Wear a pair of latex or nitrile gloves to keep your hands clean while handling the salt cell and PVC pipes. Also put on protective eye goggles to shield your eyes when cutting PVC pipe. Use the electronic controls attached to the pool's plumbing system. Press the "off" button to stop the pump. The salt cell is a cylinder, usually colored white, on a pipe near the control panel. It attaches to the pipe through a pair of plastic PVC rings called unions. Turn the unions counterclockwise by hand until you can pull them off the salt cell. Then, lift the cell off of the pipes. You will need to replace the salt cell with new pipe before you can activate the pump again. Measure the space between existing pipes where the salt cell used to be. Also note the diameter of the existing pipes by measuring across their openings. Get a new pipe that is the same diameter as the existing pipes. It will fit into any fittings already attached to the old pipes. You will also need 2 straight fittings to connect the new PVC pipe to the old ones. Dry-fit the pipe and the connectors where your salt cell used to be. If the pipe is too long, place it in a vise set on a flat workbench. Use a hacksaw to cut the pipe to size. Some stores may cut the pipe for you if you give them your measurements. Wipe down the pipe ends with a clean cloth. Use the brush included with the purple primer to paint about 3in (7.6cm) along the ends of each fitting. Coat the inner end of each fitting as well as the outer portions both the new and existing pipes. Then, wait about 10 seconds for the primer to dry. Take the cap off the PVC cement bottle to uncover the brush. Spread a thin, even layer of cement over the outer ends of the fittings. Also coat the inside portion of the pipes. Spread the cement about 3in (7.6cm) as well, covering all of the primer. Set a fitting in each existing pipe. Push the fittings as far as you can to ensure they glue in place. Situate them so the other opening points outwards towards the opposite pipe. Move the pipe to the open space in the plumbing system. Slide the new pipe into the fitting of the lower pipe. Give the pipe a quarter twist to the right to lock it in place. Then, pull the uppermost pipe back and slide the new pipe into its fitting. Avoid activating the pump again until the glue has settled. After about 2 hours, you can drain the pool and add chemicals to convert it to chlorine.

Summary: Wear gloves and goggles for safety. Turn off the pool pump. Unscrew the salt cell to remove it. Use a tape measure to determine what size PVC pipe you need. Cut a new PVC pipe to size. Brush primer onto the new and existing pipes. Spread PVC cement over the primed areas on the pipes. Place the fittings on the existing pipes. Set the new pipe in place. Wait 2 hours for the glue to dry.

Use a long-handled brush to scour the surface of the shingles and loosen stuck-on mold while it's dry and brittle. Focus your attention on the heaviest growth and hard-to-reach areas where the shingles overlapthe chemical treatment will take care of the rest. Make sure you're wearing your respirator during this phase to avoid breathing the mold particles that will be floating around. To get rid of mold and other types of growth for good, it's best to use a powerful chemical agent like chlorine bleach. You can whip up your own basic cleaner by combining one quart of bleach, one gallon of water, and cup (60ml) of trisodium phosphate (TSP). For maximum coverage, use a pump sprayer to disperse the solution. The chlorine will kill the mold-causing bacteria while the TSP will help remove stains and discoloration. Never combine bleach with any product containing ammonia. This can produce toxic chlorine gas which can be extremely hazardous to breathe. If you'd rather minimize your handling of chemicals, keep an eye out for preformulated treatments such as Wet & Forget or Moss Out at your local home improvement center. Start on lowest row of shingles and work your way backwards to the upper part of the roof. This will prevent the solution from draining in your direction. Continue spraying until you see runoff, then let the chemicals sit for 15-20 minutes to soak in and begin attacking the mold. Though it may seem like common sense, using a pressure washer is not advisable. The force they generate is enough to damage delicate shingles. The best time to clean your roof is during cool or cloudy conditions, when the solution won't evaporate before it's had a chance to be effective. Just make sure the forecast doesn't call for raina heavy downpour could wash away all your hard work. Empty the sprayer and fill it back up with fresh water, or snake the garden hose around to where you are. Sweep the stream over every part of the roof that you just sprayed to wash away the concentrated chemicals. Any remaining traces will dry naturally in a few hours. If not properly rinsed, chemicals like bleach and lye can cause permanent damage or discoloration.

Summary: Scrub away the thickest buildup. Mix up your cleaning solution. Spray the entire roof thoroughly. Rinse the shingles.

When the mussels are coated with the shallot mixture, add cup (118 ml) of dry white wine, the juice from 1 lemon, 1 cup (237 ml) of chicken broth, and a pinch of red pepper flakes to the pot. Stir well to ensure that the flavors are fully blended. You can use any steaming liquid that you like for the mussels. You could use all white wine or chicken broth or substitute beer if you prefer. Even plain water will work, though the mussels won't have as strong a flavor when they're finished steaming. Once you've added the liquids to the pot, cover it. Allow the mussels to steam over medium-high heat for about 5 minutes or until they begin to open. When the mussels have opened, mix in cup (15 g) of roughly chopped parsley and 2 tablespoons (28 g) of unsalted butter. Cover the pot again, and allow the mussels to steam for another minute so they soften. Once the mussels are finished steaming, use a slotted spoon to transfer them to serving platter. You can spoon some of the steaming liquid over them if you like, but be sure to serve them while they're still hot. If you prefer, you can serve the mussels directly from the pot that you steamed them in. If any of the mussels haven't opened during steaming, discard them.
Summary: Pour the wine, lemon juice, chicken broth, and red pepper flakes over the mussels. Cover the pot and steam the mussels until they open. Add the parsley and butter and steam for another minute. Serve the mussels while still warm.
