Pittsburgh builders exchange

TO THE EDITORS OF THE AMERICAN ARCHITECT:-- Dear Sirs,--In a late issue of your journal an advocate of Trap-venting, says of ordinary S-traps "If drywall cost estimator the traps are filled even once in two months they will keep their seals intact." Most persons now pittsburgh builders exchange agree that S-traps which are back-vented in the ordinary manner require refilling by hand as often as once a fortnight. It is, therefore, clear that the system of back-venting pittsburgh builders exchange ceramic versus porcelain tile is a very dangerous one. It is now found (and strangely enough, even by its advocates) that it totally fails in this respect and that it requires an amount pittsburgh builders exchange of attention which experience and common-sense show us it will never receive. My experiments on the rate of seal-reduction through pittsburgh builders exchange evaporation produced by back-venting were made with the greatest care and show a more rapid loss than is generally supposed. If the reports of these experiments are studied, it will be seen that every precaution was taken to secure trustworthy results. Although my experiments on siphonage were made during the same year and on the same system of piping with those on evaporation, it will be seen by studying the drawings and text of the report that the former in no wise interfered with the latter. No experiments on siphonage were made while the water stood high in the traps during the tests for evaporation, and no disturbance of the water seals was made by this or any other cause during the evaporation tests. It would have been exceedingly careless and totally unnecessary to allow of any such disturbance. Moreover, most of the experiments on evaporation were made, as shown, on a stack so connected with the rest of the system of piping that such disturbance would have been impossible. Even had we not so carefully closed the inlet or house-side of the traps. I found that a warm flue caused the back-vent pipe to evaporate enough of the water from the seal of the trap to break it in less than a week, and I am confident that this often happens in practice. How short-sighted and foolish is it to endeavor to throw discredit on these experiments which were made with the greatest care and honesty and which were witnessed and subscribed to by impartial experts, and to argue that, because other experiments made under different conditions showed a somewhat slower rate of evaporation, therefore cases could never occur in which the more rapid rate might be encountered in practice.
