We have a 40 gal gas water heater. The second shower of the day gets stuck taking a lukewarm shower. What's up with that? Shouldn't 40 gallons be enough...?

Also, while doing dishes with the washer machine on, I lost all hot water to the sink. Turned very cold.

What can I do fix this?

You didn't say if this is new, or if it was working and has changed recently. If this is a new unit, check the temperature setting. It may just be that you have it set too low, and there's not enough hot water.

This is an older water heater. I've lived in the house 6 months and the water problems seem to be new ones. The temp dial is set on hottest.

You can get a check valve to control the temp changes. As to running out of hot water. When my teenage son gets done there is not a drop of hot water in the house for a couple hours. I don't think a 100 gallon tank would help. Check your temp setting on tank. Just remember setting up the temp will take life away from your tanks life span and the cost of utilities are at a all time high.

The tank heating element or thermostat might just be going bad. You usually can replace them without replacing the entire unit.

If the tank needs replacing, though, you might consider a "tankless" water heater, which heats water as it is used instead of in a huge and inefficient tank that can run out of hot water. The only downside I found (which prevented me from doing it, myself), is the electrical requirements. They typically require 60 amp circuits, which will ususally require you to run new wire. (Rather impractical in my condo where my circuit box is behaind a different apartment).

But the upshot is that they supply endless hot water and take up FAR less space that tanks. They also only heat the water when you use the water, eliminating all the energy reqwuired to constantly keep a tank of water hot, even when you do not use the hot water. A search for "tankless water heater" on yahoo or excite will give you several websites of tankless water heater manufacturers.
