I have a marielle soap dispenser, but it does not pump soap.It is new I just use it for one month

It needs replaced. Get the parts and it will come with the instructions to get you back pumping soap.

It's a new faucet, call Price Pfister and make them overnight you a new one; they are really helpful.

mabe the straw it self is blocked , try to clean out the inside of the straw and the head part and let me know if that dosent help and ill brain storm some more

Make sure the clear tube is inserted into the pump head properly.Make sure the tube is not kinked. try filling the bottle full of water and try pumping the water out first. Sometimes the dispenser gets an air lock and takes a bit of continuous pumping to get it to work

Two things spell trouble for these poorly engineered units:water and thick soap...

Inside these pumps is a metal ball for
the check valve. any water in your soap
will corrode this ball, causing the pump
to lose it's prime...

Using soap thats too thick (like Dawn)
will cause the soap to harden around the moving parts and impede the pumping
action. Try a thinner soap, such as inexpensive pink hand soap.DO NOT
ADD WATER! (See above)

Hope this helps.

lift out pump and let soak in very hot water or run in dish washer pump probably clogged by hardened soap

Try pumping it and covering the hole with your finger until pressure builds. This usually works. Soap is heavier than water and it takes a little longer to move up.

if the balls fell out you need a new head,sorry.

Unfortunately it is a very common problem with soap dispensers. First before you replace the dispenser, dillute a small amount of water mix with the soap in the bottle of the dispenser to see in fact if the pump is deffective. It could simply be that the soap is too thick for the pump to work properly. As to replace it, call the manufacture of the faucet which I presume came with the dispenser and very often they will stand by their products and send you one free of charge.

Our brand new Avalon model had this problem. It sure appears to be a design defect or defective part. After contacting customer support, they sent a replacement pump (the internal part, not the whole unit).

After removing the unit from your sink, holding the top pull firmly with constant pressure on the pump assembly. It will pop off, but you have to pull pretty hard.

I suggest running water through the top of your unit before putting the new pump assembly on it. Ours had black 'junk' inside even though it was brand new. The new unit just slides on in the reverse process of removing the old one.
