    I have already done the 45 from a sleve on a 1 1/4 pipe. Does it get much harder than that?


    And, how do you feel about those extension couplings for pvc?
     
  4. Do not use on main lines...I have cut out 2 leaking 1 1/2" slipfixes in the last week.....

    Why do you think they are bunk?
     
  6. They rely on o-rings as seals and they leak 90% of the time.
    They allow movement of the main line since they have a telescoping action.
    We maintain a system with a 2" main and I know for a fact they used a slipfix on the main because every time I open a isolation valve on the main I see the isolation valve move.

    Here are two pics of 1 1/2" slip fixes I have replaced in the last week because they started leaking....

    Slip fixes=not the best solution for longevity.

    O-rings not securely attached to PVC=leak=bad.

    Like London said ( I am agreeing that they are bunk).

    Good to see you back in the action here and to hear of your adventures.
     
  10. If you have pipe coming from a sleeve, if I understand you correctly, you need to concrete it in at each fitting just outside the sleeve to keep it from shifting. I'm on board with the slipfixes being junk, 4 ells are better. Comp couplings aren't any better. they make 22.5s for some situations that a 45 would be to severe. Also you can double ell to get the slope angles right. hurts pressure a little bit. What brand of glue you using? Using primer? How are you cutting? Hacksaw or fancy ratchet cutters? Learning to make straight cuts? Does Brandon manifold or zone valves individually? can you keep track of multiple pipe runs in a ditch? Wearing gloves or doing it bare handed?
