The existing gate valves may or may not work for their intended
purpose... I never turn them off because of the stigma associated with
them (they are often seized open, or the packing nut starts leaking
once you turn them, etc). But to avoid un-needed problems with burst
hoses, I want to be able to shut the supply off except when in use.

I could theoretically get access to replace the existing valves, which
would be the best solution but it would be a lot of work. Like many
home owners, my spare time has a supply/demand crisis (thanks to the
leaky roof, the leaky barn, and the leaky patio door ;-). So I'm
looking for an easier alternative.

That can be a problem with gate valves. On the other hand, there are
a zillion of them around and working reasonably well. Unless they are
in real bad shape, I'd just use them. You can also replace the
packing and washers, etc. Another option, which is what I would do
if I were concerned, is to get the electric type valves that open/
close automatically.

If the gate valve are the "threaded" variety why not just turn off the
water supply, unscrew the gate valves & install threaded ball valve.

Or are the current gate valves sweated in place?

If clearance & orientation needs to be modified you can use close
nipples or street elbows.

Those garden hose ball valves are not the correct solution, in fact
they could be a source of failure themselves.

If you're worried about a potential burst hose, I'd do a proper ball
valve installation or consider "auto shutoff" supply lines

There's also compression mount ball valves.

The purpose for ball valves is to allow full, unrestricted water flow. If
you put one inline with an angle or globe valve, you've still got the
restriction of the other valve. What do you accomplish? Not much.

Like many others, I want to replace the gate valves on my washer
supply lines with proper ball valves. I'm comfortable with sweating
copper pipes where I have good access, which I do not have in this
case. So what I'd like to do if possible is put a ball valve directly
on the outlet of each existing gate valve, and then attach my supply
hoses to the ball valve outlets respectively - all using threaded
components.

I realize this will involve a variety of adapters and fittings, if
it's even possible at all. Can someone privy to plumbing terminology
help me come up with a bill of materials to hand to the local parts
counter? Or are there compelling reasons not to do it this way?

Thanks!
