A WASHINGTON INTENTION
sewer-Gas aud Dsck-aow Conquered.

sewcr-Gas and Back flow Conquered.
Dropping into the establishment of II. W.
Hamilton, corner Of Ninth and d streets, VIC
saw in practical operation one Of Downey's im.
proved sewer traps, and we want to rciterate
what We have stated in these columns efore,
that this invention Is one Of the most perfect
and most necdful that we have ever seen. 1t
is not necessary to dwell upon the evil effects
of back-ilow, or the more fatal scwc. gas. Ev-
cry one in this and other cities knows of his
own experience In greatcror less degree what
1t IL. 1t is only necessary to state that MIR.
Downey has succeeded absolutely in discover
ing remedy and preventative. He has re.
Gently added some new ideas, gained by exper.
icncc and experiments, and undoubtedly has
now got what he started out to get-a perfect
sewer trap.
During the foods Of the past two weeks the
trnps he has put in in various exposed portions
OF tho city were subjected to severe test, and
In no case did they fail to withstand ID, and as
a consequence premises which were always
flooded before on like occasions were left with.
out drop of back-fOw having entered. This
was only what any one examining the trap
would know would he the result Back flow
need have no terror to any one who has
DOWhcy S trap on his premises.
But that is not the only good quality Of the
trap. With 1t the entrance Of sewcr.gas Is i'm.
possible.
The trap not only makes perfect seal. but
1t furnishes ventilation to all the pipes on the
premises, and gives constant llow of air
throughout the full lcugth of pipe. and pre-
vents ANY siphcnagc taking place in the traps.
1t cuts oil all communication from the sewer
with the house, and yet allows water and waste
To irpglN iIUm tln hpUgN the
Ali the offensive odors that are generated In
the sOil-pipo within the house are also carried
and discharged above the roof, thus not only
preventing the entrance Of sewer.gas from
without the house, but also etfcctuilly dispOS-
ing of all the odors generated within. As a
health-preserying invention alone this trap
takes rank with the most useful of the age
and Mr.. Downey not only deserves the patron
age of all persons living in cities with saver
systems, but their thanks as well, for there is a
10 more insiiiOus or health. destroying foe
known than scwer-gas.
Mr. Downcy has gone further with his inven-
tion than hOusc.trAns II 10 has invented simple
attachment 'or re = Orncr traps, that without
a.Cent of cost the city authorities can elec.
tually prevent the llow Of lOul air and sewer
gas from them. 1t is only necessary to see n
strect-corncr trap cleaned once to appreciate
the amount of filth that is all the time lying
| in these traps, giving out their foul OdOrs and
/ hbSlbus gas 10 tue surrounding atmosphere.
| By Mr.. DOwncy's attachment all this filth is
| prevented, and the traps rendered at all time
| clean and free. The city authorities that,
after having this invcntiOn shown to them,
fail to have them put in ut every Street.cormer
suriacc-drainage trap, will he neglectiul of
| their duty and care for the health Of the
| city.
Mr. Downcy has spcn, all his time for sev.
| eral years and no limit Of money IN bringing
his trap to perfection, aud has steadily refused
all offers to introduce it elsewhere until he had
thoroughly established its perfect reliability at
| home. lie has now reached that point, having
the highest possible endorsements frOr. every
| person who has used it, lie has already made
arrangements with Mr.. Hamilton, one Of our
| most prominent plumbers, corner Of Ninth aujl
d streets, for supply ing the District. Mr..
| Hamilton has all the while had the most per.
| feet confidence in the success of the trap. but.
from the experience gained by the tests Of the
| late foods he is 50 assured that he guarantees
| to the fullest extent all til" traps he puts In
| Mr.. Hamilton has both STYLES Of tny traps ia
| practical operation, and will BE- at all times
| pleased to show them to the public and explain
| their workings, aud We advise all interested.
| and who IS not = to call and examine it,
| Mr.. DOwuey goes East this week, iu answer
TO several invitations from plumbers OF other
| cities, TO Introduce his trap. As Wa5llingtO
uiaus, proud Of his success at home, we wish
him that sucrcss abroad which the merits o
| his invention 80 fully deserve.
