Fitted this today, worked first time. Without your advice I could not have done it. Thank you for your help

[@MJTiffPlumbing]

No worries buddy 👍🏼👍🏼

[@jazzbansal8097]

Brilliantly explained .. my mate asked me how to fit one .. I sent this video .. this must be the best video on how to do the job step by step .. thank u mark

[@MJTiffPlumbing]

Thanks buddy 👍🏼👍🏼

[@Tomo-fo4bv]

Absolutely brilliant thank you. Great explanation and for a total "plumbing novice" like myself...just so easily followed.🤗

[@MJTiffPlumbing]

Thanks buddy

[@aidykeenan5824]

By far the best plumbing videos on KZbin 👍

Thanks Mark... glad you liked it. Plenty more to come buddy 👍🏼👍🏼

[@marksherrit5874]

Great video. Only difference I do is make up three pipework from the pump before I cut into the 22 pipes.

[@matthewstevenson8795]

Brilliant video. It makes such an improvement to hot water flow.

[@MJTiffPlumbing]

Thanks Matt, glad you enjoyed it.... Customer was very happy, now to get onto fitting the new bath and shower now the hotwater is usable.

[@markjhewlett]

Great Job Mark, just found your channel, really helps us guys training in the trade. Keep up the videos :-)

[@MJTiffPlumbing]

@@markjhewlett thanks buddy. Glad you liked it. Just seeing how I get on with it, plenty of people have said they are enjoying the videos so I will carry on. Hopefully people can get something from them.

[@DSS-Renzokuken]

This is what I need. My father in law set the pump up next to the shower and its so loud. I wanted the pump providing pressure to the whole house not just 1 shower. Will get a plumber to do this! Thanks great video

[@MJTiffPlumbing]

No problem buddy

[@b21playa]

Hi. Great video. My hot water outlet goes up, how could I plumb this in? Guessing my vent is further up

Thanks... gotta love a good bend

[@xclusive463]

So much easier very helpful

[@MJTiffPlumbing]

Glad it helped!

[@Runmachine49]

Will it give good pressure to shower head as well or is it better to have showet pump???

[@JayG2K]

Can this be fitted on a system boiler? we have a cylinder and CW tank in loft but no Feed and expansion tank.

[@Rewind787]

Would you recommend fitting a pump as opposed to fitting an electric shower? (Mira Airboost). I'm after a really good shower. (Conventional boiler with hot water tank in airing cupboard, water tanks in loft... (in other words not a combi boiler). Thanks.

[@johnaustin1825]

Hi Dean, May I ask the size/capacity of your cylinder please?

[@jazzbansal8097]

Hi Mark would the pump run the showers as well as the pressure in the hot water system

[@GRIFF22]

Great video, I'm about to put this job out. Approx what would the cost of this job be ?

[@davidkneale7455]

Any problem with reconnecting with a 15mm vent pipe? I don't know why itis 15mm!

[@Rayzorit]

Great video very well explained. Tell me is it possible to have the pump coming on automatically when the water is turned on?. Instead of having to switch it each time.

[@MJTiffPlumbing]

It does come on when it’s called for by the water demand👍🏼

[@johnaustin1825]

Great video. My plumber says a 3.0 bar could be too fierce and cause shaking of the pipes?

[@deanholloway7755]

I would rather know how long the hot water would last with that tank if you have a shower 🙂

[@yensabi]

Nice job Mark , I always use CT1 now instead of paste on my threaded water unions and never had a single drip it’s great stuff with dozens of other uses.. cheers mate and keep up the good work...👍

[@MJTiffPlumbing]

Never used CT1 on a thread before.... always just use ptfe and paste. Might give it a try on something

[@philippartridge9581]

Thread lock liquid from loctite

[@johnaustin1825]

Do I still need a separate shower pump?

[@jasonkiernan5749]

Great video. Fair play. We got a new tap in the kitchen and the hot water pressure is very low. If we installed that pump would it affect the triton pumped electric show we have in the house. Also what size ct force pump would we need. Thanks very much for your help. Subscribed there now too. Great stuff.

[@MJTiffPlumbing]

If your on a gravity fed system use the Salamder CT Force 30 and pump your whole hot water for the house as per this video mate👍🏼👍🏼

[@jasonkiernan5749]

@@MJTiffPlumbing that's great thanks

[@manjsingh6500]

Your inspiring

[@MJTiffPlumbing]

Wow... thanks man 👍🏼

[@hopdjandy]

When i fitted mine it was hot and cold tank fed to shower bare in mind if your cold is also tank fed get a pump which does both on cold outlet on tank in loft as the hot will over power the cold

[@MJTiffPlumbing]

👍🏼👍🏼

[@jonnysegway7866]

Was the cold also gravity fed? Did that need a separate pump? Given the choice is a combined pump better (hot and cold)?

