Hello everyone,
I am currently renovating our single-family house built in 1984. In particular, two bathrooms are to be completely renewed and the drinking water installation (formerly copper piping) is to be renewed up to the basement with composite plastic pipes. I would like to handle the planning and installation myself (Viega Raxofix press system etc. is available). The following things were/are important to me in the design:
1. Orientation to the state of the art in drinking water hygiene >> no dead legs and compliance with the 3-liter rule;
2. The installation should be feasible with minimal remodeling effort >> complete hot water circulation is therefore ruled out for me, so I am planning with floor circulation and series lines on the floor;
My current design is as follows:
--------------------------------------------------------------
Cold water pipe network
Design according to DIN806-3
Question 1: DIN specifies a maximum pipe length of 5 m for section 3 and 10. Are 5.9 m and 8 m still feasible?
Question 2: For section 8 (beginning of the riser), my calculation actually results in an inner diameter of 20 mm (26 x 3 mm), but I would like to use only two different pipe dimensions. Does this work with the 20 mm pipe at the beginning?
--------------------------------------------------------------
Hot water pipe network
Design according to DIN806-3 (despite circulation)
Question 1: DIN specifies an inner diameter of 14 mm (18 x 2 mm) for section 4. Does this also work here if you keep the 20 mm pipe up to the shower?
Question 2: DIN mentions DN10 circulation pipes. Prefer these or stay with 16x2?
Question 3: According to calculations, a 16x2 pipe is sufficient for the riser from the ground floor to the upper floor (section 2). Should the reduction take place in the ground floor or only in the upper floor (as shown in the illustrated pipe network)?
--------------------------------------------------------------
I would be interested in your general feedback on the design and the questions above.
Thank you!
