Repair A Leaking Outdoor Tap

Outdoor PLumbing

Outside water spigots are one of the most common sources of water leak around the home. Do you need advice about how to repair a leaking outdoor tap? Sometimes they only leak when the water is turned on. In more extreme cases they leak all the time, sometimes a small drip, other times a serious flow. But all these problems are easy and inexpensive to repair.

If the spigot only leaks when the valve is turned counter clockwise, it may well be just a worn rubber grommet at the base of the valve stem. Like most rubber washers they eventually get compressed or develop small holes.

That’s easy to fix with a cheap, temporary repair job. Remove the nut that fits onto the spigot in which the stem sits. Grab a foot long length of Teflon plumber’s tape and wrap it around the base of the stem behind the nut. Get the tape in as far as you can and wind it over and over itself. Then tighten the nut to compress the tape back against the washer. That will stop many small leaks.

Be sure to check the other side of the pipe to which the spigot attaches, though. It’s possible to plug up one leak, only to cause the water to find another way out. If there is more than one hole, water will now drip inside the house. Not a good situation.

For more extensive leaks, replacing the sillcock (as it’s called) is generally fairly easy. It may require two people, though – one on the outside of the house and another in the crawlspace where the pipe enters the house.

Shut off the main valve to ensure no water will flow when you remove the old spigot and sillcock of the leaking outdoor tap.

The sillcock that supports the spigot is usually a 10-12 inch piece of threaded pipe that winds onto a water supply pipe inside the house. It takes only moderate force to unwind it in some cases. For those that have been on a long time, small amounts of oxidation can cause the sillcock to be stuck on firmly.

For those cases, a good pair of vice grips or a pipe wrench can be used on the inside of the sillcock. The threads are usually grooved in front of a nut that is an integrated part of the pipe leading to the outside spigot. Attach the wrench firmly to the ‘nut’ to ensure there’s no slippage. You don’t want to strip the metal smooth.

Give a good yank while keeping the pipe to which it’s attached still. That can be accomplished by using a good pair of wide-jaw pliers gripped and directed in the opposite direction. It’s important not to twist the pipe the sillcock threads onto, since it can be broken. That would lead to a job requiring welding or replacement of an entire length of pipe.

Sillcocks are usually no more than $10, even the anti-siphon style that prevents trapped frozen water from breaking the pipe. They screw back on easily. Just wind on a length of Teflon plumber’s tape in the right direction first. Make sure the tape is stretched tighter not loosened as you wind on the new sillcock.

Anti Siphon Valve Installation To Protect Plumbing

plumbing tools

You can use anti siphon valve installation to protect plumbing. Anti-siphon faucets are a must have for homeowners who live in cold winter climates. For just a few dollars you can avoid having to replace an outdoor spigot due to low temperatures. Let’s take a look at how an anti siphon faucet works.

In areas where winter temperatures get below 20F/-7C, it’s possible for trapped water in the spigot and sillcock to freeze and expand. The figure is approximate. It’s certainly possible for that same water to freeze at 32F/0C, but heat from the house helps lower the ‘danger point’ temperature somewhat.

Protect Plumbing From Freezing with Anti Siphon Valves

That ice now presents two possible problems, similar to those that cause pipes under the house to sometimes burst in winter.

The ice takes up more room than the water did. You can test that by filling a cup exactly to the rim with water then putting it into the freezer. You’ll note that the ice sticks slightly above the rim. That extra volume is no problem when the top is open. But when the water/ice has nowhere to expand, it raises the pressure on the container. Raise it enough and you can break a seal.

The major effect, though, is due to the fact that the pressure builds up beyond the ice block. Air and water have nowhere to go. The air is compressible, but any trapped water will create high pressure on the internal parts of the sillcock and spigot. Even strong metals, made more brittle by the cold anyway, can be split. Plastic and cold-hardened rubber are doomed.

When the weather warms again and everything melts, you now have a spigot with a crack. If it doesn’t leak spontaneously, turning it on will guarantee a drip or worse. This is when you may require anti siphon valve installation.

An anti-siphon spigot contains an additional mechanism beyond the ordinary outdoor water faucet. Hoses attach like normal, but inside and out they have features to prevent the spigot from bursting due to ice blockage and expansion.

A few things help prevent the anti-siphon spigot from cracking like an ordinary one.

The seal/valve that actually shuts off the water flow is further back in the sillcock – inside the house, which is warmer. That helps prevent cold temperatures from reaching the water. More helpful still is the ability of the sillcock to withdraw water away from areas where ice buildup can be a problem. It keeps the water from remaining near seals that can be frozen and cracked by low temperatures.

But most importantly, the design of the sillcock/spigot allows for the relief of pressure for any ice that does form. It gives a place for expanding water to go when pressure builds up in other parts of the sillcock/spigot.

Even so, in warm conditions and with normal use, it’s possible for anti-siphon spigots to leak out the top pressure-relieving spout or elsewhere. Kits with replacement seals and other internal parts are available for a few dollars. For those who prefer to repair rather than replace, or if the other end of the sillcock is difficult to access, these kits can save money and time.

What Is The Best Plumbing Pipe Leak Sealer?

What is the best plumbing pipe leak sealer? What are the best methods for preventing plumbing leaks – Plumbers Putty or Pipe Tape?

Sealing pipes and hoses during plumbing projects is critical. But how to do that correctly can be a little trickier than you might think.

The first tip follows the old mechanic’s rule: the right tool for the right job.

Plumbers Putty or Pipe Tape?