[@MJTiffPlumbing]

This was just to boost the hot water as it was poor…. Cold was mains fed

[@richardheywood6392]

Would this pump work in my situation? My house has no gas or oil. My central heating is just all old storage heaters. I have a cold water storage tank sitting above a direct hot water cylinder with the immersion heater in this heating my hot water. I did have all my cold taps and toilet (exception being kitchen cold tap) fed by gravity coming straight off tank and all my hot water obviously gravity from the cylinder. A plumber has re plumbed my bathroom so that every cold outlet is now directly off the mains but obviously hot water still gravity. I want a mixer shower on the bath ran straight off a deck mixer thermostatic tap on the bath. I've been told these require equal hot and cold inlet pressures. Would the ct force pump be the answer to this situation?

[@MJTiffPlumbing]

You would be better off fitting equal PRV before the pump to keep it the same👍🏼

[@charliesinden8711]

Nice pipe bending 👍🏻

[@MJTiffPlumbing]

Thanks buddy

[@simonstones1918]

I need to do this with a combination tank Tiff. Will it drain the cold water tank too quickly? It’s a ground floor flat with NO water pressure….

[@MJTiffPlumbing]

All depends on the sizes and the flow rate of the pump

[@simonstones1918]

@@MJTiffPlumbing going to be a single impeller 2.0 bar a reckon….. how can I get the mains pressure when there’s only a kitchen monobloc tap accessible?

[@callumnoor8442]

I have an issue with low hot water pressure (gravity fed-cylinder same level as shower). Good cold water pressure. Is it best to do this or have an electric shower fitted? An electrician will be needed to wire in the pump surely?

[@MJTiffPlumbing]

I personally would go for an electric shower as you don’t have great head of water…..

[@williamedward2259]

Great videos, glad to see plumbing only videos for a change. Handy looking grips what make are those?

[@MJTiffPlumbing]

Thanks buddy..... just trying to capture what I do day in day out.. Grip wise I think they are Rotherberg but will check for you

[@Whisgers]

Bahco and magnusson usually have black and orange coloured moulding on their grips,knipex are another great brand

[@miransalih1079]

Good man, that's best work mate, all with one hand, wouldn't that be easier for you to get a forehead camera strap which sill make things easier! Thanks matey

[@MJTiffPlumbing]

Cheers 👍🏼👍🏼 Yer I’ve looked into one

[@happyslapper07]

Hi that salamander pump where did you plug that in does it come with a plug.

[@MJTiffPlumbing]

Hi.... it comes with a 3 pin plug, so just plug and play.

[@streetstreet6908]

I dont have copper boiler it's the new type gravity fed boiler sorry its copper covered in new instelation but it's split in to to 2 with cold water tank on top with plastic lid so there's no place to put the s flange so wear would it go thanks

[@adamwernik]

Hello Did you get answer to your question? Did you installed new pump to your system?.I got exactly same system as yours. Thanks

[@davehunter6920]

those big pump pliers look good ...what make please mate?

[@davidodactyl]

Not sure if they are Knipex, but look similar. Knipex is a bit expensiv but they are very reliable.

[@matthewharvey1474]

Can my existing shower pump be used to increase preston the hot water taps?

[@MJTiffPlumbing]

Not really buddy

[@olliemackie7964]

Cheers Mark - why is it important to have an S flange with the pump, you mentioned something about airation? Otherwise someone would just tee off the existing to the pump. May have read somewhere you risk making the pump scream ?? Cheers mate

[@MJTiffPlumbing]

Hey Ollie You need an S Flange so you don't drag air from the top of the cylinder into the pump as this will cause the pump to overheat and give up. A lot of people do tee straight off and this is the result, the noise of the pump burning out is the "Scream" that youve read about

[@olliemackie7964]

@@MJTiffPlumbing ahh, brilliant. Really helpful. Soo many videos or threads saying to add a pump to add better pressure ie to shower or around house...but lots of teeing off going on. I can see why as the scary bit is the flange on the cylinder so most avoid it! Nice one mate

[@MJTiffPlumbing]

@@olliemackie7964 Just make sure its done right mate......

[@davehunter6920]

hi MJ... were there no fibre washers on that flange?

[@MJTiffPlumbing]

Hey Mate........yep, Paste then washer then paste then tap then paste............ Been there to many times so its a belt and braces approch to fitting them as you dont want it to leak

[@johnwaby4321]

That's made the hot water pressure a lot better 👍👍👍👍 love the pipe spaghetti under the old bath 😂😂😂😂 The pipe thread paste you use is it The non setting type ??

