The best way I found to water tomatoes underground is some PVC pipe with holes drilled in it and then covered with one leg of panty hose and buried as deep or deeper than you bury the roots of your plants (by the time I set my tom's out they are usually buried at least 2 feet deep, I start from seed and constantly set them deeper and deeper so they develop huge roots). I also start the hole earlier and deeper than I am setting the plants and mix in some goat or rabbit manure, mix it with some of the soil (the plant roots will eventually find that food) and backfill.
Don't drill any holes in the above ground part of the pipe, just cover the top opening with some foil or a PVC cap to keep bugs and dirt out. The pantyhose will prevent the soil from clogging up the holes below ground and allow free flowing water and manure tea. I also add 3 Tbsp of Epsom salts to help add magnesium and other trace minerals. (not more often than once every 3 months)
If you are growing beefsteaks, then try adding one pipe on each side of the plant. To feed the tomato roots, you can cut a soda bottle in half and use it for a funnel, the opening will fit inside the pipe to make it easier to feed and water them. I also remove the suckers as I see them and if they are large enough, I root them in a small glass of water and plant them out too to add to my garden.
My largest tomatoes this past season were 18 inches around! (quite meaty and there were tons of them)

I have been using the PVC pipe watering method for the past four years on the same location - never rotating. I have always had excellent results. Nearly all of my tomatoes, this season weighed between one-half to one pound, and produced
an unbelievable quantity. I water about every three days.

Soaker hose works just as well and less work and inexpensive.
Need a photo to see just how this is done, please. i.e. the hole size. Thanks so much.

A question I have, is that can you plant the tomatoes in the same spot each year? I thought you need to rotate them.

Don't understand your construction on this. Where do you put the upper tube. Need diagram.

Chemicals used in PVC plastic have been linked to increased risk of breast cancer in women. Are you sure it is safe to use PVC pipes to water tomatoes you're going to eat and/or feed to your family? Is there an alterntive to PVC pipes we could use instead?

I am a little confused about your post. You said you start from seed and set them deeper and deeper. I don't understand that at all. Do you mean you start them inside? But then you say you set them deeper and deeper? Am I the only one who doesn't get this? Could you explain please?