Select sealant according to its proper purpose. Use plumber’s putty for securing sink flanges when installing a garbage disposal unit. Use special-made toilet bowl grease to seal the base of the bowl to the trap (the hole or pipe out which the water is flushed). Use silicon caulk for shower pipes and spouts. And so on.

Never be tempted to substitute, for example, PVC pipe glue to seal a flange or sink where plumber’s putty is called for. Don’t use it to secure hoses. You’ll never get them loose again and, someday, they will have to be replaced.

Be sparing but not stingy.

The right amount of plumber’s putty, say a 1/4 inch bead around the rim of a newly installed sink, makes for a good seal. Use too much and you have an unsightly mess. Too little and you can end up with small holes or cracks that lead to leaks.

Remove any excess before it can dry, but take care not to wipe so strongly that you take away what’s supposed to be there. Also, excess sealant, whether plumber’s putty or silicon caulk, can leave ridges that give you something to bump against with a pan or knife. That can lead to tearing. Simply wipe the excess with a finger or slightly damp sponge shortly after application. Then, carefully wipe up any smears before they dry.

Be generous with Teflon plumber’s tape.

Teflon plumber’s tape is a great plumbing pipe leak sealer. It is possible to use too much, leading to small channels through which water can escape. But it’s rare. It’s extremely flexible and compressible. That makes it hard to overdo the job. However, if you wind on too much it can make fitting on a new hose or threading a pipe difficult or impossible.

Wind it in the proper direction.

When fitting on a hose, it doesn’t matter which way the tape is wound. But if the project calls for threading on a pipe, twisting can undo the Teflon tape. Wind the tape so that the tail points in the direction you will wind onto. That way, as you tighten the fitting, you’re stretching the plumber’s tape further. That leads to a good tight seal, rather than loosening the tape and making it useless.

Avoid torn ends.

Sometimes it will be a lot easier to simply stretch the tape until it breaks or tear it with your teeth. When you’re under the sink on your back with only one hand, the temptation to do that is large. Resist it. Sometimes you’ll get away with it. Many times, it will lead to re-doing the job after you’ve already tightened on the new fitting.

A clean end at the beginning allows the Teflon tape to seat into threads without leaving ragged high spots. Ditto on the tail. In either case, a ragged edge produces an uneven layer that will encourage small cracks. Water drips are not far behind.

Use sealants and tape according to their design and you’ll have a well-sealed hose or pipe. That eliminates water damage and messes… and the need to re-do the job.

Plumbing Tips for Preventing Pipe Freeze

Plumbing tips

As winter approaches on chore to make sure we do is to take steps to avoid having your pipes freezing in the colder nights. Pipe freeze isn’t the only problem.

After all, copper pipes can get to temperatures far below the freezing point of water without cracking. But too often it is accompanied by an ice blockage inside the pipe. That can lead to a pressure build up that ultimately bursts the pipe. Not only do you lose the ability to get water from the faucet, but now have the larger problem of clean up and repair.

In many homes, the odds of a burst pipe in winter from low temperatures are very low. But others have exposed pipes in crawlspaces or elsewhere. It takes only a modest opening around the base of the house to let in winds that can chill pipes to sub-freezing temperatures.

Even without that exposure, temperatures below about 20F/-6.7C present higher odds of ice forming inside pipes that will plug them up. Fortunately, to prevent that is usually straightforward and typically very inexpensive.

One old-fashioned remedy to avoid pipe freeze still works well: opening up the faucets to a slow drip.

Running water is slightly less susceptible to freezing than still water. But the main effect comes from simply opening the valve. That allows air and water to move, reducing any pressure build-up in front of the ice blockage. That gives the pressure ’somewhere to go’… somewhere other than pressing out the sides of the pipe, i.e. causing a break.

But there’s another old-fashioned saying that’s useful here: an ounce of prevention is worth a pound of cure. Preventing the pipes from getting too cold in the first place reduces the odds to near zero of having a break.

One way to accomplish that is to wrap them with low-cost insulating foam.

The foam itself supplies no heat. But it helps the pipes and water retain any heat they have. Water and pipes at, say 35F/1.7C, will tend not to go below freezing if they retain the heat present in the water and pipe before the temperatures outside dipped.

The foam comes in different forms. One popular style is a long, flat rectangle that curls into a cylinder. The cylinder formed is the circumference of the pipe. That makes it easy to wrap the pipe along its length and simple to cut the rectangle to the proper length and/or width.

If you want to prevent pipe freeze try this tip. It’s inexpensive, easy to install and easy to replace.

Another method is more costly and a little more difficult to install. But it has the advantage of protecting pipes no matter what the temperature. Foam will only retain heat up to a point. Some is always lost. Installing a heating system for the water pipes is as sure a thing as possible.

There are two basic types: wires or tape along the pipe, and a circulating system.

The first type is simply a wire or tape containing one that sits along the surface of the pipe. Electricity passes through it and heats the wire, which transfers heat to the pipe and the water inside. Costs vary, but if it’s properly installed the method is nearly foolproof.

The second type is a little more expensive, but uses existing facilities. Sometimes it’s already built into the home. In this technique, hot water from the water heater is pumped slowly through the pipes. Cold water is circulated back into the heater. The system operates automatically via an in-built thermostat and pump that is put in the water line.

It costs a little more to run, because the system heats and re-heats water that isn’t being used. But it is the surest way to prevent any ice blockage. Any ice that forms will be quickly melted by the warm water before it can become a problem.
