First turn on tap it sputters for a few seconds before running smoothly . Also toilet make a swooshing sound after flushing.
Possibly air getting in pipes?

Was the plumbing opened anywhere recently so that air could have gotten in. Shortly after a repair and the water is turned back on, it sputters like that but other than that, I can't think what the cause could be. It may be a good idea to have the water pressure checked and see if it is higher than 60 p.s.I.. Maybe if the pressure is too high it could cause some sputteri ng.

Does this happen hot, cold or both. Single handle faucet or two handle faucet?

Thank you I will get the water pressure checked