[@MJTiffPlumbing]

Thanks mate, yer loads better. Salamander pumps are great for that I find. Yer the paste doesn’t go off as such... works well

[@johnwaby4321]

Hi what make of pipe paste do you use please

[@MJTiffPlumbing]

I will find out when I’m in the van next and let you know 👍🏼👍🏼

[@edthelasttribe9580]

Actually what it does it protects from cavitation, that needle on a S-Flange prevents any air going into pump , which could cause a air bubbles. Cavitation is the formation of bubbles or cavities in liquid, developed in areas of relatively low pressure around an impeller. The imploding or collapsing of these bubbles trigger intense shockwaves inside the pump, causing significant damage to the impeller and/or the pump housing, and hot water cylinders get damaged quicker because, oxygen it’s a destroyer of everything inside a plumbing, usually causes corrosion . I hope 🤞 that’s more clearer information.

[@MJTiffPlumbing]

Not sure anything needed clearing up to be honest….🤷🏼‍♂️….. but thanks for your insight into whatever it was you was giving us an insight into….🤨👍🏼👍🏼

[@AaronM4275]

Copy and paste Job 😂

[@edthelasttribe9580]

It’s on a pump manufacturing instructions, what goes on internet, all gets uploaded from manufacturers.

[@phillipbull3673]

I think he just explained it with more syllables lol

[@halhilou02]

I've been looking for this video for ages thanks a lot mate. So am I right in thinking that a hot water pump can only be fitted to vented cylinders because unvented ones are usually pressurised vessels?

[@MJTiffPlumbing]

Unvented cylinders are pressurised mate…. No need for a pump

[@halhilou02]

@MJTiffPlumbing Thanks for confirming this mate. 1 more question, can you fit a circulation pump on the draw off?

[@MJTiffPlumbing]

No need to with a pressurised system You can if a Secondary hot water pump if needed

[@LD-xi1be]

Does this boost hot water for the shower too as well as all the taps?

[@MJTiffPlumbing]

All outlets

[@manjsingh6500]

😊👍

[@2009bager]

Can I install without top vavle on cylinder?

[@MJTiffPlumbing]

Nope, pump will burn out

[@tedlahm5740]

Not enough pressure from the city water system?

[@MJTiffPlumbing]

Just wanted more pressure

[@tonyclark9851]

How old is that clynder looks like all the insulation has been stripped of

[@MJTiffPlumbing]

It had an old school red heater jacket wrapped around it, cylinders used to be supplied completely bare...

[@daveayerstdavies]

The Surrey flange? Does nobody call it that any more?

[@MJTiffPlumbing]

Now and again I do, it’s got so many names

[@nickcollins7568]

Great job. But now the hot side of the shower will be pumped but the cold feed to the shower won't

[@MJTiffPlumbing]

The cold pressure is the same is the pumped hot pressure 👍🏼👍🏼

[@streetstreet6908]

Also, on some boiler gravity fed boilers, you may have to fit the s Flange on the side as not all boilers are not the same 😅

[@6969allgood]

Bit rough should have clipped inlet and out let pipes to pump on side wall for a proper class job

[@MJTiffPlumbing]

Thanks for watching

[@kennethhogan9115]

Great job that pump takes a while to cut in doesn't it

[@MJTiffPlumbing]

Thanks mate..... it’s the way the water flow switch is designed by Salamader

[@paulsmith2931]

Some right dodgy Chinese crappy bathroom fittings about, had a shower tray a couple of weeks ago that was higher underneath on one side, took some levelling out, might be a good idea to remove the lever valve from the hot water vent, potential bomb there if some idiot turns the hot water off and heat the cyclinder up.

[@deanholloway7755]

How did they manage that with only ten valves 😂😂😂

[@MJTiffPlumbing]

🤣🤣🤣

[@johnbower]

Good job except for all that sealing crap applied to the threaded fitting into the top of the cylinder, no need for sealing crap if a bit of time is spent ensuring all seal faces are clean.

[@MJTiffPlumbing]

We all do stuff different….. and this hasn’t leaked so it’s a win as that’s what counts👍🏼👍🏼

[@olliegueret4348]

That's not a gate valve! It's a ball action lever valve.

the shower pump is the solution for those who has a low pressure on the hot water quality work

[@MJTiffPlumbing]

Thanks mate.... it works a treat

[@antoniogalluccio4213]

I would swap the cylinder for an unvented instead of spending money in electricity to repressurise water that was delivered to me by water thames already pressurised over 3 bar as they spend money to do that. This system doesn't exist in Europe, just UK.

[@MJTiffPlumbing]

You wouldn’t swap it if you couldn’t afford it buddy….. it’s all down to the customers costings, what they want and how they want it….

[@steveyboyXRP]

salamander worst pumps on the market give noting but bother , shitty wee float switches in them, stuart turner only ones i use

[@MJTiffPlumbing]

Not had any issues with them to be fair, and if I have the customer service is spot on….

[@steveyboyXRP]

@@MJTiffPlumbing yeah if ur willing to wait for float switches as you can only get them direct from salamander . Get what ya pay for I guess
