I am adding on and will increase my fixture count. The city will force me to increase my water main from 3/4 to 1-1/4 at about 5k including city costs.

Is there a way to add a 'reciever' tank much like an air system to help maintain flow when the city tests?

What in the world are you adding that the city would require a 1 1/4" service?

You wish to in stall a pressure tank on your water service? Why? What city test? All they will do is come out and put the new water line under pressure to look for leaks and if there is none you will have permissionb to back fill the ditch. What's your location where in will set you back five grand to run a new water service? Seems pricey to me. Please give us more details. Tom

Wheaton, IL. My net add is one full bath. The code has a WFSU worksheet that says currently I need a 1" line (only have 3/4") and after the WFSU worksheet says I need a 1 1/4 line.

I think it's a lot of $ and work to upgrade if I can avoid it. If adding a storage tank provides the flow I need the city will let me ride. The test is some kind of pressure test with all fixtures running (8 psi min)

Paul... there is a way to do what you are proposing... involves a large bladder type storage tank (volume) and a pump system to keep up the pressure... so it can be done.

Only thing is... if I remember correct... all the plumbing/tank/pump/electric/permits and labor came to about $5000.00 *frown*.

We had to do this for a commercial restaurant that had another plumber come in and install all new flushometer type toilets and urinals... then fired all up... and yup... you guessed it... NOTHING happened!! There was only a 1" main coming into restaurant. We hooked up large well tank and a booster pump... that did the trick (I am simplifying, of course).

We then had to change a lot of the piping over to make codes enforcement happy... was a lot to do.\

Talk to some of the larger plumbing companies in your area... *free estimates*... they should be able to help you.
