Pex pipe for infloor heating

Next, my husband took a can of orange spray paint and sprayed where the walls would be. Then we laid out the pex pipe for in floor heating. We did not know at that time if we would need it, but it was easier to do it now than later. To date, we do not have the in floor heating hooked up, but we have purchased a boiler and we hope to have it hooked up before next winter. The pex pipe was laid out in five zones so we could turn on and off certain zones.
