Said heads are desirably provided with recesses 6 and 7 to accommodate the extremities of a foraminated tubular member 9 and the ends 10 of a tubular water-straining liner 10 of felt or other suitable material.

The member 9 and liner 10 serve as a partition to dividethe casingto afford within 'such partition a chamber 11 and an annular chamber 12 between the partition and the casing wall 5.

The inner chamber 11 is connected with a service pipe 14 which also supplies water to a sink or basin faucet 15 so that the filter may be utilized independently of or simultaneously with the faucet.

More particularly, the pipe connections 16 between the service pipe 14 and the faucet 15 includes in its length a T-fitting 16 into the branch of which is screwed the threaded end of a. so-called street-ell 17 which, in turn, is connected by nipples 18 and a valve 19 with a second ell 20 screwed into a socket 21 provided in the casing head 7 By such connections, water may be delivered into the inner chamber of the filter and thence after passing through the straining liner 10 and ables filtered or unfiltered water to be selectively drawn.

What I claim is The combination with a water supply pipe, a faucet, horizontal pipe connections including a T-fitting between said supply pipe and said faucet, and a filter having a side outlet spout, of a sectional horizontal inlet pipe connection for said filter, connected with said T-fitting provided in the aforesaid pipe connections and to the filter by I elbows, and a valve interposed between sections of the horizontal portion of said inlet pipe connection.
