After reading that Washing machine hoses, etc are statistically the
biggest cause of flooding, I would like to prevent this.
I currently have a standard washing machine wall box with 2 standard
multi-turn boiler water valves. I would like to retrofit a single
lever dual-valve shutoff in place of the 2 standard valves.
The house is about 10 years old, but I have no idea if the valves
are threaded or soldered in place. I'd have to rip out the drywall
around the Washer box to either hold the nut to unscrew the old valves
or to be able to unsolder the old valves.
1.) Is this a good idea?
2.) Could a plumber do all this including cutting out the drywall,
3.) What about a no-construction jackleg sort of solution which
would be 2 hosepipe-to-1/2"-adapters so that the dual-valve would be
installed outside the boiler valves?
Almost any plumber will be happy to hack some holes in your drywall.
Very few can/will make good afterwards ;-)
Just buy and fit some really good quality hoses (e.g. with stainless
steel braided sheath). Inspect regularly.
Alternatively, if you really want another electronic gizmo, consider
something like this:

I have a single handle washing machine shutoff I installed 25 years ago
and were I to do it over I would just use 2 ball valves. Cheaper and
allows you to do a very hot wash by turning of the cold water for
things like dyeing.
Get good quality hoses-the ones with stainless braid are less prone to
Definitely a good idea to install one, but are you sure that you can
train all the machine users to remember to shut the valve off when they
are done using the machine? And what happens if a hose decides to blow
from the water hammer when a washing machine solenoid valve closes, and
no one is right there keeping an eye on things?
You might want to consider using an automatic water detecting shut off
valve set like this one:
Using one of those systems takes care of the issues I raised, plus you
won't have to do any wall ripping or soldering either.
And, if you want to be really anal about it, you can push the "OFF"
button on the controller when the laundry is done. <G>
will a floood do damage? with washer in basement on concrete floor who
with washer on 3rd floor WORRY.
do install properly a auto off valve, and for extra protection a washer
catch pan with drain line somew where like a washtub......
minimizes leaks and they cant do serious damage.
few people will remember to use every time even a single lever valve:)
I've seen these valves. I think the idea is to make it easy for home
owner to flick on the valves to wash, and flick off when moving the
clothes to the dryer. I think many insurance companies would be happy
to see these in homes.
You will have to talk with a plumber. Get all steps in detail,
including clean up. Dont' assume they clean, since you are paying
them a high price to use your vaccum.
Installing a single control valve won't prevent
anything. You need to turn valves off each time
you finish using the washing machine. If you
can't do it now with two valves, you won't be able
to do it with 1 valve.
If you really want to prevent possible flooding
you need to install solenoid controlled valves
that are normally shut and only open when the
washing machine operates. The solenoids probably
needs to be controlled by circuit of the main
I don't know how you were raised, but it is much easier
to turn off one valve with a touch of the finger than it
is to turn off 2 valves taking several stiff rotations.
I just installed a dual toggle valve and, while I don't
always remember to turn it off, I do the majority of the

You're right in that it only prevents catastrophies that would have
occured while not washing and only if I remember to turn it off. A
battery operated alarm connected to the laundry room door closure and
valve would be a simple failsafe reminder.
I'd be much more likely to turn off a single lever valve (2 seconds
flip VS 60 seconds of cranking). Also, in my limited experience,
frequent rotary boiler valve operation can result in valve seal
failures due to overtightening, etc.
I have just found an electronic cutoff valve (watts) controlled by
the washer so it'd be simple. It also comes with a moisture sensor.
And an adapter kit is available for a dual boiler valve box. Total
list price about $270 --- probably less than a full plumber retrofit
of the dual valve cutoff.
However, it seems to be a case of nearly too complicated for a
protection device, and could easily to fail within an estimated 20
year lifetime. It requires a surge protector, however an external
surge protector would not protect against a voltage spike between the
water pipes and power line - a likely condition in a lightning strike.
This could require talking the wife through how to bypass the device
if it is hit by lighning while out of town.
actually not true. most failures are burst hoses. minimizing time they
are pressurized by auto valve should help prevent a disaster all the
time.... less wear on hoses
deally a electric valve that turns water off when washer isnt in use
PLUS turns water off at any time if a leak is detected.
Your concern appears to be a auto valve damaged by a power surge.....
add surge protection to your main breaker cabinet and make certain
everything is well grounded.
a serious power surge can cause way more damage than being unable to do
laundry, most folks have a ew days worth of extra clothes, time enough
if your out of town for a plumber visit...... or laundrymat. or phone
