at work we dabble with in floor heat.usually 2 or 3 of us install the tubing then the company subs out the rest of the job.we use the insulated tarp and staple the pex to the tarp.this should be an easy job but the pex stapler is a total piece of junk.the plastic staples constantly jam up in the stapler.just wondered how you guys secure the pex and is there a better stapler on the market?
