Lower water pressures won’t have the force needed to make an impact sprinkler system effective. If your sprinklers are falling short or don’t seem to be putting out water at a very high rate, you may be better off with a different method of irrigation.  You can find out how many psi’s you’re working with by calling your local water provider or using a pressure gauge that fits over the end of a standard garden hose. Most residential areas have an average water pressure somewhere between 40-60 psi. However, yours might be lower if you get your water from a pump or well. Impact sprinkler heads are usually sold in a couple different materials—plastic and metal. Plastic heads are lightweight, making them easier to turn with a conservative water flow of around 20-40 psi. While they tend to be slightly more expensive, metal heads will be better able to handle the strain of higher pressures.  Metal sprinkler heads are also more durable, meaning they’ll last longer and experience fewer issues.  If you’re unsure which type of head will work best for your home, consult with a home improvement or gardening expert while you’re shopping for an impact sprinkler system. A new sprinkler that has stopped performing to its usual standard may just be in need of a good cleaning. Remove the sprinkler head from the base and disassemble it to gain access to the nozzle and swivel bearing. Gently scrub each piece with hot water and a bottle brush to remove any debris or mineral buildup that may be inhibiting the sprinkler’s movement.  Common symptoms of a dirty sprinkler include a weak stream with normal water pressure, turning to one side and stopping, and failing to rotate at all. A mixture of vinegar and warm water can cut through heavy mineral and sediment deposits that have accumulated inside the sprinkler head.

One-sentence summary -- Make sure you're using a water source with a pressure of at least 15 psi. Choose the right sprinkler head. Clean your sprinkler periodically.

Q: Separators are usually not in for long. You will usually have your separators removed at your next orthodontist appointment, when your braces will be put in place. Up until this time, you should brush your teeth back and forth after eating. Brushing your teeth up and down can easily dislodge separators. Separators should not come undone during routine brushing. However, flossing can very easily dislodge a separator. After you eat, avoid flossing in the gaps between your teeth filled by a separator. You may feel some soreness after eating when using separators. You can manage pain with over-the-counter painkillers like ibuprofen, acetaminophen, and naproxen. Take the recommended dose on the bottle. This should take care of some of the pain. Separators sometimes fall out. This can be normal. Remember, separators serve to create space in your teeth for braces. If a separator falls out on its own close to your braces appointment, this means the space has been made. However, if a separator falls out 4 days or more before your appointment, call your orthodontist's office. Losing a separator this soon means you likely accidentally dislodged it via flossing, brushing, or eating. You may need your orthodontist to add a new separator.
A: Brush your teeth back and forth. Take precautions with flossing. Use over-the-counter painkillers to manage soreness. Talk to your orthodontist if a separator falls out.

Article: The width of the trenches does not matter, so you can make them as wide as your shovel or trowel. Some online sources will recommend shallower trenches, but 12 inches (30 cm) is safer. This way, you won't risk something digging into the soil and cutting the cables.  If you are digging in a grassy area, cover 1 side of your desired trench with a plastic tarp, then place the excavated dirt onto this. It will make clean-up easier. If you need to cross a pathway, continue digging your trench on the other side of it. Use a sledgehammer to drive a 1/2-inch (1.3-cm) diameter rigid metal conduit right under the sidewalk so that it reaches the other trench. Extend the conduit into the trenches, then use wooden blocks to prop it up. Make sure that the conduit has thick, rigid walls. Thin-walled conduits will corrode too fast and PVC ones are too weak. If you plan on installing a light post, dig a 2 ft (61 cm) hole into the ground, then insert the post. If you are using a small light on a stake, you don't need to do any digging; you can typically just drive the stakes into the ground. If you added a conduit, then feed the cable through it until it comes out the other side, then continue laying it down in the trench. Stack some wooden blocks under the conduit to prop it up.
Question: What is a summary of what this article is about?
Dig 12 in (30 cm) deep trenches where you want the cable to go. Drive a metal conduit to connect 2 trenches, if needed. Dig a hole for a light post, then add the post, if needed. Set the cable into the trench.
