I have a backflow valve, which I drained for the winter, but the
frozen water cracked the pipe at the shutoff valve.
Unfortuately, on the LHS, I have a crack in the metal part that
attaches to the backflow value to the plastic piping. Where can I
purchase just that one piece [2"x2" with the shut off valve], or do I
have to buy the whole thing? What is it called?
I get my city water, which has a meter. Is there an attachment which
would allow me to shut off the water going into the house.
Can I just get away with putting a 2" hose clamp and some "steel hard"
epoxy on the crack?
I think it is called a ball value
I think it is 2"
Is it easy to take this apart and replace
How easy is it to disable the incoming water supply?
It is called a
2 inch tapped ball valve with test port
Is this standard for piping? Are the threads standard?
What's the downside of using one that is not tapped, like the one on
the outgoing end?
I would think a tapped one would give you a better seal.
I just went out an measured my pipes. Even though my pipes are 2
inches, the pipes on the backflow preventor are 1 inch.
Does anyone know if the central unit (the backflow preventor) is the
same for all 975xl product line, the only difference being that the
ball valves are different, or if they indeed make this model bigger
and stronger for the different dimensions?
If I replace the ball valve using ones from a hardware store which
don't have the tapped test leads, is this going to be a problem when
they come out and inspect my back flow preventor. Do they use the
test leads to hook up to the connector.
I said that I bought some Epoxy Weld (carton states that it works for
up to 2000psi). Do you think it will hold? How long do you think it
will hold for 20F-110F temperature swings?
Does anyone know if I can reweld the breaks in the lines by taking it
to a muffler shop? Any idea how much that will cost and it it is
worth it? Do you think an amature can reweld it?
Will a butane torch get hot enough to bond bronze?
Has anyone had any experience servicing his back flow preventer?
I replaced parts (1, 15, 16) of the
wilkins 975xl 1 inch,
but I still have water leaking out (1 gal/min) the square hole right
by part nu 15 in the diagram
Do you think replacing the spring #17 would make a difference?
I did not see any damage to the funnel shaped device, but maybe it is
too small to visually see?
