that the price of total system replacement.

If costs don’t persuade you then, maybe the impact your choice has on the environment will. Homes in the United Kingdom are responsible for 21% of all carbon dioxide produced. Heating and hot water systems make up 80% of that number. Energy efficiency lowers bills in addition to helping the UK attain its goal of decreasing carbon emissions by 2010. Heating and hot water makes up well over half the cost of a typical fuel bill. High efficiency boilers can cut bills by up to 30% and save the typical home 200 a year.

There are several UK manufacturers that sell heating and hot water systems in a variety of makes and models. Common features include cast aluminium-silicon heat exchanger, brass waterset, energy efficient pump, and a concealed system connection that greatly improve system performance. A centrally located telescopic flue kit with preformed connections and pre-fitted mains electrical lead results in fast and cheap installation. Drop-down controls and a spacious interior allows the appliance to be serviced with ease. RF, radio frequency, controller versions are also available. They provide the user with complete touch of a button control. Warranty agreements vary company by company but usually provide 10-year parts warranty on the heat exchanger and two-year parts and labour coverage on the entire system.

Before you start, check the manual provided with your machine in case there are special instructions specific to the model you have bought. (Such as removing the transport bolts before use – these lock the internal workings in place to prevent damage in transit)

Attaching The Water Supply
You need to connect the water supply to your machine using the hoses supplied. There may be one for hot and one for cold, OR it’s quite likely your new machine only requires a cold hose (in which case it heats the water itself). It’s red for hot, blue for cold. Hoses may already be attached to your machine, but even if not they simply screw on at both ends. Make sure the threads are not crossed and you do them up tightly before continuing. Tightening by hand should be sufficient, using a wrench can break the connector!

Waste Water
This pipe is where the dirty water goes when your machine empies after each rinse/wash. A stand pipe and trap is the most common method. Your waste pipe simply sits loosely inside the upright stand pipe. There is no air tight connection – this is deliberate and prevents dirty water getting sucked back into your machine.

And there you go – installing plumbing for a washing machine is not nearly as hard as it seems!

You may have to call a plumber if the problem isn’t straightforward, but there some very simple reasons a toilet won’t flush, that you can check for and fix yourself.  Check these first, but call a plumber if you are not confident about replacing any parts that turn out to be broken.

Easy Things To Check Why Your Toilet Won’t Flush

1. Float valve/ball. Your toilet cistrern should be full of water with the large plastic float ball sat on tap of the water. If the ball has become snagged against the side of the cistern then it may not fill at all, or enough. Gently bending the rod may fix the problem. If the rod is broken or the ball ‘leaking’ and filling with water, they will need replacing.

2. Handle. Too loose? Too tight? Check the mounting nut, and chain connections. They may simply need clearing of limescale or adjusting.

There are many reasons a toilet won’t flush, but don’t be afraid to lift the cistern lid and look around. It could be a simple fix.

But basically the steps you need to follow are:-
1. Turn the water supply off (check under your sink for the tap)
2. Put plug in the plug hole – to avoid losing anything down the sink!
3. Remove cap of the tap
4. Unscrew/remove the handle to expose head gear nut
5. Remove head gear from the body
6. Replace the old washer on the jumper
7. Reverse your steps to put your tap back together again

Tools required: replacement washer, knife, screwdriver, adjustable spanner, pliers.

And there you go, no more leaky tap. Told you fixing a dripping tap was not complicated!
