plumbing

interesting, in an odd sort of way. in fact hadn't considered the matter at all -- the matter of the upstairs bathroom leaking into the nearby room on the same floor.

landperson said that it was because there had been no grout used in the shower floor drain installation. okay, took him at his word, and waited the requisite day or so for the grout to dry up prior to use.

the day of testing dawned, and there was another puddle of water in the other room.

hmm.

okay, now this doesn't make any sense. the shower floor is about an inch or two lower than the rest of the bathroom floor -- which is level with the rest of the second floor. so how is drainwater going up so as to puddle on the other side of the wall?

so, experiment time.

took a bath, this time though, in the old tried-and-true 'tabo and bucket' fashion.

end result, no puddle -- so far. from the indications, then, is that it may not have been the floor drain non-grouting that was the culprit, it may be that the piping to the shower head is leaking under pressure from the pressurized water tank.

we'll just have to see later, when we get back from work.
