Con­cealed Cis­terns: Instal­la­tion and Main­te­nance Guide for Trade

Con­cealed Cis­terns are one of the eas­i­est, effec­tive and most aes­thet­i­cal­ly pleas­ing choic­es a home­own­er can make when design­ing what they want in their bathroom.

In the last decade, Con­cealed Toi­let Cis­terns have explod­ed in pop­u­lar­i­ty with those in the trade get­ting asked to fit more and more of them to stay inline with con­tem­po­rary con­sumer demand.

In this arti­cle, we’ll arm you with every­thing you need to know in order to fit a Con­cealed Toi­let Cis­tern effec­tive­ly in any bath­room set up, as well as tips to pass on to your cus­tomers regard­ing main­te­nance, ulti­mate­ly avoid­ing any headaches for you down the line.

First­ly, what exact­ly is a Con­cealed Toi­let Cistern?

A con­cealed cis­tern is a toi­let cis­tern set up that is designed to hide behind a wall or with­in fit­ted fur­ni­ture, the only part of the sys­tem that remains vis­i­ble once installed is the flush but­ton. Thus, cre­at­ing an aes­thet­i­cal­ly pleas­ing and min­i­mal­ist, mod­ern toi­let set up.

Which Dual Flush Con­cealed Cis­tern should you pick depend­ing on if you’re work­ing on a Res­i­den­tial or Com­mer­cial project?

At Rop­er Rhodes, we offer a vari­ety of mod­ern cis­terns, giv­ing you the cov­er­age you need for any install. Always guar­an­tee­ing the per­fect flush.

For res­i­den­tial projects, we rec­om­mend choos­ing between our Tor­rent Bot­tom Inlet Cis­tern, Cas­cade Side Inlet Cis­tern or our Com­fort Height Cis­tern, depend­ing on the appli­ca­tion where the cis­tern needs to be installed.

These cis­terns are designed to be fit­ted inside fur­ni­ture, mean­ing they’re more aes­thet­i­cal­ly and prac­ti­cal­ly at home in hous­es or apart­ments as opposed to com­mer­cial spaces.

For com­mer­cial work how­ev­er, we rec­om­mend our In-Wall Con­cealed Cis­tern. Com­mer­cial prop­er­ties often favour walled in appli­ca­tions as opposed to bath­room fur­ni­ture, this cis­tern is the ide­al prod­uct to accom­mo­date these set ups.

It is worth not­ing that all of these dual flush cis­terns are designed to fit floor mount­ed pans as opposed to wall hung toi­let set ups. If you require a cis­tern for a wall hung toi­let, please browse our Wall Hung Frame range.

How do Wall Hung Toi­let Frame set-ups dif­fer from stan­dard Con­cealed Cis­tern installs?

Due to the heavy nature of a ceram­ic wall hung pan. Con­cealed Cis­terns for these need to be sup­port­ed through a Wall Hung frame set up. Requir­ing a frame to be secure­ly fash­ioned to a stur­dy wall, with the cis­tern with­in. As a stan­dard floor mount­ed pan elim­i­nates the weight strain issue, cis­terns for these do not need the same lev­el of strength and support.

How To Cor­rect­ly install a Con­cealed Toi­let Cis­tern into fit­ted fur­ni­ture. Step by step.

Step 1: Attach the bracket

Before you look to install, check that the wall fix­ings are suit­able for the sur­face the cis­tern is being fixed on to in the bath­room. Always check there are no con­cealed cables or exposed pipework where you’re look­ing to drill. Mark your fix­ing points, grab your drill, insert the wall fix­ings, then secure the brack­et in place. The fix­ing brack­et has two prongs, cut them both to fit the work­top in question.

Step 2: Mount the Cis­tern onto the wall bracket.

Remove your cis­tern cov­er and slide the cis­tern onto the brack­et, take care when doing so to ensure a qual­i­ty fit. Fin­ish by secur­ing with the screw pro­vid­ed with the Cistern.

Step 3: Cut the flush pipe to size and attach to the Con­cealed Cistern.

Cut the 50mm end of the flush pipe square­ly, to pro­vide the cor­rect height to suit the pan, always make sure the tapered wash­er leads direct­ly into the valve. Do not tight­en the bot­tom nut when attach­ing, this is fac­to­ry set. If water escape is expe­ri­enced, check the pipe is insert­ed and the tapered wash­er is ful­ly fit­ted. Also, be sure the flush bend is braced against the wall. This will ensure there’s no ten­sion on the con­nec­tions which could cause fit­tings to leak.

Step 4: Con­nect the water sup­ply to the Cistern.

Be sure to use an approved dou­ble check valve to flu­id cat­e­go­ry 3 in addi­tion to an acces­si­ble ser­vice valve. Also, be sure that the inlet valve is ful­ly tight­ened to the base of the tank.

Step 5: Install the push but­ton to the Cistern

Insert your tubes through the Cis­tern cov­er and reat­tach. Then use your drill to cre­ate a 63mm cir­cle open­ing in the front of your unit pan­el. Feed your but­ton through and attach to the tubes. At Rop­er Rhodes Trade Solu­tions, we have a large col­lec­tion of push but­tons vary­ing in style, size and fin­ish. Mean­ing you always have the prod­uct you need to com­plete any bath­room set up.

Step 6: Fix the toilet.

When com­plet­ing this step, sup­port the flush pipe when locat­ing the toi­let onto it so the flush con­nec­tion does­n’t break.

Step 7: Alter and check the flush volume.

The flush­ing vol­ume can be adjust­ed until you find your desired flush. The tank is fac­to­ry set to flush at 6 and 3 litres, but can be amend­ed. Allow­ing full flush flex­i­bil­i­ty and cre­at­ing a toi­let set up that the end user is hap­py with.

Step 8: Amend the water level.

Adjust the fill valve to increase / decrease the water lev­el, giv­ing you the free­dom to find the ide­al flush for the toi­let in question.

Step 9: Pro­ceed with any final checks and clean the area.

Ensure the cis­tern cov­er is cor­rect­ly clipped onto the tank, this will pre­vent any splash escap­ing. We also rec­om­mend you ensure that the con­nec­tions are water­tight before seal­ing into the furniture.

Step 10: Re-attach the front fur­ni­ture panel

Now sat­is­fied with the flush vol­ume and water lev­el, attach your front fur­ni­ture pan­el back onto the unit slow­ly, ensur­ing the unit has full strength and is in place secure­ly. This com­pletes the cis­tern installation.
