    What brand do you guys use and are you satisfied with the performance? I'm getting tried of the wire nut not "Grabbing" and all the silicone coming out and throwing them away. Thanks

    If you are using King Connectors, you need to make sure that the wires are twisted together, and then trimmed off so that they are the same length, and don't over tighten them as they have plastic threads. And don't expose more than 1/2" of wire.

    Wade Connectors use Scotch wire nuts with metal spring threads. Twist them on the wire and then insert into the grease filled case, lay the wires out to the sides, and snap the cover closed.

    Or do like some of my more progressive competitors and twist the wires together, wrap them with a piece of electrical tape, and dip thom in blue potting compound. I love these guys. Makes for good amount of service calls.

    With the silicone filled wire nuts - as well as with dry ones - if they're too big, they will slip. I think the tendency is to get them a bit too large for some reason. You only need larger ones for connecting the bundle of ground wires together.

    I've found that if I have a problem, I can generally make things work by twisting the wires together, folding this bundle back upon itself, and then reinserting into the wire nut. Of course, the right tools and right parts make less work, eh?

    I wonder if anyone ever tried filling dry wire nuts with Vasoline?

    In a pinch, you can take a short piece of wire and twist it into the bundle to build up a little bulk. Especially when the previous installer used 18ga or less wire on the install.

    Less than 18ga? Yes, I have seen systems wired with thermostat wire which is 22ga and this was done by professional irrigator's!

    I've found some made by 3M, they have 3 inlet holes for up to 3 wires, or as many as you can fit. They are clear as to make sure you have the wires all the way in. Then once wires are fitted, use a pair of pliers and clamp down the metal tooth. The tooth cuts through insulation of wire, so you don't even have to strip the wires. Very quick installation and never had a problem with them not making a connection or coming loose.

    I get mine at the local sprinkler supply warehouse, can't find them anywhere else.

    About the same price as wire nuts too.

    We have great luck with DRYCON wire nuts- Just be sure to use the right size for the size wire or number of wires you twisting

    We use Harmony Products (TKHP) wire connectors with success. We have also used DBY's with success also. Have not had any problems with either. We used to use the 3M connectors that cleancutccl mentioned but they are water resistant and not waterproof and have had to replace several.

    the 3 m's we usw are water proof.
    they have the yellow wire nut, and a tube filled with grease that's anout 3" long.
    you twist the nut on , push down into the grease, and the nut is a few inched down in the grease. then flip the cap down.........

    We use the same 3M wire nuts and are extremely pleased...much easier to work with than wire nuts we have found. VERY tight secure connection. We actually found someone selling them on eBay last winter. We bought 2,000 connectors for $150. Works out to be about 7 cents per connector.
