Gextlk.men:— You can stroiiply and unhesitatingly recommend tht 

 " Eclipse " piston type reducing valve to florists. We have two purchased 

 of you last year. We would not have them out for double their cost and 

 find them as sensitive as a watch. We will be in Chicago soon to take ui 

 the vacuum system with you Yours truly,

 on thirteen runs of 2 inch pipe or eight 

 runs of 4-inch. ]f it is to have maxi-

 arrange valves so as to permit of re-

 twelve runs of pipe in all for the house. 

 It' you inrange tiie boiler as sug- 

 gesteil, ST'C that it is jiruperly enclosed, 

 >^o as to cut olV connection with the 

 plant hotises. Such an arrangement is 

 seldom advisable, because of the danger 

 of gas from the boiler-room getting in

PIPING FOR STEAM. 



We have seven houses lSxl7.j to 

 20x17.'}, side by side. The one syitem 

 furnishes steam heat for the seven 

 houses, store and residence. The boilers 

 are ;it one corner of the block of houses. 



We figured on running the nuiin flow 

 overhead along the ends of the houses 

 and the main return below; the flows to 

 be overhead and returns under the 

 benches. Our flows and returns are all 

 2-ineli pipe. IFow many 2-inch returns 

 will a 2-inch flow carry.' Should check- 

 valves be put in all returns before they 

 enter the main return and should there 

 be one or two valves on these lines? We 

 thought of having the highest point of 

 the main flow at the fartln:>r end slant- 

 ing toward the boiler, witii the bleeder 

 at the end connecting witii the return. 

 What size should the main flow bt; on 

 leaving the boiler; also tiie return upon 

 entering the lioiler.' We have two forty- 

 two horse-|(ower tulnilar boilers set same 

 height. Is it better to work the boilers 

 together or sejiai'ately .' W. &, S. 



I'lacli of your houses shotdd 1k> |pri>- 

 vided with a ."l-iin-h riser ;ni<l, if 2 inch 

 pi|K» is used for icturns, at Ivast nine 

 should lie installed to insure (50 degrees 

 in e(dil weather. The yoke for the boil- 

 ers and the main llnw should Ix; (5 im-h 

 pipe, l-'.iicli lioiler should he tapped with 

 a l-iii<h oiitN't. The (iimli flow should 

 co\er the emls i>f the first four houses; 

 the reiiniining three r;in lie (-.•irried by ii 

 4-inch tliiw. The main return, if it has 

 !l good f;ill .•llld is well alm\e the water 

 line in the bnileis. nei-d lie nnly 2 ineh. 

 If it is lielow the uat<'r line of the 

 boilers and eai-h n't urn fnuu the houses 

 is sealed In it. it had better be 4 inch. 

 The highest |iiiint in the main tinw 

 siKMild lie inimecli.-itely o\er the boilers it 

 possiliii'. All water ot' condens.atiou 

 slioiild lie carried with the flow of tiie 

 steam instead of against it, as \\ould be 

 tli(! case with the main flow sloping 

 towards the boiler with tli(> high jioint 

 .•it the far end. Install flu; bleeder with 

 swing joints at the end of the riser and 

 the return, at which jioiiit these two 

 |ii|ies should be closvr together than at 

 any other point. Put swing check-valves 

 on the return of each house before it 

 enters the main return, and a globe valvt? 

 in addition. < 'hecks are not to be de- 

 jiended upon to hold steam; they usual l.\ 

 work well enough when there is water in 

 the returns, but globe or gale valves 

 should be installed in Iwtli flow and 

 return to eadi house to insure comiilete 

 control. L. C ( '.
