Replacing t90si muck

    Hi guys,

    I live in a high lime area in co. kildare and as such it ruins everything that combines heat and water. In the ensuite theres a t90si but it always gets caked in lime, and in fairness tritons are muck anyway for water pressure...

    The hot press is in the room adjacent and the cold water tank is above in the attic. What i want to do is scrap the triton and put in a pump with a mixer shower. I have gas so when ive heating on ive hot water.

    I was planning on getting a cold feed to the pump from the attic tank. The hot feed i was going to take from the bath feed so the hot can be boosted to the bath aswel.

    Is there flaws in my idea? Im a spark not a plumber ha.

    Regards
    Joe

    Yeah there is flaws. The cold feed will be fine. However the hot feed....

    If someone uses a hot tap especially the bath tap it will drain water from your pump line. This will introduce air into the pump and the resulting air will cause water hammer as such which will shorten the life of your pump.

    Also you risk that when anyone turns on a hot tap the drop in pressure will cause the flow switch on the pump to kick in. Again shortening its life.

    Why cant you have a surrey/warrick flange fitted to the pump?


    Also dont rule out a t90. Sometimes it only involves cleaning the internal filter.

    Im blessed that the t90 has the old elements, the ones that u could take apart and clean, not the sealed type. So thats prolonging the life of the shower. Filters are clean... They are just not a high flow rate shower.

    About using the bath feed to get hot water. I meant i'd like to do it like this... Cylindar> pipe> pump> pipe> y joint> bath feed shower feed. That way we can use the pump for the shower and to fill the bath. Though not at the same time...

    Does that make sense?

    Thanks for your reply though.
