70 lbs, you must have city water, were lucky to get 30 lbs out here in well country. Most mixers sold now days are restricted, water saver devices, but most are also in the ends of faucets. You might not be able to get more pressure out of it, but if you look at the diagram of the faucet, you might see something that says, water saver, or restricter. If it can come out, take it out. Hope this helps.
