turning off water supply?

Brad G

hi im a little bit impaired when it comes to plumbing- I need a bit of help here- I want to change the washer in a tap- so i turned off the water mains outside- then opened up all the cold taps to drain them- but now boiling hot water is coming out the cold tap??? do I also have to shut off the geyser

Answer
The hot water water is finding a path through a faulty valve (tap) washer to the cold water side. Since you shut off the main water supply, it can only be the pressure from your hot water tank. Open the drain at the bottom of your hot water tank to relieve the pressure from there.

Are there any pressure washers that have its own water tank?

I am looking to wash the undercarriage of my car. I live in an apartment, and don't have access to a water source. I am finding it impossible to find a pressure washer that has its own tank. The few I found seemed to stop selling in the US (Nomad pressure washer comes to mind).

My car has a special paint, and cannot run through a car wash. I think I can use the self-service, but if there is a different solution, I would like to go that route instead.

Any advice?
Thanks for the advice William - I sadly moved into a big city for work, and all my friends have similar living situations :'(

Using a Hot Water Pressure Washer to get ice off of roof of house?

Minn_Wild

With winter coming up here in Minnesota, I was wondering how much it normal cost for someone to come out and get a roof cleaned off for a normal rambler with a Hot Water Pressure Washer?

Thanks for your time

Answer
I doubt you'll find any body reputable to do it.

It will cause more ice growth when the water freezes.

It could blow holes or find leaks in your roof.

The best answer is electric roof defrosters. You can also get electric defrosters for your gutters to melt the ice in them too.

Both are available at major home improvement places like Home Depot and Lowe's.

They are asy to install and have plug into extension cords. They turn on automatically when the temperature drops beyond a certain point. The last one I saw in an ad was set to trun on when it drops below 35 degreess fahrenheit.
