Southside plumbing installed a new laundry sink basin in basement. Hooked up to existing drain line, and ran new PEX water lines. Hooked up and tested for leaks, and secured to the floor. We also installed a new main valve tree, and set pressure to approximately 70 psi. We also installed two new shower cartridges, which were delta ball style, in both upstairs bathrooms, and tested for leaks.
