Gentlemen:— You can strongly and unhesitatlngrly recommend the 

 " 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 Chicasro soon to take ui 

 the vacuum system with you. Yours truly,

little more radiation than the twelve 

 runs of 4-inch, at about two-thirds of 

 the cost and be cheaper to install and 

 just as satisfactory if the expansion 

 tank is placed twelve to fifteen feet 

 above the boiler. The cooler house, if 

 to be piped as a cool house, can be run 

 on thirteen runs of 2-inch pipe or eight 

 runs of 4-inch. If it is to have maxi- 

 mum piping, same as the other, then 

 arrange valves so as to permit of re- 

 ducing the number of service pipes to 

 th« numbers specified. If 2-inch pipe is 

 used a 2-inch riser with three 2-inch 

 returns can be placed under each bench. 

 If 4-inch pipe is used it may be dis-

tributed as follows: A flow and two 

 returns under each outside bench and 

 a loop, i. e., a flow and return under 

 each of the other benches, making 

 twelve runs of pipe in all for the house. 

 If you arrange the boiler as sug- 

 gested, see that it is properly enclosed, 

 so as to cut off connection with the 

 plant houses. Such an arrangement is 

 seldom advisable, because of the danger 

 of gas from the boiler-room getting in 

 the houses. It is best to have the boiler- 

 room completely cut oflE from the houses.

PIPING FOR STEAM. 



We have seven houses 18x175 to 

 20x175, side by side. The one syetem 

 furnishes steam heat for the seven 

 houses, store and residence. The boilers 

 are at one corner of the block of houses. 



We figured on running the main 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-inch pipe. How 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 farther end slant- 

 ing toward the boiler, with the bleeder 

 at the end connecting with the return. 

 What size should the main flow be on 

 leaving the boiler; also the return upon 

 entering the boiler? We have two forty- 

 two horse-power tubular boilers set same 

 height. Is it better to work the boilers 

 together or separately? W. & S. 



Each of your houses should be pro- 

 vided with a 3-inch riser and, if 2-inch 

 pipe is used for returns, at least nine 

 should be installed to insure 60 degrees 

 in cold weather. The yoke for the boil- 

 ers and the main flow should be 6-inch 

 pipe. Each boiler should be tapped with 

 a 4-inc'h outlet. The 6-inch flow should 

 cover the ends of the first four houses; 

 the remaining three can be carried by a 

 4-inch flow. The main return, if it lias 

 a good fall and is well above the water 

 line in the boilers, need be only 2-inch. 

 If it is below the water line of the 

 boilers and each return from the houses 

 is sealed by it, it had better be 4-incli. 

 The highest point in the main flow 

 should be immediately over the Iwilers if 

 possible. All water of condensation 

 should be carried with the flow of tlie 

 steam instead of against it, as Avould be 

 the case with the main flow sloping 

 towards the boiler with the high point 

 at the far end. Install the bleeder with 

 swing joints at the end of the riser and 

 the return, at which point these two 

 pipes should be closer 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 valve 

 in addition. Checks are not to be de- 

 pended upon to hold steam; they usually 

 work well enough when there is water in 

 the returns, but globe or gate valves 

 should be installed in both flow and 

 return to each house to insure complete 

 control. L. C. C.
