Clog Removal Some plumbing problems require the tools and know-how of a plumbing expert. Others simply require a determined homeowner and some basic equipment. Some of the most common of these plumbing issues are clogs. The first way to clear a clogged drainpipe is to try using a plunger. Place the rubber cup over the sink or toilet drain to create a watertight seal. Then firmly push the plunger up and down. This will force water through the system and hopefully send the blockage on its way. If the clog cannot be removed with a plunger, an auger may be needed. A closet auger has a relatively short flexible cable and a corkscrew tip. This will be sufficient for pulling out clogs in the first few feet of a drain system. If the clog is further back, you might need a cable auger. Also called a plumber’s snake, this tool has a long flexible cable that can extend far back into drain system. It will also have a cranking mechanism to extend and retract the cable. Note: To avoid damaging pipes, an electric power auger is not is not recommended on lighter plumbing systems.
a) What is a plunger? b) What are the tools for clearing clogged drains? c) What grammatical phenomena can you analyze in the text? d) Find in the text the sentences in the Future Simple. Read them and analyze the verbs.
A to advertise clog removal tools B to describe common causes of clogged drains C to warn of the damage clogs can cause D to explain how to clear a clogged drain

Pipe Repair Pipes make up the backbone of your home’s plumbing structure. Without proper maintenance of pipes, your entire plumbing system could collapse. The key to maintaining healthy pipes is catching problems early. A pinhole may seem minor, but it could quickly lead to a massive leak. These holes must be patched right away. Pinch a pipe repair clamp around the hole, and check surrounding parts for other signs of corrosion. Always ensure the area is clean and dry before applying a clamp. For large holes or split pipes, you may need to cut the affected area and slice a new piece into the gap. Make sure you smooth any burrs around pipe edges with sandpaper after cutting. Then secure the replacement piece with ferrules. Take care to leave adequate overlap between the new piece and existing pipe. Some types of pipe, such as braided-stainless-steel hoses, can be difficult to patch. Fortunately, these connections are often short, so the whole pipe is easily replaced. And remember, always turn off the water supply before performing any pipe repairs. Otherwise, your small leak could turn into a massive flood.
a) What are some different types of leaks that form in pipes? b) Which repair methods are best for different types of leaks? c) What grammatical phenomena can you analyze in the text? d) Find in the text the sentences in Present Simple. Read them and analyze the verbs. e) Find the Genitive case. Give an example.

TO: Employees of Atchison Plumbing FROM: Stephen Atchison, Owner DATE: October 18 SUBJECT: Communication Issues Hank Milton is the owner of Milton Homes. Mr. Milton is one of our biggest clients. Yesterday I received an email from him. Some of the fixtures in the Paradise Subdivision were not installed correctly. Apparently, there was confusion about the instructions on the rough-in sheet. In these cases, employees should consult their on-site supervisor. This will allow you to confirm the correct way to do things. The employees on the job site were not carrying their smart phones. As a result, they were unable to call each other. The posted company policy states employees are to carry their phones while working. The company provides phones and two-way radios to all employees. These allow you to contact me and each other while on the job. From now on, please be sure to carry your phones and radios. Milton Homes received building permits for another subdivision. We will get the work orders for the plumbing. Let’s do it right this time.
a) Why is it important for employees to be able to communicate with each other on job sites? b) What are some methods they use to communicate on job sites? c) What grammatical phenomena can you analyze in the text? d) Find an example of the Possessive Case of a noun. Read it.
1 – The email contains a new rough-in-sheet. 2 – Some plumbing company employees violated company policy. 3 – The client no longer wants to use the plumbing company.
