Sometimes its not the washer that is the problem it’s what we like to call the “seat”. Think of it this way. Say you have a jar and a lid. In order for there to be an air tight seal the lid (in this case the washer) needs to sit flush with the Jar (in plumbing terms the seat). If the jar has a chip there will be no air tight seal, it’s the same with the seat. So, in other words the seat is probably damaged and needs to be repaired.
Sometimes. Under your sink is what we call a “trap”. Its used as a water seal to trap the bad odour coming through the sewer lines, but good news is they can sometimes catch or “trap” items such as earrings.
The short answer to this in our opinion is NO! Baby wipes definitely not! They are not designed to break down in water. Flushable wipes are debateable, but our saying is if in doubt keep it out! The only paper we advise you to put in your toilet is toilet paper! Tissues are a no go too they are designed to hold moisture aka snot that comes from your nose, so they are designed not to breakdown when they get wet! Imagine if they did break down in your hands? yuck!!
Yes, but not likely. On the outside of your property there will be a grate normally located outside your kitchen or bathroom that is known as a gully. These need to be kept uncovered so if there is a potential blockage the sewer can escape outside through the gully and not in your home. In our years of experience we have only come across one scenario where someone had covered the gully with rocks and the sewer had backed up into the home throughout most of the house. This home was then declared toxic and the occupants had to vacate.
No there will need to be some considerations made. Like is it an S-Trap or a P-trap? Is the inlet for the water and the bottom or top of the suite? Will the drainage line up, can we off set it? Best to get some advice before purchasing your new throne.
