Did you know that many modern sinks do not have an overflow drain anymore? Industry standards have changed because the chance of them getting rusted out and leaking were higher than overflowing the sink. I ran into a couple on an ’82 manufactured home this afternoon. At this point there is not much to do but to replace the sink, have a qualified person do the work.
A crawlspace needs ventilation to remain dry, but the vents must be elevated to where it does not create an entry point for water. To lower the possibility of the vent leaking, the vent should be raised. It could possibly be removed, but ventilation under a home is just as important as keeping water out. The area around this slap could benefit in a drain to limit the chance of water running into this area.
Termites usually travel up the wall a few feet and don’t need to travel much higher. But there is nothing stopping them from continuing into you attic space. Especially an attic space with moisture issues. If the termites can get their water in the attic then they won’t need to ever come down.
I see many flexible drains installed that are not leaking and have been leak free for years. But the chances of something getting stuck in the trap and clogging, or the chance of the connection leaking is greater than with a solid pipe installed by a licensed plumber. The image above shows the decrease in diameter of the flexible pipe over the solid waste pipe.
Asbestos, a very resilient and durable material, was banned in the early 1980’s due to associated health risks in the removal process. The asbestos fibers, when frayed, can crumble and float in the air we breathe. When the pieces lodge in the lungs, they will not break down and can lead to long term illness.
It is important to know that the tiles will not become a health risk until they are removed or demolished. A professional asbestos abatement company should test and remove the asbestos from your home as needed.
The mortar used to seal the roofing joints will crack with any movement of the tiles. It is normal to have to replace these every few years. Water can leak through the cracks if large enough and create further damage to the roof if not repaired.
