Plumbing codes ensure the plumbing systems are up to the required standards. Plumbers‘ inspections are carried out to ensure the codes have been complied with. The video shows some plumbing code violations.
The washing machine drain plumbed in 1½-inch piping is a violation. The new code specifies that pipes and p-traps should be in two-inch piping. The standpipe must be between 18 to 30 inches in height and between 6 to 18 inches off the floor.
A lack of protection plates is another violation. These protect pipes during drywall installation. Another infringement is installing a sanitary tee on a horizontal drain line as it causes resistance and eventual blockage.
A 2-way approved cleanout is required on a main stack for cleaning and maintenance purposes. Another requirement is for the toilet rough-in to have 15 inches of clearance from the flange’s center to the finished wall. Another violation is plumbing a vent below the flood level of a fixture. Vents should be 42 inches off the ground, or 6 inches above the highest fixture for it to be up to code. If there’s a blockage, you wouldn’t know, resulting in serious damage.
Always stick to the latest plumbing codes. Failing plumbers’ inspection can have serious consequences and lead to awful plumbing issues.
