I don't have cold water anywhere in my house.
I just recently bought a house and since we moved in it hasn't had any cold water. When I turn on the cold water in the kitchen sink it stays cold for about 20 seconds then it gets hot. Then no matter what position the handle is at it stays the same temperature. My shower is the same way I can't change the temperature by turning the nozzle, it just stays at one constant hot temperature. The other day I noticed that the water in the toilet is hot too. What could be the problem here?
You have a cross connection. You should have got some kind of warranty when you bought the house. Since you don't know the history contact he seller to see if any plumbing work has been done lately. No? Then start closing of the stops, one at a time, to all one handled faucets. Close off each one and then try the cold water. If you haven't had plumbing work done the next likely spot is the one handled valves. Let me know the results. Good luck, Tom
The hot side is hot also. It just stays one temperature.
What are the stops?
Stops are shutoffs to each individual fixture. All sinks and toilets have shutoffs. Some tub/shower valves also have shutoffs.
The idea here is to shut off each shutoff individually until you find which fixture/valve is causing the cross connection.
If, for example, you shut the hot water shutoff off to the kitchen sink and then you run the cold water at the bathroom sink and you no longer have hot water coming out the cold side of the sink faucet then you will know that the kitchen sink mixing valve is defective and the cartridge will need to be replaced.
This test only applies to SINGLE HANDLE faucets/valves so no need to shut off shutoffs at two handle faucets... O.K.?
If your tub/shower valves cannot be isolated then test all other single handle valves/faucets and see what happens. If no answer the answer will be at the mixing valve of the tub/shower valves OR some other cross connection in the home.
Let us know what you discover... ;)
Thanks mark I will check that.
