NOTE:  New clip design requires snap ring pliers (found at Harbor Freight ).
1. To begin the installation process, snip the ends of the silicone sponge at a sharp angle with scissors.
- See Fig. 1A
2.  Next, slide stainless steel clip onto sponge.  Crimp capture ring on clip slightly with pliers to secure clip on core.  This will help prevent rubber core from sliding through the clip when water pressure is applied. 3.   If this is a splice or transition point, after the clip is attached, snip the sponge straight about a few centimeters back, enough to make a secure knot, from initial cut.  Take care not to cut  internal twine.  Remove some silicone to expose the twine inside the sponge for creating splices or core size transitions.

- See Figs. 1B & 1C
4. After the silicone sponge is prepared, insert the sponge into your potable water pipes.  Secure clip to inside of pipe with snap ring pliers.  Silicone sponge should protrude slightly from pipe.
- See Figs. 2A & 2B.


6. If you need to extend sponge for longer pipe, tie the exposed twine from each core to one another with a good knot as you pull both cores together.
- See Fig. 3A

7. For maximum protection ICE-LOC® should be inserted to the full length of pipe that is exposed to cold temperatures.

Determine ICE-LOC® Sizing Needs

Prior to installing ICE-LOC®, determine what size of silicone sponge will be needed for your project
• 5/8 in. core (GREEN) - for 1 in. pipe
• 1/2 in. core (BLUE) - for 3/4 in. pipe
• 5/16 in. core (PINK) - for 1/2 in.pipe

Larger Pipe Sizes

An alternative for pipe larger than 1” is to use at least two green cores for 1.5 inch pipe and at least four green cores for 2 inch pipes. Remember, ICE-LOC® core diameter gets much smaller under city water pressures.
You can pull those cores one at a time or pull the cores together into the larger pipe. We do not offer clips for larger pipe sizes so we cannot guarantee the effectiveness of Ice-Loc in larger pipes.  Don't forget to have cut the ends leading end of the cores at a sharp angle so water can flow much easier over cores. See below how to anchor. Larger diameter pipes almost always reduce to 1 inch or smaller in the final end use.
See Example: For 1 1/2" pipes, place 2 green ICE-LOC® cores into pipe as you would with smaller pipe. With the 2 cores tied together, no clip is needed and the ICE-LOC® core will not fold back on itself.

Larger pipe is usually reduced down to a smaller pipe. At that point a single core can be tied to the 2 cores used for the 1 1/2" pipe as shown below.  Now a retention clip can anchor the whole section. Make sure the single core protrudes into the 1 1/2 pipe so the two cores are set back away from the reduced input to the 3/4 inch pipe so as not to impede flow. You can pull back green cores to take out the slack
- See Fig. 2

, you can use steel fish tape as used for pulling electrical wire through conduit to get core into a length of pipe.


Pipe Usage

ICE-LOC® can be used in pipes made of PVC Schedule 40 or better, Type L copper, steel or galvanized pipes. Type M copper can also benefit from ICE-LOC® during freezing conditions, but keep in mind that Type M copper typically has a very thin wall and may not survive many freeze cycles even with Ice-Loc®. If Type M is in place, using ICE-LOC® may help prolong the pipe's lifespan. Some form of protection is better than no protection.
Type M; is typically bought by home owners (economy grade) and not installed by professional plumbers when they are doing the plumbing. Not usually allowed by plumbing code for pipes under pressure.
Not recommended for Pex Pipe ( non-typical tubing sizes using barbed fittings).
Not for CPVC pipe as pipe sizes are as with Pex Pipe and pressure rating is  low.
Not approved for Fire Suppression Pipes.

Not intended for type M copper.

General Application Questions

1. Can I solder with ICE-LOC®?
The ICE-LOC® silicone sponge can withstand solder temperatures in copper pipes, but only the use of low temperature solder joints.  As long as the copper piping isn’t exposed to continued heating, ICE-LOC® will hold up just fine.  However, the silicone sponge cannot withstand applications that require the use of high temperature solders, such as silver solder (not to be confused with low temperature silver solder used to replace leaded solder).  These high temperature joints normally apply to industrial applications.  The ICE-LOC® silicone sponge can then be fished through the pipe after the high temperature joints have been made and allowed to cool down.  It is a good idea in all situations to tin all pipe pieces first, to avoid unnecessary exposure of core to continued heating.

Remember ICE-LOC® will not protect a copper pipe that already had a freeze split and was repaired by soldering.  The split can still open where it was repaired.  The damaged section must be removed and replaced with new couplings and a new piece of pipe. This is a repair that is normally done by a certified plumber.

2. What if I use a ball valve fitting (plastic valves such as PVC)?
A fitting that retains water, such as a ball valve, when closed, traps a small volume of water and is subjected to high pressures when frozen. ICE-LOC® can’t be placed in the valve ball, but the valve can be protected by drilling a small hole (3/16-1/4 in.) through one side only of the inner ball before using the valve. This allows ice to expand out of one side of the ball and into the pipe with ICE-LOC®. Pumps and other types of water retaining reservoirs must be drained or prevented from freezing. ICE-LOC® cannot be placed inside a pump.
3. What are additional techniques to install ICE-LOC®?
ICE-LOC® can be applied to a plumbing system by using a fish tape, commonly used by electricians to pull electrical wire through a conduit.  The tape is first inserted through the pipe and the ICE-LOC® sponge is attached to the end of the steel tape by the center twine.  The silicone sponge can then be pulled through the pipe.
Another method that can be used is attaching a piece of wadded up plastic bag material to carpenter’s twine and then blowing through with a compressor. 
Using a shop vacuum on one end to suck the twine through the pipe is an additional technique. then tie twine to Ice-Loc and pull it through.
