Rodents in plumbing system - The only rodent which will invade a house through the plumbing system is going to be a rat. Norway rats are excellent swimmers and are proven to enter houses through drains and other plumbing (such as toilets!) . There's nothing worse than lifting your toilet lid to discover a live rat leaping from the bowl. Most rat problems of this sort can be avoided with the installation of grates on valves and drains in the pipes. If you're moving into an apartment building in town, be sure to ask your landlord if the pipes are rat-proof. Some older buildings don't have the latest and greatest when it comes to rat avoidance.
Norway rats, otherwise called sewer rats or brown rats, are famous for their ability to float into houses through pipes and drain outlets. Brown rats aren't the best climbers, but they can make it far enough in a construction to venture in through the roof. For those who have any sort of roof pipes, as many flats in towns do, you might need to be certain a grate was installed which will prevent rats from getting the pipes. The most common rat on a roof would be the Black Rat that has far better scaling abilities than the Norway Rat. Black Rats aren't known for their tendency to float through pipes. In the scheme of things, rats invading a house through plumbing on the roof are comparatively rare. A rat of any sort may enter a house in the roof, through a pipe or a port not shielded. Keeping your house guarded against this sort of intrusion is the secret. Make certain all openings have the right caps or grates. Any holes or damaged areas of the house have to be repaired. Failure to do these basic steps, particularly in urban settings, might result in a severe rodent matter.
Plumbing stack repair - Rats can get in the plumbing system by scaling down the pipes stacks on the roof. To fix a plumbing stack that's been damaged by a rat, then you should consider employing a professional plumber. There are special codes that will need to be adhered to, and improper installation may result in more issues later on. Some plumbing stacks run the whole height of a structure, through the outside wall. Damage on a stack of that caliber is going to be an extremely tough fix. The damaged area must be found and then access created so the remainder of the building doesn't have to be disturbed. If you are lucky, and seals are the only portion of the stack that have to be replaced, the cost of such a project shouldn't be too intimidating. Any time you need to open a wall, however, you'll be taking a look at significant repair invoices. All this could have been prevented with good exterior care of the construction.
Yes, rats can enter your home through the pipes pipes, and then up through your toilet bowl. It isn't common, but it does occur. Most commonly it is the Norway Rat, or Brown Rat, which favor underground urban places, sewers, and enter the plumbing system. These rats are amazing climbers and can hold their breath to make it through the de trap along with other neighboring areas. For those who have a grate or valve installed on your pipes outflow, you're not at risk.
You might think that you could flush out a rat down the toilet, but it would be more inclined to jump out before being flushed down. Once inside the home, you've got to trap the rat, or expect your pet will get it, since it won't return down the toilet water. If you see that your toilet paper being eaten at night, perhaps a rat is doing it, but it probably did not come up through the commode. Some folks believe you can stop a rat in this scenario with a bathroom guard. I have got to be honest though, rats in the bathroom are extremely rare.
Install vents in your plumbing stacks. Install a valve or display in your pipes outflow before it enters the sewer pipes. Keep the toilet seat and lid shut, and if you see one, slam it shut and call an expert!
