How to choose a toilet flush
In everyday talk “flush” often mixes three things: bowl geometry (rimless), cistern mechanism/plate and bidet hygiene function. This page separates them. Basics: WC guide. Rimless Without the classic rim channel — easier cleaning. Example: Jika Mila rimless. That is not automatically a “weaker flush”; read manufacturer data. Cistern plate and frame In a wall-hung system the plate is the user’s “button”. It must match the frame/cistern standard. Do not buy a plate “because it is pretty” if the frame is different. Bidet / shower-toilet A separate function with extra connections. Exam..

How to choose a toilet
A toilet is the last thing you want to “guess” from a pretty picture. The wrong mounting type means a new frame in the wall, a wrong outlet to the stack or a pan that does not fit the niche. This guide teaches how to choose a WC step by step — then look at concrete models in the inventars.lv range. Renovation basics: plumbing guide. Type comparison: wall-hung or floor. Flush/rimless: flush. Start with mounting, not design Wall-hung or floor-standing? Wall-hung needs an installation frame/cistern in the wall. Floor — often a faster swap in a typical renovation. Where does the drainage g..

How to choose a basin
The basin decides which mixer fits, which trap fits and whether the vanity “stresses”. If you start with the prettiest ceramic, you often end with wrong holes or too short a spout. This guide teaches choosing a basin in sequence. Related: mixer, over/under/inset, trap, plumbing map. Three measurements before the catalogue Width × depth — how much fits the furniture/niche. Mixer holes — 1 hole, 3 holes, no hole (wall mixer). Trap and feed space — under a vanity there is often a “squeeze”. Size examples in the range WidthWhen typicalExample ~400 mmGuest WC, narrow nicheJika Z..

How to fit a compression fitting
A compression fitting joins pipe without welding — if the type fits the system. Examples: Elysee 20×½″, 20×¾″ male, 20×¾″ female, 20×½″ female. Basics: pipes guide. When this method fits The manufacturer specifies compression for this material. You have the correct diameter and seal/ring. You are not hiding a “temporary” joint in a wall with no access (if the instructions forbid it). Sequence Cut the pipe square; deburr inside/outside. Fit the nut and ring/seal in the correct order per the diagram. Push the pipe to the stop — incomplete insertion = leak. Tighten with a spann..

What pipe diameter and pressure mean
Numbers on a pipe card are not decoration. They decide whether the line survives pressure and temperature. Basics: guide. How to read 20×2.8 PN20 Rozma 20×2.8 PN20: 20 — outer diameter mm; 2.8 — wall thickness mm; PN20 — pressure class. Larger diameters: 25×3.5, 32×4.4. Glass-fibre / reinforced example: PP-R glass fibre — see card. SDR and hot water SDR links wall thickness to diameter. Hot water often needs a thicker wall / another class than cold. Use the manufacturer table, not “forum PN”. Why you do not downsize “by eye” Smaller diameter = higher losses, noise, weaker flow for ..

How to choose pipes and fittings
Pipes without fittings are only half a project. PP-R welding, PEX with press, and compression PP need different tools and skills. If you mix systems “because the diameter looks similar”, you end with a leak. This guide teaches you to choose as a system. Basics: plumbing guide. Comparison: PEX, PP or copper. Parameters: diameter and pressure. How-to: compression fitting. Three decisions before the metre Material / system — PP-R, PEX, compression, threaded brass/iron.
