68 Pa. Stat. § 250.302
Personal property located upon premises occupied by a tenant shall, unless exempted by article four of this act, be subject to distress for any rent reserved and due. Such distress may be made by the landlord or by his agent duly authorized thereto in writing. Such distress may be made on any day, except Sunday, between the hours of seven ante meridian and seven post meridian and not at any other time, except where the tenant through his act prevents the execution of the warrant during such hours.
Notice in writing of such distress, stating the cause of such taking, specifying the date of levy and the personal property distrained sufficiently to inform the tenant or owner what personal property is distrained and the amount of rent in arrears, shall be given, within five days after making the distress, to the tenant and any other owner known to the landlord, personally, or by mailing the same to the tenant or any other owner at the premises, or by posting the same conspicuously on the premises charged with the rent.
A landlord or such agent may also, in the manner above provided, distrain personal property located on the premises but only that belonging to the tenant, for arrears of rent due on any lease which has ended and terminated, if such distress is made during the continuance of the landlord's title or interest in the property.
