The pipe that feeds my underground sprinklers is leaking like a sieve at the location of the red arrow (gray plastic part). Is there an easy fix? The gray part seems bound to the black hose, so it can't be tightened.

If it needs to be replaced, what parts will I need?

Hello southwestern homosexual.

What you have there is a black plastic water line clamped on to a barbed fitting and then at least one more threaded fitting before the T that the valve is installed in.

You need to remove those few clamps holding the black plastic pipe. Might need to cut the clamps, I can't tell the style from your picture. Take all those threaded fittings all apart, you'll need wrenches. Clean up the threads. If none of them look damaged you can reuse them. Get some pipe thread dope (this is different from Teflon tape) and slather it on the threads and tighten them all back together until it feels like they don't want to tighten any more, then tighten each of them another half turn. Clamp it back on the black line using stainless worm drive clamps (these are removable). Helps to warm the black pipe up with a heat gun or torch. Check for leaks.

You may choose to simplify the parts that have been used or replace them with new parts, but I can't advise you on the specifics without seeing what they are. Worst case, take the whole jumble of shit into home depot and ask them which parts you need.

I'll get some of that pipe dope and see what's what. Thanks bro

>> No.1833411

It might be as simple as just needing a new gasket. Yes, unscrew it to see what's in there. I would personally use plain old teflon tape over the thread dope because it will create less mess and you honestly don't "need" dope for this. But the thread seal is more of a minor detail.

Another thing you could do is replace the entire fitting if you want to take off those hose clamps. Up to you.

>Use teflon tape not thread dope
I want to believe you because the gray coupling might be toast and I might need to undo everything and put in a replacement... Is thread dope going to solidify and fuck shit up if I need to replace shit?

Oh, weird. In the US the only houses I've seen slathered in stucco are in hot climates.

>>1833463
Teflon tape is intended as a lubricant to seal pipe threads whose virtue of sealing is tightening enough into their own tapered threads. Pipe dope is intended to be a sealant as well as a lubricant. For this reason, I recommend (and personally use) pipe dope any time pipe threads are suspect/a problem part is being put back together. Yes, you can still take it apart - we're talking about stuff that gets taken apart with wrenches anyway..

LEAKY PIPE? TRY FLEXTAPE!! FLEXTAPE IS THE ONLY WATERPROOF TAPE THAT CAN TAKE A BEATING AND STILL HOLD WATER! JUST LOOK AT THIS BOAT. I REPLACED THE BOTTOM WITH A SCREEN DOOR AND COVERED THE SCREEN WITH FLEXTAPE. LOOK WHAT HAPPENED WHEN WE TOOK IT ON THE LAKE! NO LEAKS!! BUY FLEXTAPE TODAY!!!
for real though, if you try flextape, post an update if it actually works. I am curious.

What do you use to seal gas tank-regulator connections? I've just been using bare brass and it doesn't seem to leak, not that I leave my tank open for long times.

No, you're doing it right. It's a metal to metal seal.

There are some people who either don't put the reg on right or fuck up the metal to metal seal (the smooth brass gland end) by beating their equipment to shit because they think it makes them manly.

90% of these people suggest teflon tape because "it seals plumbing, so it should work on a 3000PSI CGA fitting.

Threads aren't perfect, especially on iron pipe shit because of the way they are cut.
In old days there were using thread of weed with some sort of lubricant (animal fat, grease, even paint). It all is a dirty mess. PTFE tape combines both, weed's ability to caulk, and fat's ability to lubricate. When you tighten the tapered thread, PTFE tape is compressed, and this makes the seal. In case of straight thread this will not happen, unless you wrap it thick.
As for caulking ability, thread is better sealant of water, since it expands a bit and allows 10-30 degrees of adjustment. Teflon - no, once it is compressed, it won't expand.
Teflon also can be used of non-tapered threads in order to prevent farmers threadlocker from locking thread. But if you wrap 9000 turns of teflon on straight thread that relies on rubber gasket, you're retard, since gasket is sealing in this case, and thick layer of teflon will just make it harder to squish the gasket.

I used Teflon of aircon with leaky schrader valve. Still no bubbles. So it works. I use it in heating mode and pressure can get as high as 40 bars.

It might be a good idea if you have shitty scratched surface on penis (idk how it is called).

You don't. They have something like flare that relies on good machining.

There will be a location where the water comes into your house from the city. Depending on your area that location could be your basement, or in an access out in the street, or in an access in your lawn, or on the outside of your house. They're pretty easy to shut off when you just can't find the shutoff you need in your house. But honestly you shouldn't be fucking with them if you have no idea what you're doing -- if one is old and corroded and you break something like that in a basement... oh man... RIP basement.

Unless of course you're on a well, in which case shut off the pump.

Unless of course you're on a well and the well is on the top of a hill higher than your house, in which case, find the first shut off that comes into the house.

if those sprinklers are on a timer, you may want to consider adding a $20 arrestor

Pipe with a cap was an old way to fix water hammer. You have to drain the lines sometimes to keep those pipes full of air but it isn't unheard of.
