Overview:3个常见的淋浴阀更换问题
If your bath or shower faucet drips, you can fix the old shower valve and faucet with a few inexpensive replacement parts. (If the spout and handles are worn, you can change them out, too.) But if it’s a new style you’re after or features like preset temperatures or anti-scald protection, it’s time for replacement. How to change shower fixtures and installing a new shower faucet is a straightforward process of connecting the new valve to the old pipes. Sometimes all you need are the manufacturer’s instructions and some basic plumbing know-how. But it isn’t that easy very often. This article will focus on three complications that installation manuals and plumbing books ignore.
- There’s no access to the inside of the wall.
- 旧管道是镀锌钢。
- 您想用单手型替换两把手水龙头。
Problem 1:No access panel
To replace the faucet, you have to work里面墙上。有些家庭有一个可拆卸面板中next room behind the faucet. If you don’t have an access panel, you might be able to replace the faucet by cutting a hole in the shower surround (Problem 3 below), but the best solution is to install a paintable plastic panel behind the faucet. You’ll find them in various sizes at plumbing suppliers, some home centers or online (search for “access panel”). Buy a panel that’s at least 14 x 14 in. If you don’t want to install a panel because it would be an eyesore, an oversized cover plate inside the shower surround is another option (Problem 3 below). If you already have an access panel but it’s too low to provide easy access to the faucet, you can install a second panel above the existing one.
Don’t try to position the access hole by taking measurements. Instead, remove the tub spout or faucet handles and punch a marker hole through the wall (Photo 1). If the wall is plaster rather than drywall, use a drill and a long bit instead of a screwdriver. Before you cut a hole sized for the access panel, cut a smaller hole (Photo 2). That way, you can see exactly where the pipes and valves are located and position the full-size hole for best access to them. Use the access panel frame as a template to mark the full-size hole. To avoid damaging the frame of the panel, install it after you’ve replaced the faucet

Problem 2:镀锌钢管
与铜或塑料不同，钢管与螺纹螺钉连接连接在一起。因此，您不能简单地切开冷热管。那将删除螺纹末端，您将没有可靠的方法连接新管道。
To preserve those threaded ends, unscrew the union fittings that connect the supply lines to the faucet (Photo 1). You can leave the spout nipple connected to the faucet and remove it along with the valve. If the faucet is connected to a showerhead, cut the “shower riser” pipe (Photo 2). This pipe isn’t under constant pressure, so you can reconnect it with a special coupler later.
Connect the new faucet as shown in Photo 3. To connect the cutoff shower riser, use a special compression coupler designed for galvanized steel pipe (called a “Dresser” coupling). For a better seal and easier installation, apply Teflon pipe sealant to the coupler’s threads and rubber seals. Run the shower and check the coupler for leaks. If you find one, tighten the coupler’s nuts.

Problem 3:Replacing two handles with one
淋浴水龙头更换
如果您有两把手水龙头，则最容易用另一个双手模型替换它。如果您想要单个手柄的便利性，则必须隐藏手柄留下的两个孔。超大的盖板就是这样做的。另外，它覆盖了一个访问孔，可能允许您跳过添加访问面板。请记住，如果不是不可能，使用这个较小的孔更换水龙头可能很困难 - 大型访问面板会使工作变得容易得多。您会在管道供应商店或在线（搜索“翻新盖板”）上找到超大盖板（约合23美元）。
To install a single-handle faucet, you’ll have to cut a hole into your shower surround. If your surround is fiberglass or acrylic, cut the hole using a jigsaw and a fine-tooth blade (a coarse blade causes more vibration, which can crack the surround). Apply strips of masking tape to the surround to avoid scratching or chipping the surface. Run the saw at full speed, but push it slowly and gently along the cut mark. If you feel the blade hitting a pipe inside the wall, stop immediately and continue past the pipe using a hacksaw blade.
To cut tile, use a rotary tool equipped with a tile-cutting bit (Photo 1). Set the cutting depth of the bit at 1/4 in. and make the first pass. Make more passes, setting the bit 1/4 in. deeper each time until you’ve cut completely through the surround. If you don’t own a rotary tool, you have a few other options: You can try a jigsaw and ceramic tile blade (about $5). These blades cut softer tile well. If you find that your tile is too hard, drill a series of 1/4-in. holes through the tile and wall using a carbide ceramic tile bit (about $5). Drill the holes close together so there’s little or no space between them. Then cut any material between the holes with the ceramic tile jigsaw bit.
