I get hot water to the kitchen sink but not to either

I get hot water...

I get hot water to the kitchen sink but not to either bathroom shower. When the hot water is on in the kitchen sink the heater has a continuous red light, when I turn the hot water on in the shower the red light is blinking.

Contractor's Assistant: How long has this been going on? And how severe is the problem?

It has been touchy for a while but there has been no hot water to the showers for two days. It's severe b/c we have 2 five year olds.

Contractor's Assistant: Do you plan on doing the work yourself?

Welllll - i don't know if I'm able.

Contractor's Assistant: Anything else we should know to help you best?

Suggestions, please. Any idea why it will supply hot water to sink but not showers.

Hi my name is ***** ***** I have been in the plumbing field for over 20 years. I will be glad to help you today. Do you have hot water at the bathroom sinks? Do you have a hot water circulation system and are you having any remodeling done in the baths?

Customer reply replied 1 month ago

Customer reply replied 1 month ago
Did you receive my last message?

Sorry for the delay. Is the water not hot enough or totally cold?

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
In the shower it's totally cold.

How old are the shower valves? How long have the showers been cold? Is the flow very slow coming out of the showers?

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
The bathrooms were remodeled about a year ago. The water stream is sufficient. The showers have been iffy for some months but cold now for 2 days.

When you turn on water at any sink, is the water instantly hot or do you have to wait for hot water? How long does it take to get hot water there? If you turn the bathroom sink on hot then the shower does the water in the shower get hot then?

The water to the sinks takes 10 + seconds to get warm/hot. Right now when I turned on the hot water to the sink then in the shower I got hot water. But, it didn't last.

Are the showers back to back and are they the closest to the water heater or furthest?

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
One is close, one is farther away but they are essentially back to back.

Do you have one of these things somewhere, maybe on the water heater? click here

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
I do not.

Is your water heater used for heating also or only hot water?

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
No, just hot water. We probably need a new ones?

Not even heated floors?

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
Oh, no. We live in Hawaii.

So, I do not think there is an issue with the water heater. It is almost certainly in one of the shower cartridges. Are the shower valves both single handle and when you turn them on would they start off cold then the further you turn the handle the warmer they get or opposite?

Ask Your Own Plumbing Question

When they did work correctly...

Ask Your Own Plumbing Question
Customer reply replied 1 month ago
They are single handled and start cold then hotter as you turn the handle.
Customer reply replied 1 month ago
We have only lived here since Christmas but I don't think they've ever worked correctly. Pretty sure I will have to have a plumber come in. I am not the least bit handy.

The issue is one of the shower cartridges. One of the shower cartridges is cracked or defective and when turning on the shower it pulls the cold water through the cartridge. There is a little more water pressure on the cold water side compared to the hot and the water will go to the point of least resistance. Still typing....

Ask Your Own Plumbing Question

If you find the brand name on the shower plate then have someone replace both shower cartridges that will solve the issue. Make sure they use the brand name parts and not Danco. The cartridges are likely Danco already. I have had that problem before with those.

Ok, thank you so much. I will have some knowledge behind me when I get the plumber here. Your service is great!!

You are very welcome. I am sure that plumbers are crazy expensive there. If you find the brand name on the plate and get the replacement cartridges for them (likely free from the manufacturer although time is not exactly on your side) a handy man can likely replace them too.
