My question involves landlord-tenant law in the State of: VA

I hired a plumber to fix my shower (only hot water would spray out) and the landlord will not pay for the repair because he said the plumber "adjusted" the shower, when in fact the plumber "repaired" the shower.

The shower has a cartridge that had internal parts that were frozen together and the plumber took them apart, cleaned them, and reassembled them.

The landlord said he is only liable for repairs and not adjustments. Is this semantics or is there really a difference between "adjustment" and "repair."
