That's too much leakage for me to be happy with.  

I make them look nice by framing around the inside with 1x2, putting rigid foam insulation in and covering with bead board, caulk and paint and they look great and eliminate the air leakage from the cheap accordion fillers.      500 bucks and an hours work versus 6-8k. 

I didnt understand, why he wants to hide this leakage from demositurizer hose from insurance, when at first he said it happens sometimes.

More than four months rent were lost between missed rent payments and legal fees to evict the tenant.The next tenant was much better, but had frequent complaints regarding legitimate problems: -bathroom sink hot water knob that didn't work-rat urine smell coming from the vents-water leakage from the toilet(I understand that problems occur, particularly with properties of this age, but it was surprising/disappointing considering I paid Ohio Cashflow $64.9k for a property they bought for almost half the price, then, even after having done improvements, still required frequent repairs.)3.

Originally posted by @Account Closed:I would tell the tenant to go buy some Drano.Never Ever.Don't tell your tenant to put drano on there own, if they pour to much than your pipes will get A whole and make a huge leakage, you have to know how to use drano. 

Is there ANY sign of leakage anywhere near the pump?

The house just got foundation repaired, and obviously there’s a leakage at some point.

I had no way of knowing if the smell was from sewer gas or from the leakage, but one wasnt wet anymore so I assumed it was gas.

There's a lot of leakage in selling property thanks to the ridiculous fees.

You should have all your tenants sign some kind of forms saying if they don't report any  leakage tto you.
