Installing a pump in hotpress for shower

caze

I live in a duplex unit above an appartment and i'm fed up with only a dribble of water out of my shower, poor water pressure.

I'm thinking of getting a pump installed in my hot press to feed the onsuite gravity feed shower and mixer tap shower in main bathroom.

Now I'm don't know if it's possible to isolate these 2, or would i have pumped water throughout the whole system?
I suppose if that was the case then I could turn off the pump unless someone was having a shower?

Anyone know roughly how much a decent pump would be? Or any tips on such a setup?

Thanks!

For the shower you will need a twin impeller. There is cheap ones in argos but i imagine if you go with a plumber supply and fit of a quality 1,5 bar will set you back no more than 400 euro.

replacing the shower with a pumped version may be a cheaper and better option, particularly due to noise issues with pump in hot press.

this solution wont be as good as a full blown 3 bar 18l/m job but you could have a issue with neighbours

You cannot use a 3 bar pump on a standard system it will empty your tank in know time. The simplest way to explain it is useing a petrol tank for a mini on a bus.... The bus will go but empty in no time.

A hotpress pump will be far quiter to the householder than a pumped t90 on a stud wall. Seriously....

I live in a duplex too. Friend of mine put a pump in my hotpress and it's brilliant. Great pressure etc.... Not really that noisey either. I would say a t90 would be louder;).

Defo! Op take this advise, the pump is a better option imo.
1.5 bar is also more than enough. If you have an attic, you can bring the new pipe run easy enough, and down the stud to the shower valve, sot he pump will only feed the shower.

haven't read through all the posts but personally I think you would be better with a whole house pump... why just boost the shower if everywhere is crap? would be just as easy to do just make sure its twin propeller so it feeds hot and cold and tell a plumber wholesaler what its to feed, shower, bath, basin, kitchen sink etc and they will tell u what pressure u need

Put a 1.5bar onto my en-suite gravity fed pump, should cost about €300 for a decent one. To pump bath aswell would probably involve pumping whole system which can be a pain (especially if someone uses toilet in middle of night and you have an old-style ballvalve in cistern!). However, if you can't get access to shower feed under floorboards and have to go 'up & over' you will probably need a negative head pump which will set u back nearer €900. GL.

Hi. Just wondering why do you need to put a pump in the hot press in the first place? Can you still use a power shower when you do this? Thanks

a pump will convert your normal thermostatic shower into a powershower. you cannot have a pump and use a shower with a built in pump as well e.g. an aquastream, mira excel etc.

Depends on quality of the pump ,some of them are over a grand.

I will need a pumpo to power 2 seperate showers - 1 in an ensuite and the 2nd one in the regular bathroom, they are both on the same floor as is the hot water cylinder, the cold water tank is in the attic on a raised platform.
I have been told that i need a 3 bar twin impeller brass pump with a positive head.

You will also need a bigger cylinder. Between the pump and the cylinder you wont see much change out of 2k.

I think its always handy to have a t90 or mira elite in a house ,even as a back up shower.
Unless their is solar panels in a house and even then ,it's still handy to have a back up shower:)

You will only need a 3 bar pump if you can expect that both showers will be running at the same time. Also that the pipes are sized correctly or some one will get a burnt bum:(
