    First off I want to say I love Netafim, I think it is the best way to water tree/shrubs/gardens in the right applications..Anyhow I love it, push it on customers when possible..

    So I get to my parents house today which I have installed many zones of drip with the proper reducer/ filter/ 17 mm 12' drip. I am adding on to a reducer filter that I have 2 and soon to be 3 zones running manually with 3/4 plastic ball valves..

    I go to the supply house today after work, get my material fittings, male adapters, blah blah blah.. So my Father says he has a small leak in the ground around the fittings where we have 2 ball valves installed...When I installed these 2 weeks ago no drips existed. NONE! Now, TODAY, I put in my third ball valve using my less than 1 second heat on the fittings. I figure the leaks would get fixed cause I would make a mini Ram manifold. Do it proper like, nice an even equally spaced ect so forth.

    Here is where the problem starts 3 times I cut out and re installed the manifold finding leaks on almost every fitting, 90's, T's, male adapters...
    I tape, use less heat, try every idea I can think of....So after I cut out the BS for the third time, I take apart the filter...Nothing wrong there. Then I figure check the reducer, when I turned on the water it went 15 feet easy through a 17 mm male adapter..

    What I think could be wrong.
    1. bad fittings
    2. the reducer (25 psi) is not working..since i don't have my flow gauge I can't tell pounds coming out.. But it shooting so far leaves me suspect...

    Any thoughts?
    This really stinks cause I push this product on all who will listen..I love it, still do...Im glad its @ my parents house so I don't look like a total Jackass.

    I am sure every one will tell me I am wrong but I doubt that it is pressure problem. many people around here install netafim with no filter, pressure reducer, or clamps on the drip fittings and feed it with 50+ psi with no leaks. I even called the northeast netifim rep to ask about this and he told me they only recomend the reducer to cover their a$$. I know the toro blue stripe drip even gives specs on pressure up to around 50 or 60.

    the only time i have had leaks is when i used the torch for a little too long and distorted the pipe. other than that I have no idea.

    Seems awfully rare that youd have leaks from all of those fittings. Also have seen Netafim without a reducer at the valve, with no issues.

    Man up, use those cannons to get 'er together without the heat. I have used heat a few times since coming to polyland. I likey very much.

    I've never heard of the heat deal. Just muscle them on the barbed fittings (make sure to get it right the first time:)) and they should be good to go. Sometimes I run into issues with a threaded connection x barb, sometimes use tape.

    I prefer using the barrel fittings that you insert the netafim into, instead of the barbed fittings.

    No leaks either :)
